+about: Instructions and checklist for creating a release.

+labels: kind/release

+---
+
+# Open Match Release Process
+
+Follow these instructions to create an Open Match release. The output of the
+release process is new images and new configuration.
+
+## Getting setup
+
+**NOTE: The instructions below are NOT strictly copy-pastable and assume 0.5**
+**release. Please update the version number for your commands.**
+
+The Git flow for pushing a new release is similar to the development process
+but there are some small differences.
+
+### 1. Clone Repository
+
+```shell
+# Clone your fork of the Open Match repository.
+git clone git@github.com:afeddersen/open-match.git
+# Change directory to the git repository.
+cd open-match
+# Add a remote, you'll be pushing to this.
+git remote add upstream https://github.com/googleforgames/open-match.git
+```
+
+### 2. Release Branch
+
+If you're creating the first release of the version, that would be `0.5.0-rc.1`
+then you'll need to create the release branch.
+
+```shell
+# Create a local release branch.
+git checkout -b release-0.5 upstream/master
+# Push the branch upstream.
+git push upstream release-0.5
+```
+
+otherwise there should already be a `release-0.5` branch so run,
+
+```shell
+# Checkout the release branch.
+git checkout -b release-0.5 upstream/release-0.5
+```
+
+**NOTE: The branch name must be in the format, `release-X.Y` otherwise**
+**some artifacts will not be pushed.**
+
+## Releases & Versions
+
+Open Match uses Semantic Versioning 2.0.0. If you're not familiar please
+see the documentation - [https://semver.org/](https://semver.org/).
+
+Full Release / Stable Release:
+
+* The final software product. Stable, reliable, etc...
+* Example: 1.0.0, 1.1.0
+
+Release Candidate (RC):
+
+* A release candidate (RC) is a version with the potential to be the final
+  product but it hasn't validated by automated and/or manual tests.
+* Example: 1.0.0-rc.1
+
+Hot Fixes:
+
+* Code developed to correct a major software bug or fault
+  that's been discovered after the full release.
+* Example: 1.0.1
+
+Preview:
+
+* Rare, a one off release cut from the master branch to provide early access
+  to APIs or some other major change.
+* **NOTE: There's no branch for this release.** 
+* Example: 0.5-preview.1
+
+**NOTE: Semantic versioning is enforced by `go mod`. A non-compliant version**
+**tag will cause `go get` to break for users.**
+
+# Detailed Instructions
+
+## Find and replace
+
+Below this point you will see {version} used as a placeholder for future
+releases. Find {version} and replace with the current release (e.g. 0.5.0)
+
+## Create a release branch in the upstream repository
+
+**Note: This step is performed by the person who starts the release.  It is
+only required once.**
+
+- [ ] Create the branch in the **upstream** repository. It should be named
+  release-X.Y. Example: release-0.5. At this point there's effectively a code
+  freeze for this version and all work on master will be included in a future
+  version. If you're on the branch that you created in the *getting setup*
+  section above you should be able to push upstream.
+
+```shell
+git push origin release-0.5
+```
+
+- [ ] Announce a PR freeze on release-X.Y branch on [open-match-discuss@](mailing-list-post).
+- [ ] Open the [`Makefile`](makefile-version) and change BASE_VERSION entry.
+- [ ] Open the [`install/helm/open-match/Chart.yaml`](om-chart-yaml-version) and change the `appVersion` and `version` entries.
+- [ ] Open the [`install/helm/open-match/values.yaml`](om-values-yaml-version) and change the `tag` entries.
+- [ ] Open the [`cloudbuild.yaml`] and change the `_OM_VERSION` entry.
+- [ ] There might be additional references to the old version but be careful not to change it for places that have it for historical purposes.
+- [ ] Run `make release`
+- [ ] Create a PR with the changes and include the release candidate name.
+- [ ] Go to [open-match-build](https://pantheon.corp.google.com/cloud-build/triggers?project=open-match-build) and update all the triggers' `_GCB_LATEST_VERSION` value to the `X.Y` of the release. This value should only increase as it's used to determine the latest stable version.
+- [ ] Merge your changes once the PR is approved.
+
+## Complete Milestone
+
+**Note: This step is performed by the person who starts the release. It is
+only required once.**
+- [ ] Create the next [version milestone](https://github.com/googleforgames/open-match/milestones) and use [semantic versioning](https://semver.org/) when naming it to be consistent with the [Go community](https://blog.golang.org/versioning-proposal).
+- [ ] Create a *draft* [release](https://github.com/googleforgames/open-match/releases).
+- [ ] Use the [release template](https://github.com/googleforgames/open-match/blob/master/docs/governance/templates/release.md)
+  - [ ] `Tag` = v{version}. Example: v0.5.0. Append -rc.# for release candidates. Example: v0.5.0-rc.1.
+  - [ ] `Target` = release-X.Y. Example: release-0.5.
+  - [ ] `Release Title` = `Tag`
+  - [ ] `Write` section will contain the contents from the [release template](https://github.com/googleforgames/open-match/blob/master/docs/governance/templates/release.md).
+- [ ] Add the milestone to all PRs and issues that were merged since the last milestone. Look at the [releases page](https://github.com/googleforgames/open-match/releases) and look for the "X commits to master since this release" for the diff.
+- [ ] Review all [milestone-less closed issues](https://github.com/googleforgames/open-match/issues?q=is%3Aissue+is%3Aclosed+no%3Amilestone) and assign the appropriate milestone.
+- [ ] Review all [issues in milestone](https://github.com/googleforgames/open-match/milestones) for proper [labels](https://github.com/googleforgames/open-match/labels) (ex: area/build).
+- [ ] Review all [milestone-less closed PRs](https://github.com/googleforgames/open-match/pulls?q=is%3Apr+is%3Aclosed+no%3Amilestone) and assign the appropriate milestone.
+- [ ] Review all [PRs in milestone](https://github.com/googleforgames/open-match/milestones) for proper [labels](https://github.com/googleforgames/open-match/labels) (ex: area/build).
+- [ ] View all open entries in milestone and move them to a future milestone if they aren't getting closed in time. https://github.com/googleforgames/open-match/milestones/v{version}
+- [ ] Review all closed PRs against the milestone. Put the user visible changes into the release notes using the suggested format. https://github.com/googleforgames/open-match/pulls?utf8=%E2%9C%93&q=is%3Apr+is%3Aclosed+is%3Amerged+milestone%3Av{version}
+- [ ] Review all closed issues against the milestone. Put the user visible changes into the release notes using the suggested format. https://github.com/googleforgames/open-match/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aclosed+milestone%3Av{version}
+- [ ] Verify the [milestone](https://github.com/googleforgames/open-match/milestones) is effectively 100% at this point with the exception of the release issue itself.
+
+TODO: Add guidelines for labeling issues.
+
+## Build Artifacts
+
+- [ ] Go to [Cloud Build](https://pantheon.corp.google.com/cloud-build/triggers?project=open-match-build), under Post Submit click "Run Trigger".
+- [ ] Go to the History section and find the "Post Submit" build that's running. Wait for it to go Green. If it's red, fix error repeat this section. Take note of the docker image version tag for next step. Example: 0.5.0-a4706cb.
+- [ ] Run `./docs/governance/templates/release.sh {source version tag} {version}` to copy the images to open-match-public-images.
+- [ ] If this is a new minor version in the newest major version then run `./docs/governance/templates/release.sh {source version tag} latest`.
+- [ ] Copy the files from `build/release/` generated from `make release` to the release draft you created.  You can drag and drop the files using the Github UI.
+- [ ] Open the [`README.md`](readme-deploy) update the version references and submit. (Release candidates can ignore this step.)
+- [ ] Publish the [Release](om-release) in Github.
+
+## Announce
+
+- [ ] Send an email to the [mailing list](mailing-list-post) with the release details (copy-paste the release blog post)
+- [ ] Send a chat on the [Slack channel](om-slack). "Open Match {version} has been released! Check it out at {release url}."

