# Docker

Coder with Docker has the following advantages:

- Simple installation (everything is on a single box)
- Workspace images are easily configured
- Workspaces share resources for burst operations

## Requirements

- A single macOS or Linux box
- A running Docker daemon

## Instructions

1.  [Install and launch Coder](../install)

    Next, we export the `CODER_ADDRESS` and `CODER_ACCESS_URL` environment
    variables. We can use localhost for the Access URL since the workspaces
    all run on the same machine. `CODER_ADDRESS` is where coder server binds
    while `CODER_ACCESS_URL` is where it's accessed. We use `:7080` to bind
    to all interfaces.

    ```bash
    $ export CODER_ADDRESS=:7080
    $ export CODER_ACCESS_URL=http://localhost:7080
    $ coder server --address $CODER_ADDRESS --access-url $CODER_ACCESS_URL
    ```

1.  Run `coder login http://localhost:7080` in a new terminal and follow the
    interactive instructions to create your user.

1.  Pull the "Docker" example template using the interactive `coder templates init`:

    ```bash
    $ coder templates init
    $ cd docker
    ```

1.  Push up the template with `coder templates create`
1.  Open the dashboard in your browser (http://localhost:7080) to create your
    first workspace:

    <img src="../images/quickstart/docker/login.png">

    Then navigate to `Templates > docker > Create workspace`

    <img src="../images/quickstart/docker/create-workspace.png">

    Now wait a few moments for the workspace to build... After the first build,
    the image is cached and subsequent builds will take a few seconds.

1.  Your workspace is ready to go!

    Open up a web application or [SSH in](../ides.md#ssh-configuration).

1.  If you want to modify the Docker image or template, edit the files in the
    previously created `./docker` directory, then run `coder templates push`.
