This action prepares the environment to build Docker images with the Depot CLI. It does this by making the following changes:

1. Installs the depot CLI in the GitHub Actions environment.
2. Installs Depot as a Docker CLI plugin (docker depot ...)
3. Sets the Depot plugin as the default Docker builder (docker build ...)
4. Installs a Buildx shim so that docker buildx build is forwarded to the Depot plugin.

Download and use the latest version of the CLI:

jobs:
  job-name:
    steps:
      - uses: depot/use-action@v1
      - run: depot ...

The depot CLI needs to resolve a project ID to build images. This can be from a DEPOT_PROJECT_ID environment variable, a depot.json file, or the --project CLI flag. To set the global DEPOT_PROJECT_ID, use the project input:

jobs:
  job-name:
    steps:
      - uses: depot/use-action@v1
        with:
          project: abc123xzy

The depot CLI also needs to authenticate with Depot to connect to remote builders. We recommend using OIDC trust relationships to authenticate, as these do not require configuring a static access token:

jobs:
  job-name:
    permissions:
      contents: read
      id-token: write
      # optional, if you need to push to ghcr.io
      packages: write

    steps:
      - uses: depot/use-action@v1

If you do need to provide an API token, you can set the DEPOT_TOKEN environment variable with the token input:

jobs:
  job-name:
    steps:
      - uses: depot/use-action@v1
        with:
          token: ${{ secrets.DEPOT_TOKEN }}

• project (optional) - A string representing the project ID to use for builds. This can be overridden by the DEPOT_PROJECT_ID environment variable or the --project CLI flag.
• token (optional) - A string representing the API token to use for authentication. This can be overridden by the DEPOT_TOKEN environment variable.
• version (optional) - A string representing the version of the Depot CLI to install (e.g. 1.2.3). The default value is latest which will install the latest available version. Can also specify a semver version range selector (e.g. 0.x.x).
• shim-buildx (optional) - A boolean representing whether to install the Buildx shim. The default value is true.
