    # Optional
    service-version: 3                          #default value : ""

Required

• service-account: service account key which will be used for authentication

  • Create a service account key
  • Encode service account key as base64 string
    • cat service-account-key.json | base64 on Linux or macOS
  • Store base64 value in GitHub secret

• project-id: GCP project id in which GAE service is available

• config-files: yaml files for the service or configurations you want to deploy

Optional

• service-version: version of the app that will be created or replaced by this deployment
• delete-previous-versions: set it to true to delete previous versions which are not receiving any traffic. If this is set to true then service-name is required
• service-name: name of the service of which previous versions needs to be deleted. Set it to default if service name is not mentioned in config file
• no-cache: deploy project without using cache. Takes longer, but useful in some cases. Set to true to not use cache
• debug: test action and check version details

• You cannot delete a version of a service that is currently receiving traffic
• This action will promote the deployed version to receive all traffic and stop previously running version --stop-previous-version
• If the version is running on an instance of an auto-scaled service in the App Engine Standard environment, using --stop-previous-version will not work and the previous version will continue to run because auto-scaled service instances are always running
