I have a cloud build pipeline which builds and tries to deploy a multi-container service on Cloud Run.

The containers are:

• Frontend (exposed port 3000)
• Backend

I specified in the cloudbuild.yaml that frontend depends on backend:

    args:
      - beta
      - run
      - deploy
      - $_SERVICE_NAME
      - >-
        --container=frontend
      - >-
        --image=$_AR_HOSTNAME/$PROJECT_ID/cloud-run-source-deploy/$REPO_NAME/$_SERVICE_NAME-frontend:$COMMIT_SHA
      - --port=3000
      - --depends-on=backend

However, this doesn’t build because of error:

spec.template.spec.containers[0].depends_on: Dependent container ‘backend’ must have startup probe specified

And I don’t see a way to specify the startup probe in the docs.