+# Release history
+
+## v0.4.0 (alpha)
+
+### Release notes
+- Thanks to completion of Issues [#42](issues/42) and [#45](issues/45), there is no longer a need to use the `openmatch-base` image when building components of Open Match.  Each stand alone appliation now is self-contained in its `Dockerfile` and `cloudbuild.yaml` files, and builds have been substantially simplified.  **Note**: The default `Dockerfile` and `cloudbuild.yaml` now tag their images with the version number, not `dev`, and the YAML files in the `install` directory now reflect this.
+ - This paves the way for CI/CD in an upcoming version.  
+ - This paves the way for public images in an upcoming version!
+
+## v0.3.0 (alpha)
+  This update is focused on the Frontend API and Player Records, including more robust code for indexing, deindexing, reading, writing, and expiring player requests from Open Match state storage.  All Frontend API function argument have changed, although many only slightly. Please join the [Slack channel](https://open-match.slack.com/) if you need help ([Signup link](https://join.slack.com/t/open-match/shared_invite/enQtNDM1NjcxNTY4MTgzLWQzMzE1MGY5YmYyYWY3ZjE2MjNjZTdmYmQ1ZTQzMmNiNGViYmQyN2M4ZmVkMDY2YzZlOTUwMTYwMzI1Y2I2MjU))!
+
+### Release notes
+- The Frontend API calls have all be changed to reflect the fact that they operate on Players in state storage.  To queue a game client, 'CreatePlayer' in Open Match, to get updates 'GetUpdates', and to stop matching, 'DeletePlayer'. The calls are now much more obviously related to how Open Match sees players: they are database records that it creates on demand, updates using MMFs and the Backend API, and deletes when the player is no longer looking for a match.  
+- The Player record in state storage has changed to a more complete hash format, and it no longer makes sense to remove a player's assignment from the Frontend as a separate action to removing their record entirely.  `DeleteAssignment()` has therefore been removed.  Just use `DeletePlayer` instead; you'll always want the client to re-request matching with its latest attributes anyway.
+- There is now a module for [indexing and deindexing players in state storage](internal/statestorage/redis/playerindices/playerindices.go).  This is a *much* more efficient, as well as being cleaner and more maintainable than the previous implementation which was **hard-coded to index everything** you passed in to the Frontend API at a specific JSON object depth.
+    - This paves the way for dynamically choosing your indicies without restarting the matchmaker.  This will be implemented if there is demand.  Pull Requests are welcome!
+    - Two internal timestamp-based indices have replaced the previous `timestamp` index. `created` is used to calculate how long a player has been waiting for a match, `accessed` is used to determine when a player needs to be expired out of state storage.  Both are prefixed by the string `OM_METADATA` so it should be easy to spot them.
+- A call to the Frontend API `GetUpdates()` gRPC endpoint returns a stream of player messages. This is used to send updates to state storage for the `Assignment`, `Status`, and `Error` Player fields in near-realtime. **It is the responsibility of the game client to disconnect** from the stream when it has gotten the results it was waiting for!
+- Moved the rest of the gRPC messages into a shared [`messages.proto` file](api/protobuf-spec/messages.proto).
+- Added documentation to Frontend API gRPC calls to the [`frontend.proto` file](api/protobuf-spec/frontend.proto).
+- [Issue #41](https://github.com/googleforgames/open-match/issues/41)|[PR #48](https://github.com/googleforgames/open-match/pull/48) There is now a HA Redis install available in `install/yaml/01-redis-failover.yaml`.  This would be used as a drop-in replacement for a single-instance Redis configuration in `install/yaml/01-redis.yaml`.  The HA configuration requires that you install the [Redis Operator](https://github.com/spotahome/redis-operator) (note: **currently alpha**, use at your own risk) in your Kubernetes cluster.
+    - As part of this change, the kubernetes service name is now `redis` not `redis-sentinel` to denote that it is accessed using a standard Redis client.
+- Open Match uses a new feature of the go module [logrus](github.com/sirupsen/logrus) to include filenames and line numbers.  If you have an older version in your local build environment, you may need to delete the module and `go get github.com/sirupsen/logrus` again.  When building using the provided `cloudbuild.yaml` and `Dockerfile`s this is handled for you.
+- The program that was formerly in `examples/frontendclient` has been expanded and has been moved to the `test` directory under (`test/cmd/frontendclient/`)[test/cmd/frontendclient/].
+- The client load generator program has been moved from `test/cmd/client` to (`test/cmd/clientloadgen/`)[test/cmd/clientloadgen/] to better reflect what it does.
+- [Issue #45](https://github.com/googleforgames/open-match/issues/45) The process for moving the build files (`Dockerfile` and `cloudbuild.yaml`) for each component, example, and test program to their respective directories and out of the repository root has started but won't be completed until a future version.
+- Put some basic notes in the [production guide](docs/production.md)
+- Added a basic [roadmap](docs/roadmap.md)
+
+## v0.2.0 (alpha)
+  This is a pretty large update.  Custom MMFs or evaluators from 0.1.0 may need some tweaking to work with this version. Some Backend API function arguments have changed. Please join the [Slack channel](https://open-match.slack.com/) if you need help ([Signup link](https://join.slack.com/t/open-match/shared_invite/enQtNDM1NjcxNTY4MTgzLWQzMzE1MGY5YmYyYWY3ZjE2MjNjZTdmYmQ1ZTQzMmNiNGViYmQyN2M4ZmVkMDY2YzZlOTUwMTYwMzI1Y2I2MjU))!
+
+  v0.2.0 focused on adding additional functionality to Backend API calls and on **reducing the amount of boilerplate code required to make a custom Matchmaking Function**.  For this, a new internal API for use by MMFs called the [Matchmaking Logic API (MMLogic API)](README.md#matchmaking-logic-mmlogic-api) has been added.  Many of the core components and examples had to be updated to use the new Backend API arguments and the modules to support them, so we recommend you rebuild and redeploy all the components to use v0.2.0. 
+
+### Release notes
