gcloud

GitHub Action which allows interacting with Google Cloud Platform.

Usage

To use gcloud in your workflow use:

- uses: actions-hub/gcloud@master
  env:
    PROJECT_ID: test
    APPLICATION_CREDENTIALS: ${{ secrets.GOOGLE_APPLICATION_CREDENTIALS }}
  with:
    args: info

You can also use gsutil from Google Cloud SDK package.

- uses: actions-hub/gcloud@master
  env:
    PROJECT_ID: test
    APPLICATION_CREDENTIALS: ${{ secrets.GOOGLE_APPLICATION_CREDENTIALS }}
  with:
    args: cp your-file.txt gs://your-bucket/
    cli: gsutil

You can also use kubectl from Google Cloud SDK package.

- uses: actions-hub/gcloud@master
  env:
    PROJECT_ID: test
    APPLICATION_CREDENTIALS: ${{ secrets.GOOGLE_APPLICATION_CREDENTIALS }}
  with:
    args: create deployment hello-server --image=gcr.io/google-samples/hello-app:1.0
    cli: kubectl

Secrets

APPLICATION_CREDENTIALS - To authorize in GCP you need to have a service account key. The recommended way to store the credentials in the secrets it previously encode file with base64. To encode a JSON file use: base64 ~/<account_id>.json. Or you can put a JSON structure to the secret.

PROJECT_ID - must be provided to activate a specific project.

Using access tokens

Alternatively, you can set the environment variable CLOUDSDK_AUTH_ACCESS_TOKEN to a valid OAUTH token; this allows the step to be used with Workload Identity Federation.

- id: google_cloud_auth
  name: Authenticate to Google Cloud
  uses: google-github-actions/auth@v1
  with:
    workload_identity_provider: 'projects/${{ secrets.gcp_project_number }}/locations/global/workloadIdentityPools/${{ secrets.workload_identity_pool }/providers/${{ secrets.workload_identity_provider }}'
    service_account: '${{ secrets.workload_identity_service_account }}@${{ secrets.gcp_project_name }}.iam.gserviceaccount.com'
    token_format: 'access_token'

- uses: actions-hub/gcloud@master
  env:
    PROJECT_ID: ${{ secrets.gcp_project_name }}
    CLOUDSDK_AUTH_ACCESS_TOKEN: '${{ steps.google_cloud_auth.outputs.access_token }}'
  with:
    args: info

Two important notes:

1. If CLOUDSDK_AUTH_ACCESS_TOKEN is set, it will override any other auth configuration
2. The gsutil command does not support the CLOUDSDK_AUTH_ACCESS_TOKEN variable; use gcloud storage to interact with GCS.

Inputs

args - command to run.

cli - (optional) command line tool you want to use. Defaults to gcloud, allowed values: gcloud, gsutil.

Version

For each new release of gcloud master branch is updated to the latest version. Also, the tag is creating with the same number as the gcloud version. If you want to always have the latest version of gcloud, use @master branch. But if you need some specific version of gcloud just use a specific tag. For example @271.0.0.
