Migrate "App Engine Standard" away from"Container Registry?" (for "Artifact Registry")

Question

An email just went out about how this migration needs to happen, but it's not entirely clear how this affects App Engine Standard. I have a couple of small things running on that, and the only thing I see in the Container Registry is the app-engine-tmp folder.

Do we just delete that folder? Are new deployments from now on going to use Artifact Registry? More information would be great from anyone who might know!

Answer 1

The announced change does not affect any projects that are currently using Container Registry. Only projects not using Container Registry by May 2024 will be affected and they will use automatically use Artifact Registry for App Engine.

If you want to make a similar change to existing projects, you can follow the steps in https://cloud.google.com/artifact-registry/docs/transition/setup-gcr-repo Doing this will completely remove Container Registry usage from the project and use Artifact Registry for both gcr.io and pkg.dev urls (and App Engine)

You don't need to modify anything in your current project. The announcement said that once Container Registry is phased out, you can no longer host new Container Registry. But your existing Container Registry will remain and co-exist with the new Artifact Registry. All images will automatically be hosted in Artifact Registry which is just a Container Registry with additional feature and benefits. You can check this for more details.