+- MMLogic API is now available.  Deploy it to kubernetes using the [appropriate json file]() and check out the [gRPC API specification](api/protobuf-spec/mmlogic.proto) to see how to use it.  To write a client against this API, you'll need to compile the protobuf files to your language of choice. There is an associated cloudbuild.yaml file and Dockerfile for it in the root directory.
+    - When using the MMLogic API to filter players into pools, it will attempt to report back the number of players that matched the filters and how long the filters took to query state storage.
+    - An [example MMF](examples/functions/python3/mmlogic-simple/harness.py) using it has been written in Python3. There is an associated cloudbuild.yaml file and Dockerfile for it in the root directory. By default the [example backend client](examples/backendclient/main.go) is now configured to use this MMF, so make sure you have it avaiable before you try to run the latest backend client.
+    - An [example MMF](examples/functions/php/mmlogic-simple/harness.py) using it has been contributed by Ilya Hrankouski in PHP (thanks!).   - The API specs have been split into separate files per API and the protobuf messages are in a separate file.  Things were renamed slightly as a result, and you will need to update your API clients. The Frontend API hasn't had it's messages moved to the shared messages file yet, but this will happen in an upcoming version.
+    - The [example golang MMF](examples/functions/golang/manual-simple/) has been updated to use the latest data schemas for MatchObjects, and renamed to `manual-simple` to denote that it is manually manipulating Redis, not using the MMLogic API.
+    - The API specs have been split into separate files per API and the protobuf messages are in a separate file.  Things were renamed slightly as a result, and you will need to update your API clients. The Frontend API hasn't had it's messages moved to the shared messages file yet, but this will happen in an upcoming version.
+- The message model for using the Backend API has changed slightly - for calls that make MatchObjects, the expectation is that you will provide a MatchObject with a few fields populated, and it will then be shuttled along through state storage to your MMF and back out again, with various processes 'filling in the blanks' of your MatchObject, which is then returned to your code calling the Backend API.  Read the[gRPC API specification](api/protobuf-spec/backend.proto) for more information.
+    - As part of this, compiled protobuf golang modules now live in the [`internal/pb`](internal/pb) directory.  There's a handy [bash script](api/protoc-go.sh) for compiling them from the `api/protobuf-spec` directory into this new `internal/pb` directory for development in your local golang environment if you need it.  
+    - As part of this Backend API message shift and the advent of the MMLogic API, 'player pools' and 'rosters' are now first-class data structures in MatchObjects for those who wish to use them. You can ignore them if you like, but if you want to use some of the MMLogic API calls to automate tasks for you - things like filtering a pool of players according attributes or adding all the players in your rosters to the ignorelist so other MMFs don't try to grab them - you'll need to put your data into the [protobuf messages](api/protobuf-spec/messages.proto) so Open Match knows how to read them.  The sample backend client [test profile JSON](examples/backendclient/profiles/testprofile.json)has been updated to use this format if you want to see an example.
+- Rosters were formerly space-delimited lists of player IDs.  They are now first-class repeated protobuf message fields in the [Roster message format](api/protobuf-spec/messages.proto). That means that in most languages, you can access the roster as a list of players using your native language data structures (more info can be found in the [guide for using protocol buffers in your langauge of choice](https://developers.google.com/protocol-buffers/docs/reference/overview)).  If you don't care about the new fields or the new functionality, you can just leave all the other fields but the player ID unset.
+ - Open Match is transitioning to using [protocol buffer messages](https://developers.google.com/protocol-buffers/) as its internal data format. There is now a Redis state storage [golang module](internal/statestorage/redis/redispb/) for marshaling and unmarshaling MatchObject messages to and from Redis. It isn't very clean code right now but will get worked on for the next couple releases.
+ - Ignorelists now exist, and have a Redis state storage [golang module](internal/statestorage/redis/ignorelist/) for CRUD access.  Currently three ignorelists are defined in the [config file](config/matchmaker_config.json) with their respective parameters. These are implemented as [Sorted Sets in Redis](https://redis.io/commands#sorted_set).
+ - For those who only want to stand up Open Match and aren't interested in individually tweaking the required kubernetes resources, there are now [three YAML files](install/yaml) that can be used to install Redis, install Open Match, and (optionally) install Prometheus. You'll still need the `sed` [instructions from the Developer Guide](docs/development.md#running-open-match-in-a-development-environment) to substitute in the name of your Docker container registry.
+ - A super-simple module has been created for doing instersections, unions, and differences of lists of player IDs.  It lives in `internal/set/set.go`.  
+
+
+### Roadmap 
+- It has become clear from talking to multiple users that the software they write to talk to the Backend API needs a name.  'Backend API Client' is technically correct, but given how many APIs are in Open Match and the overwhelming use of 'Client' to refer to a Game Client in the industry, we're currently calling this a 'Director', as its primary purpose is to 'direct' which profiles are sent to the backend, and 'direct' the resulting MatchObjects to game servers.  Further discussion / suggestions are welcome.
+- We'll be entering the design stage on longer-running MMFs before the end of the year. We'll get a proposal together and on the github repo as a request for comments, so please keep your eye out for that.
+- Match profiles providing multiple MMFs to run isn't planned anymore.  Just send multiple copies of the profile with different MMFs specified via the backendapi. 
+- Redis Sentinel will likely not be supported.  Instead, replicated instances and HAProxy may be the HA solution of choice. There's an [outstanding issue to investigate and implement](https://github.com/googleforgames/open-match/issues/41) if it fills our needs, feel free to contribute!

