GitHub Action which allows use of private npm repositories in Google Artifact Registry.

See: Enabling keyless authentication from GitHub Actions

Example:

  - name: Authenticate Google Artifact Registry
    uses: sknups/authenticate-google-artifact-registry-action@v1
    with:
      workload_identity_provider: 'projects/123456789/locations/global/workloadIdentityPools/my-pool/providers/my-provider'
      service_account: 'my-service-account@my-project.iam.gserviceaccount.com'

Your project should have a .npmrc file in the root, e.g.:

@sknups:registry=https://europe-west2-npm.pkg.dev/sknups/npm/
@sknups-internal:registry=https://europe-west2-npm.pkg.dev/sknups/npm-internal/
//europe-west2-npm.pkg.dev/sknups/npm-internal/:always-auth=true
engine-strict=true

This action delegates to google-github-actions/auth@v2 to authenticate with Google Cloud.

That action writes a credentials file to the local filesystem, the location of which is stored in these environment variable:

• CLOUDSDK_AUTH_CREDENTIAL_FILE_OVERRIDE
• GOOGLE_APPLICATION_CREDENTIALS
• GOOGLE_GHA_CREDS_PATH

The credentials file will be deleted at the end of the job.

To delete the credentials file earlier, so it is not available to subsequent steps in the job, you can set erase_credentials:

  - name: Authenticate Google Artifact Registry
    uses: sknups/authenticate-google-artifact-registry-action@v1
    with:
      workload_identity_provider: 'projects/123456789/locations/global/workloadIdentityPools/my-pool/providers/my-provider'
      service_account: 'my-service-account@my-project.iam.gserviceaccount.com'
      erase_credentials: true

The environment variables will still be set, but their value will be a non-existent file.
