GKE recently release Application Manager/Delivery addons for GKE. Application Deliver.

But currently, Application Manager/Delivery only supported Github.com and Gitlab.com. Is there any plan or release channel to support Gitlab Private? And are there any workarounds for this at the moment?

Initialize an application with Anthos Application delivery framework.
APP_NAME should conform to definitions of label and subdomain in DNS (RFC 1123: https://tools.ietf.org/html/rfc1123)

Usage:
  appctl init APP_NAME --app-config-repo [--deployment-repo] [--config-path] [flags]

Examples:
  # Initialize an app from scratch and create a remote app repository.
  appctl init myapp --app-config-repo github.com/myorg/myapp

  # Initialize an app from an existing repository.
  appctl init myapp -app-config-repo github.com/myorg/myapp

  # Initialize an app and customize the configuration path (default is ./config).
  appctl init myapp --app-config-repo github.com/myorg/myapp --config-path myappconfig

  # Initialize an app and customize the deployment repo.
  appctl init myapp --app-config-repo github.com/myorg/myapp --deployment-repo github.com/myorg/myapp-env


Flags:
      --app-config-repo string        The url of the application configuration repository. It should be in the form of "[https://]<github|gitlab>.com/<ORG or USER>/<REPO>".

      --config-path string            The relative directory that contains the application's kubernetes resource configurations. Default to "./config".
      --deployment-repo appctl init   the url of the deployment repository. It should be in the form of "[https://]<github|gitlab>.com/<ORG or USER>/<REPO>".
                                      If not provided, appctl init will use a default url in the form of "[https://]<PLATFORM>.com/<ORG or USER>/<APP_NAME>-deployment" where PLATFORM and ORG/USER are from --app-config-repo.