-Open Match is an open source game matchmaker designed to allow game creators to re-use a common matchmaker framework. It’s designed to be flexible (run it anywhere Kubernetes runs), extensible (match logic can be customized to work for any game), and scalable.
+[![GoDoc](https://godoc.org/open-match.dev/open-match?status.svg)](https://godoc.org/open-match.dev/open-match)

-Matchmaking is a complicated process, and when large player populations are involved, many popular matchmaking approaches touch on significant areas of computer science including graph theory and massively concurrent processing. Open Match is an effort to provide a foundation upon which these difficult problems can be addressed by the wider game development community. As Josh Menke — famous for working on matchmaking for many popular triple-A franchises — put it:
+Open Match is an open source game matchmaking framework that simplifies building
+a scalable and extensible Matchmaker. It is designed to give the game developer
+full control over how to make matches while removing the burden of dealing with
+the challenges of running a production service at scale.

-# Core Concepts
+## Support
 
-[Watch the introduction of Open Match at Unite Berlin 2018 on YouTube](https://youtu.be/qasAmy_ko2o)
-
-Open Match is designed to support massively concurrent matchmaking, and to be scalable to player populations of hundreds of millions or more. It attempts to apply stateless web tech microservices patterns to game matchmaking. If you're not sure what that means, that's okay — it is fully open source and designed to be customizable to fit into your online game architecture — so have a look a the code and modify it as you see fit.
-
-## Glossary
-
-* **MMF** — Matchmaking function. This is the customizable matchmaking logic.
-* **Component** — One of the discrete processes in an Open Match deployment. Open Match is composed of multiple scalable microservices called 'components'.
-* **Roster** — A list of all the players in a match.
-* **Profile** — The json blob containing all the parameters used to select which players go into a roster.
-* **Match Object** — A protobuffer message format that contains the Profile and the results of the matchmaking function. Sent to the backend API from your game backend with an empty roster  and then returned from your MMF with the matchmaking results filled in.
-* **MMFOrc** — Matchmaker function orchestrator. This Open Match core component is in charge of kicking off custom matchmaking functions (MMFs) and evaluator processes.
-* **State Storage** — The storage software used by Open Match to hold all the matchmaking state. Open Match ships with [Redis](https://redis.io/) as the default state storage.
-* **Assignment** — Refers to assigning a player or group of players to a dedicated game server instance. Open Match offers a path to send dedicated game server connection details from your backend to your game clients after a match has been made.
-
-## Requirements
-* [Kubernetes](https://kubernetes.io/) cluster — tested with version 1.9.
-* [Redis 4+](https://redis.io/) — tested with 4.0.11.
-* Open Match is compiled against the latest release of [Golang](https://golang.org/) — tested with 1.10.3.
-
-## Components
-
-Open Match is a set of processes designed to run on Kubernetes. It contains these **core** components:
-
-1. Frontend API
-1. Backend API
-1. Matchmaker Function Orchestrator (MMFOrc)
-1. Matchmaking Logic (MMLogic) API 
-
-It also explicitly depends on these two **customizable** components.
-
-1. Matchmaking "Function" (MMF)
-1. Evaluator (may be deprecated in future versions)
-
-While **core** components are fully open source and *can* be modified, they are designed to support the majority of matchmaking scenarios *without need to change the source code*. The Open Match repository ships with simple **customizable** example MMF and Evaluator processes, but it is expected that most users will want full control over the logic in these, so they have been designed to be as easy to modify or replace as possible.
-
-### Frontend API
-
-The Frontend API accepts the player data and puts it in state storage so your Matchmaking Function (MMF) can access it.
-
-The Frontend API is a server application that implements the [gRPC](https://grpc.io/) service defined in `api/protobuf-spec/frontend.proto`. At the most basic level, it expects clients to connect and send:
-* A **unique ID** for the group of players (the group can contain any number of players, including only one).
-* A **json blob** containing all player-related data you want to use in your matchmaking function.
-
-The client is expected to maintain a connection, waiting for an update from the API that contains the details required to connect to a dedicated game server instance (an 'assignment'). There are also basic functions for removing an ID from the matchmaking pool or an existing match.
-
-### Backend API
-
-The Backend API puts match profiles in state storage which the Matchmaking Function (MMF) can access and use to decide which players should be put into a match together, then return those matches to dedicated game server instances.
-
-The Backend API is a server application that implements the [gRPC](https://grpc.io/) service defined in `api/protobuf-spec/backend.proto`. At the most basic level, it expects to be connected to your online infrastructure (probably to your server scaling manager or scheduler, or even directly to a dedicated game server), and to receive:
-* A **unique ID** for a matchmaking profile.
-* A **json blob** containing all the match-related data you want to use in your matchmaking function, in an 'empty' match object.
-
-Your game backend is expected to maintain a connection, waiting for 'filled' match objects containing a roster of players. The Backend API also provides a return path for your game backend to return dedicated game server connection details (an 'assignment') to the game client, and to delete these 'assignments'.
-
-
-### Matchmaking Function Orchestrator (MMFOrc)
-
-The MMFOrc kicks off your custom matchmaking function (MMF) for every profile submitted to the Backend API. It also runs the Evaluator to resolve conflicts in case more than one of your profiles matched the same players.
-
-The MMFOrc exists to orchestrate/schedule your **custom components**, running them as often as required to meet the demands of your game. MMFOrc runs in an endless loop, submitting MMFs and Evaluator jobs to Kubernetes.
-
-### Matchmaking Logic (MMLogic) API
-
-The MMLogic API provides a series of gRPC functions that act as a Matchmaking Function SDK.  Much of the basic, boilerplate code for an MMF is the same regardless of what players you want to match together.  The MMLogic API offers a gRPC interface for many common MMF tasks, such as:
-
-1. Reading a profile from state storage.
-1. Running filters on players in state strorage.
-1. Removing chosen players from consideration by other MMFs (by adding them to an ignore list).
-1. Writing the matchmaking results to state storage.
-1. (Optional, NYI) Exporting MMF stats for metrics collection.
-
-More details about the available gRPC calls can be found in the [API Specification](api/protobuf-spec/messages.proto).
-
-**Note**: using the MMLogic API is **optional**.  It tries to simplify the development of MMFs, but if you want to take care of these tasks on your own, you can make few or no calls to the MMLogic API as long as your MMF still completes all the required tasks.  Read the [Matchmaking Functions section](#matchmaking-functions-mmfs) for more details of what work an MMF must do.
-
-### Evaluator
-
