Templates
Templates define the infrastructure underlying workspaces. Each Coder deployment can have multiple templates for different workloads, such as ones for front-end development, Windows development, and so on.
Coder manage templates, including sharing them and rolling out updates to everybody. Users can also manually update their workspaces.
Manage templates
Coder provides production-ready sample template, but you can modify the templates with Terraform.
# start from an example
coder templates init
# optional: modify the template
vim <template-name>/main.tf
# add the template to Coder deployment
coder templates <create/update> <template-name>
We recommend source controlling your templates.
Persistent and ephemeral resources
Coder supports both ephemeral and persistent resources in workspaces. Ephemeral resources are destroyed when a workspace is not in use (e.g., when it is stopped). Persistent resources remain. See how this works for a sample front-end template:
Resource | Type |
---|---|
google_compute_disk.home_dir | persistent |
kubernetes_pod.dev | ephemeral |
└─ nodejs (linux, amd64) | |
api_token.backend | ephemeral |
When a workspace is deleted, all resources are destroyed.
Parameters
Templates often contain parameters. In Coder, there are two types of parameters:
- Admin parameters are set when a template is created/updated. These values
are often cloud secrets, such as a
ServiceAccount
token, and are annotated withsensitive = true
in the template code.
User parameters are set when a user creates a workspace. They are unique to each workspace, often personalization settings such as "preferred region" or "workspace image".
