How can I cleanly remove a container image from the Google Container Registry?

I have pushed container images using gcloud docker push to the Google Container Registry. Two questions:

How do I cleanly remove a pushed container image from the registry? (I know I can remove a tag to an image and make it not accessible anymore.)

There are a bunch of Docker layers that an image brings with it. I want to remove all the unused layers with an image deletion.

Solution

  • UPDATE: You can now delete individual container images straight from the UI.

    1. Go to the Container Registry page.
    2. You should see a list of container images. Click the one you want to delete. Container Registry
    3. Select one or more tags, and click the delete button. Select and Delete images

    As of Nov 2015: There is no way to currently delete a single container image from the registry cleanly. Right now, it is basically all or nothing. The GCR team is working on this!

    Original Answer: I can't think of an easy way to delete individual images. You can delete ALL of the images by deleting the Cloud Storage bucket with gsutil rb gs://artifacts.<PROJECT-ID>.appspot.com. You can also use the storage browser and try to delete individual parts (https://console.developers.google.com/storage/browser/artifacts..appspot.com) but you would have to know the Docker hashes for each layer!