-The Evaluator resolves conflicts when multiple matches want to include the same player(s).
-
-The Evaluator is a component run by the Matchmaker Function Orchestrator (MMFOrc) after the matchmaker functions have been run, and some proposed results are available.  The Evaluator looks at all the proposed matches, and if multiple proposals contain the same player(s), it breaks the tie. In many simple matchmaking setups with only a few game modes and matchmaking functions that always look at different parts of the matchmaking pool, the Evaluator may functionally be a no-op or first-in-first-out algorithm. In complex matchmaking setups where, for example, a player can queue for multiple types of matches, the Evaluator provides the critical customizability to evaluate all available proposals and approve those that will passed to your game servers.
-
-Large-scale concurrent matchmaking functions is a complex topic, and users who wish to do this are encouraged to engage with the [Open Match community](https://github.com/GoogleCloudPlatform/open-match#get-involved) about patterns and best practices.
-
-### Matchmaking Functions (MMFs)
-
-Matchmaking Functions (MMFs) are run by the Matchmaker Function Orchestrator (MMFOrc) — once per profile it sees in state storage. The MMF is run as a Job in Kubernetes, and has full access to read and write from state storage. At a high level, the encouraged pattern is to write a MMF in whatever language you are comfortable in that can do the following things:
-
-[x] Be packaged in a (Linux) Docker container.
-[x] Read/write from the Open Match state storage — Open Match ships with Redis as the default state storage.
-[x] Read a profile you wrote to state storage using the Backend API.
-[x] Select from the player data you wrote to state storage using the Frontend API.
-[ ] Run your custom logic to try to find a match.
-[x] Write the match object it creates to state storage at a specified key.
-[x] Remove the players it selected from consideration by other MMFs.
-[x] Notify the MMFOrc of completion.
-[x] (Optional, but recommended) Export stats for metrics collection.
-
-** Open Match offers [matchmaking logic API](#matchmaking-logic-mmlogic-api) calls for handling the checked items, as long as you are willing to format your input and output in the data schema Open Match expects (defined in the [protobuf messages](api/protobuf-spec/messages.proto)). **  You can to do this work yourself if you don't want to or can't use the data schema Open Match is looking for.  However, the data formats expected by Open Match are pretty generalized and will work with most common matchmaking scenarios and game types.  If you have questions about how to fit your data into the formats specified, feel free to ask us in the Slack or mailing group.
-
-Example MMFs are provided in Golang and C#.
-
-## Open Source Software integrations
-
-### Structured logging
-
-Logging for Open Match uses the [Golang logrus module](https://github.com/sirupsen/logrus) to provide structured logs. Logs are output to `stdout` in each component, as expected by Docker and Kubernetes. If you have a specific log aggregator as your final destination, we recommend you have a look at the logrus documentation as there is probably a log formatter that plays nicely with your stack.
-
-### Instrumentation for metrics
-
-Open Match uses [OpenCensus](https://opencensus.io/) for metrics instrumentation. The [gRPC](https://grpc.io/) integrations are built-in, and Golang redigo module integrations are incoming, but [haven't been merged into the official repo](https://github.com/opencensus-integrations/redigo/pull/1). All of the core components expose HTTP `/metrics` endpoints on the port defined in `config/matchmaker_config.json` (default: 9555) for Prometheus to scrape. If you would like to export to a different metrics aggregation platform, we suggest you have a look at the OpenCensus documentation — there may be one written for you already, and switching to it may be as simple as changing a few lines of code.
-
-**Note:** A standard for instrumentation of MMFs is planned.
-
-### Redis setup
-
-By default, Open Match expects you to run Redis *somewhere*. Connection information can be put in the config file (`matchmaker_config.json`) for any Redis instance reachable from the [Kubernetes namespace](https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/). By default, Open Match sensibly runs in the Kubernetes `default` namespace. In most instances, we expect users will run a copy of Redis in a pod in Kubernetes, with a service pointing to it.
-
-* HA configurations for Redis aren't implemented by the provided Kubernetes resource definition files, but Open Match expects the Redis service to be named `redis-sentinel`, which provides an easier path to multi-instance deployments.
-
-## Additional examples
-
-**Note:** These examples will be expanded on in future releases.
-
-The following examples of how to call the APIs are provided in the repository. Both have a `Dockerfile` and `cloudbuild.yaml` files in their respective directories:
-
-* `examples/frontendclient/main.go` acts as a client to the the Frontend API, putting a player into the queue with simulated latencies from major metropolitan cities and a couple of other matchmaking attributes. It then waits for you to manually put a value in Redis to simulate a server connection string being written using the backend API 'CreateAssignments' call, and displays that value on stdout for you to verify.
-* `examples/backendclient/main.go` calls the Backend API and passes in the profile found in `backendstub/profiles/testprofile.json` to the `ListMatches` API endpoint, then continually prints the results until you exit, or there are insufficient players to make a match based on the profile..
-
-## Usage
-
-Documentation and usage guides on how to set up and customize Open Match.
-
-## Precompiled container images
-
-Once we reach a 1.0 release, we plan to produce publicly available (Linux) Docker container images of major releases in a public image registry. Until then, refer to the 'Compiling from source' section below.
-
-## Compiling from source
-
-All components of Open Match produce (Linux) Docker container images as artifacts, and there are included `Dockerfile`s for each. [Google Cloud Platform Cloud Build](https://cloud.google.com/cloud-build/docs/) users will also find `cloudbuild_COMPONENT.yaml` files for each component in the repository root.
-
-All the core components for Open Match are written in Golang and use the [Dockerfile multistage builder pattern](https://docs.docker.com/develop/develop-images/multistage-build/). This pattern uses intermediate Docker containers as a Golang build environment while producing lightweight, minimized container images as final build artifacts. When the project is ready for production, we will modify the `Dockerfile`s to uncomment the last build stage. Although this pattern is great for production container images, it removes most of the utilities required to troubleshoot issues during development.
-
-## Configuration
-
-Currently, each component reads a local config file `matchmaker_config.json`, and all components assume they have the same configuration. To this end, there is a single centralized config file located in the `<REPO_ROOT>/config/` which is symlinked to each component's subdirectory for convenience when building locally. When `docker build`ing the component container images, the Dockerfile copies the centralized config file into the component directory.
-
-We plan to replace this with a Kubernetes-managed config with dynamic reloading when development time allows. Pull requests are welcome!

-# Planned improvements
-
-## Documentation 
-- [ ] “Writing your first matchmaker” getting started guide will be included in an upcoming version.
-- [ ] Documentation for using the example customizable components and the `backendstub` and `frontendstub` applications to do an end-to-end (e2e) test will be written. This all works now, but needs to be written up.
-- [ ] Documentation on release process and release calendar.
-
-## State storage
-- [ ] All state storage operations should be isolated from core components into the `statestorage/` modules.  This is necessary precursor work to enabling Open Match state storage to use software other than Redis.
-- [ ] The Redis deployment should have an example HA configuration using HAProxy 
-- [ ] Redis watch should be unified to watch a hash and stream updates.  The code for this is written and validated but not committed yet. We don't want to support two redis watcher code paths, so the backend watch of the match object should be switched to unify the way the frontend and backend watch keys.  The backend part of this is in but the frontend part is in another branch and will be committed later. 
-
-## Instrumentation / Metrics / Analytics
-- [ ] Instrumentation of MMFs is in the planning stages.  Since MMFs are by design meant to be completely customizable (to the point of allowing any process that can be packaged in a Docker container), metrics/stats will need to have an expected format and formalized outgoing pathway.  Currently the thought is that it might be that the metrics should be written to a particular key in statestorage in a format compatible with opencensus, and will be collected, aggreggated, and exported to Prometheus using another process.
-- [ ] [OpenCensus tracing](https://opencensus.io/core-concepts/tracing/) will be implemented in an upcoming version.
-- [ ] Read logrus logging configuration from matchmaker_config.json.
-
-## Security
-- [ ] The Kubernetes service account used by the MMFOrc should be updated to have min required permissions.
-
-## Kubernetes
-- [ ] Autoscaling isn't turned on for the Frontend or Backend API Kubernetes deployments by default.
-- [ ] A [Helm](https://helm.sh/) chart to stand up Open Match will be provided in an upcoming version. For now just use the [installation YAMLs](./install/yaml).
-
-- [ ] Player/Group records generated when a client enters the matchmaking pool need to be removed after a certain amount of time with no activity. When using Redis, this will be implemented as a expiration on the player record.
-## CI / CD / Build
-- [ ] We plan to host 'official' docker images for all release versions of the core components in publicly available docker registries soon.
-- [ ] CI/CD for this repo and the associated status tags are planned.
-- [ ] Golang unit tests will be shipped in an upcoming version.
-- [ ] A full load-testing and e2e testing suite will be included in an upcoming version.
-
-## Will not Implement 
-- [X] Defining multiple images inside a profile for the purposes of experimentation adds another layer of complexity into profiles that can instead be handled outside of open match with custom match functions in collaboration with a director (thing that calls backend to schedule matchmaking)

-##v0.2.0 RC2 (alpha)
-  This is a pretty large update.  Custom MMFs or evaluators from 0.1.0 may need some tweaking to work with this version. Some Backend API function arguments have changed. Please join the [Slack channel](https://open-match.slack.com/) if you need help ([Signup link](https://join.slack.com/t/open-match/shared_invite/enQtNDM1NjcxNTY4MTgzLWQzMzE1MGY5YmYyYWY3ZjE2MjNjZTdmYmQ1ZTQzMmNiNGViYmQyN2M4ZmVkMDY2YzZlOTUwMTYwMzI1Y2I2MjU))!
-
-  v0.2.0 focused on adding additional functionality to Backend API calls and on **reducing the amount of boilerplate code required to make a custom Matchmaking Function**.  For this, a new internal API for use by MMFs called the [Matchmaking Logic API (MMLogic API)](README.md#matchmaking-logic-mmlogic-api) has been added.  Many of the core components and examples had to be updated to use the new Backend API arguments and the modules to support them, so we recommend you rebuild and redeploy all the components to use v0.2.0. 
-
-### Release notes
- - MMLogic API is now available.  Deploy it to kubernetes using the [appropriate json file]() and check out the [gRPC API specification](api/protobuf-spec/mmlogic.proto) to see how to use it.  To write a client against this API, you'll need to compile the protobuf files to your language of choice. There is an associated cloudbuild.yaml file and Dockerfile for it in the root directory.
-  - When using the MMLogic API to filter players into pools, it will attempt to report back the number of players that matched the filters and how long the filters took to query state storage.
-  - An [example MMF](examples/functions/python3/mmlogic-simple/harness.py) using it has been written in Python3. There is an associated cloudbuild.yaml file and Dockerfile for it in the root directory. By default the [example backend client](examples/backendclient/main.go) is now configured to use this MMF, so make sure you have it avaiable before you try to run the latest backend client.
-  - An [example MMF](examples/functions/php/mmlogic-simple/harness.py) using it has been contributed by Ilya Hrankouski in PHP (thanks!).   - The API specs have been split into separate files per API and the protobuf messages are in a separate file.  Things were renamed slightly as a result, and you will need to update your API clients. The Frontend API hasn't had it's messages moved to the shared messages file yet, but this will happen in an upcoming version.
-  - The [example golang MMF](examples/functions/golang/manual-simple/) has been updated to use the latest data schemas for MatchObjects, and renamed to `manual-simple` to denote that it is manually manipulating Redis, not using the MMLogic API.
-  - The API specs have been split into separate files per API and the protobuf messages are in a separate file.  Things were renamed slightly as a result, and you will need to update your API clients. The Frontend API hasn't had it's messages moved to the shared messages file yet, but this will happen in an upcoming version.
- - The message model for using the Backend API has changed slightly - for calls that make MatchObjects, the expectation is that you will provide a MatchObject with a few fields populated, and it will then be shuttled along through state storage to your MMF and back out again, with various processes 'filling in the blanks' of your MatchObject, which is then returned to your code calling the Backend API.  Read the[gRPC API specification](api/protobuf-spec/backend.proto) for more information.
-  - As part of this, compiled protobuf golang modules now live in the [`internal/pb`](internal/pb) directory.  There's a handy [bash script](api/protoc-go.sh) for compiling them from the `api/protobuf-spec` directory into this new `internal/pb` directory for development in your local golang environment if you need it.  
-  - As part of this Backend API message shift and the advent of the MMLogic API, 'player pools' and 'rosters' are now first-class data structures in MatchObjects for those who wish to use them. You can ignore them if you like, but if you want to use some of the MMLogic API calls to automate tasks for you - things like filtering a pool of players according attributes or adding all the players in your rosters to the ignorelist so other MMFs don't try to grab them - you'll need to put your data into the [protobuf messages](api/protobuf-spec/messages.proto) so Open Match knows how to read them.  The sample backend client [test profile JSON](examples/backendclient/profiles/testprofile.json)has been updated to use this format if you want to see an example.
-- Rosters were formerly space-delimited lists of player IDs.  They are now first-class repeated protobuf message fields in the [Roster message format](api/protobuf-spec/messages.proto). That means that in most languages, you can access the roster as a list of players using your native language data structures (more info can be found in the [guide for using protocol buffers in your langauge of choice](https://developers.google.com/protocol-buffers/docs/reference/overview)).  If you don't care about the new fields or the new functionality, you can just leave all the other fields but the player ID unset.
- - Open Match is transitioning to using [protocol buffer messages](https://developers.google.com/protocol-buffers/) as its internal data format. There is now a Redis state storage [golang module](internal/statestorage/redis/redispb/) for marshaling and unmarshaling MatchObject messages to and from Redis. It isn't very clean code right now but will get worked on for the next couple releases.
- - Ignorelists now exist, and have a Redis state storage [golang module](internal/statestorage/redis/ignorelist/) for CRUD access.  Currently three ignorelists are defined in the [config file](config/matchmaker_config.json) with their respective parameters. These are implemented as [Sorted Sets in Redis](https://redis.io/commands#sorted_set).
- - For those who only want to stand up Open Match and aren't interested in individually tweaking the required kubernetes resources, there are now [three YAML files](install/yaml) that can be used to install Redis, install Open Match, and (optionally) install Prometheus. You'll still need the `sed` [instructions from the Developer Guide](docs/development.md#running-open-match-in-a-development-environment) to substitute in the name of your Docker container registry.
- - A super-simple module has been created for doing instersections, unions, and differences of lists of player IDs.  It lives in `internal/set/set.go`.  
-
-
-### Roadmap 
- - It has become clear from talking to multiple users that the software they write to talk to the Backend API needs a name.  'Backend API Client' is technically correct, but given how many APIs are in Open Match and the overwhelming use of 'Client' to refer to a Game Client in the industry, we're currently calling this a 'Director', as its primary purpose is to 'direct' which profiles are sent to the backend, and 'direct' the resulting MatchObjects to game servers.  Further discussion / suggestions are welcome.
- - We'll be entering the design stage on longer-running MMFs before the end of the year. We'll get a proposal together and on the github repo as a request for comments, so please keep your eye out for that.
- - Match profiles providing multiple MMFs to run isn't planned anymore.  Just send multiple copies of the profile with different MMFs specified via the backendapi. 
- - Redis Sentinel will likely not be supported.  Instead, replicated instances and HAProxy may be the HA solution of choice. There's an [outstanding issue to investigate and implement](https://github.com/GoogleCloudPlatform/open-match/issues/41) if it fills our needs, feel free to contribute!

-# Open Match APIs
+# Open Match API
 
-This directory contains the API specification files for Open Match. API documenation will be produced in a future version, although the protobuf files offer a concise description of the API calls available, along with arguments and return messages.
+Open Match API is exposed via [gRPC](https://grpc.io/) and HTTP REST with [Swagger](https://swagger.io/tools/swagger-codegen/).
 
-* [Protobuf .proto files for all APIs](./protobuf-spec/)
+gRPC has first-class support for [many languages](https://grpc.io/docs/) and provides the most performance. It is a RPC protocol built on top of HTTP/2 and provides TLS for secure transport.
 
-These proto files are copied to the container image during `docker build` for the Open Match core components.  The `Dockerfiles` handle the compilation for you transparently, and copy the resulting `SPEC.pb.go` files to the appropriate place in your final container image.
+For HTTP/HTTPS Open Match uses a gRPC proxy to serve the API. Since HTTP does not provide a structure for request/responses we use Swagger to provide a schema. You can view the Swagger docs for each service in this directory's `*.swagger.json` files. In addition each server will host it's swagger doc via `GET /swagger.json` if you want to dynamically load them at runtime.
 
-References:

-Manual gRPC compilation commmand, from the directory containing the proto:
-```protoc -I . ./<filename>.proto --go_out=plugins=grpc:.```
+Lastly, Open Match supports insecure and TLS mode for serving the API. It's strongly preferred to use TLS mode in production but insecure mode can be used for test and local development. To help with certificates management see `tools/certgen` to create self-signed certificates.

Therefore, binary compatibility needs to be preserved\n  on changes to types.

The error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

+      "description": "- Simple to use and understand for most users\n- Flexible enough to meet unexpected needs\n\n# Overview\n\nThe `Status` message contains three pieces of data: error code, error\nmessage, and error details. The error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

Example (for message [google.protobuf.Duration][]):\n\n    {\n      \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n      \"value\": \"1.212s\"\n    }"

+      "description": "- Simple to use and understand for most users\n- Flexible enough to meet unexpected needs\n\n# Overview\n\nThe `Status` message contains three pieces of data: error code, error\nmessage, and error details. The error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

Therefore, binary compatibility needs to be preserved\n  on changes to types. (Use versioned type names to manage\n  breaking changes.)\n\nNote: this functionality is not currently available in the official\nprotobuf release, and it is not used for type URLs beginning with\ntype.googleapis.com.\n\nSchemes other than `http`, `https` (or the empty scheme) might be\nused with implementation specific semantics."

The error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

The error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

-** REST compatibility 
-Follow the guidelines at https://cloud.google.com/endpoints/docs/grpc/transcoding
-to keep the gRPC service definitions friendly to REST transcoding. An excerpt:
-
-"Transcoding involves mapping HTTP/JSON requests and their parameters to gRPC
-methods and their parameters and return types (we'll look at exactly how you
-do this in the following sections). Because of this, while it's possible to
-map an HTTP/JSON request to any arbitrary API method, it's simplest and most
-intuitive to do so if the gRPC API itself is structured in a
-resource-oriented way, just like a traditional HTTP REST API. In other
-words, the API service should be designed so that it uses a small number of
-standard methods (corresponding to HTTP verbs like GET, PUT, and so on) that
-operate on the service's resources (and collections of resources, which are
-themselves a type of resource). 
-These standard methods are List, Get, Create, Update, and Delete."
-
-It is for these reasons we don't have gRPC calls that support bi-directional streaming in Open Match.

+
+# This YAML contains all the build steps for building Open Match.
+# All PRs are verified against this script to prevent build breakages and regressions.
+
+# Conventions
+# Each build step is ID'ed with "Prefix: Description".
+#   The prefix portion determines what kind of step it is and it's impact.
+#   Docker Image: Read-Only, outputs a docker image.
+#   Lint: Read-Only, verifies correctness and formatting of a file.
+#   Build: Read-Write, outputs a build artifact. Ok to run in parallel if the artifact will not collide with another one.
+#   Generate: Read-Write, outputs files within /workspace that are used in other build step. Do not run these in parallel.
+#   Setup: Read-Write, similar to generate but steps that run before any other step.
+
+# Some useful things to know about Cloud Build.
+# The root of this repository is always stored in /workspace.
+#    Any modifications that occur within /workspace are persisted between builds anything else is forgotten.
+# If a build step has intermediate files that need to be persisted for a future step then use volumes.
+#    An example of this is the go-vol which is where the pkg/ data for go mod is stored.
+#    More information here: https://cloud.google.com/cloud-build/docs/build-config#build_steps
+# A build step is basically a docker image that is tuned for Cloud Build,
+#    https://github.com/GoogleCloudPlatform/cloud-builders/tree/master/go

-// OpenCensus Measures. These are exported as metrics to your monitoring system
-// https://godoc.org/go.opencensus.io/stats
-//
-// When making opencensus stats, the 'name' param, with forward slashes changed
-// to underscores, is appended to the 'namespace' value passed to the
-// prometheus exporter to become the Prometheus metric name. You can also look
-// into having Prometheus rewrite your metric names on scrape.
-//
-//  For example:
-//   - defining the promethus export namespace "open_match" when instanciating the exporter:
-//			pe, err := promethus.NewExporter(promethus.Options{Namespace: "open_match"})
-//   - and naming the request counter "backend/requests_total":
-//			MGrpcRequests := stats.Int64("backendapi/requests_total", ...
-//   - results in the prometheus metric name:
-//			open_match_backendapi_requests_total
-//   - [note] when using opencensus views to aggregate the metrics into
-//     distribution buckets and such, multiple metrics
-//     will be generated with appended types ("<metric>_bucket",
-//     "<metric>_count", "<metric>_sum", for example)
-//
-// In addition, OpenCensus stats propogated to Prometheus have the following
-// auto-populated labels pulled from kubernetes, which we should avoid to
-// prevent overloading and having to use the HonorLabels param in Prometheus.
-//
-// - Information about the k8s pod being monitored:
-//		"pod" (name of the monitored k8s pod)
-//		"namespace" (k8s namespace of the monitored pod)
-// - Information about how promethus is gathering the metrics:
-//		"instance" (IP and port number being scraped by prometheus)
-//		"job" (name of the k8s service being scraped by prometheus)
-//		"endpoint" (name of the k8s port in the k8s service being scraped by prometheus)

-// OpenCensus Measures. These are exported as metrics to your monitoring system
-// https://godoc.org/go.opencensus.io/stats
-//
-// When making opencensus stats, the 'name' param, with forward slashes changed
-// to underscores, is appended to the 'namespace' value passed to the
-// prometheus exporter to become the Prometheus metric name. You can also look
-// into having Prometheus rewrite your metric names on scrape.
-//
-//  For example:
-//   - defining the promethus export namespace "open_match" when instanciating the exporter:
-//			pe, err := promethus.NewExporter(promethus.Options{Namespace: "open_match"})
-//   - and naming the request counter "frontend/requests_total":
-//			MGrpcRequests := stats.Int64("frontendapi/requests_total", ...
-//   - results in the prometheus metric name:
-//			open_match_frontendapi_requests_total
-//   - [note] when using opencensus views to aggregate the metrics into
-//     distribution buckets and such, multiple metrics
-//     will be generated with appended types ("<metric>_bucket",
-//     "<metric>_count", "<metric>_sum", for example)
-//
-// In addition, OpenCensus stats propogated to Prometheus have the following
-// auto-populated labels pulled from kubernetes, which we should avoid to
-// prevent overloading and having to use the HonorLabels param in Prometheus.
-//
-// - Information about the k8s pod being monitored:
-//		"pod" (name of the monitored k8s pod)
-//		"namespace" (k8s namespace of the monitored pod)
-// - Information about how promethus is gathering the metrics:
-//		"instance" (IP and port number being scraped by prometheus)

-// When making opencensus stats, the 'name' param, with forward slashes changed

-// prometheus exporter to become the Prometheus metric name. You can also look
-// into having Prometheus rewrite your metric names on scrape.
-//
-//  For example:
-//   - defining the promethus export namespace "open_match" when instanciating the exporter:
-//			pe, err := promethus.NewExporter(promethus.Options{Namespace: "open_match"})
-//   - and naming the request counter "backend/requests_total":

-//   - results in the prometheus metric name:
-//			open_match_backendapi_requests_total
-//   - [note] when using opencensus views to aggregate the metrics into
-//     distribution buckets and such, multiple metrics
-//     will be generated with appended types ("<metric>_bucket",
-//     "<metric>_count", "<metric>_sum", for example)

-// OpenCensus Measures. These are exported as metrics to your monitoring system
-// https://godoc.org/go.opencensus.io/stats
-//
-// When making opencensus stats, the 'name' param, with forward slashes changed
-// to underscores, is appended to the 'namespace' value passed to the
-// prometheus exporter to become the Prometheus metric name. You can also look
-// into having Prometheus rewrite your metric names on scrape.
-//
-//  For example:
-//   - defining the promethus export namespace "open_match" when instanciating the exporter:
-//			pe, err := promethus.NewExporter(promethus.Options{Namespace: "open_match"})
-//   - and naming the request counter "mmlogic/requests_total":
-//			MGrpcRequests := stats.Int64("mmlogicapi/requests_total", ...
-//   - results in the prometheus metric name:
-//			open_match_mmlogicapi_requests_total
-//   - [note] when using opencensus views to aggregate the metrics into
-//     distribution buckets and such, multiple metrics
-//     will be generated with appended types ("<metric>_bucket",
-//     "<metric>_count", "<metric>_sum", for example)
-//
-// In addition, OpenCensus stats propogated to Prometheus have the following
-// auto-populated labels pulled from kubernetes, which we should avoid to
-// prevent overloading and having to use the HonorLabels param in Prometheus.
-//
-// - Information about the k8s pod being monitored:
-//		"pod" (name of the monitored k8s pod)
-//		"namespace" (k8s namespace of the monitored pod)
-// - Information about how promethus is gathering the metrics:
-//		"instance" (IP and port number being scraped by prometheus)
