Two questions:
(1) I’m finding it difficult to manage the microk8s built in registry. What is the recommended way to list images in the registry, and delete the ones I no longer want? Searches yield people’s scripts that use the registry HTTP API via various scripts etc. Seems strange there is not a more well packaged mechanism for doing so?
(2) The HTTP API does not seem to work as expected. Is there a bug which causes it to break whenever an image has multiple tags?
curl 'http://host:32000/v2/oxcar-exe-boob/manifests/latest'
shows the manifest for that repo but
curl 'http://host:32000/v2/oxcar-overly-base/manifests/latest'
yields
{"errors":[{"code":"MANIFEST_UNKNOWN","message":"manifest unknown","detail":{"Name":"oxcar-overly-base","Revision":"sha256:e73504e5256d21ad5ede52f84545ae3fe6d19faed17f4869af4b701cdefe5ad7"}}]}
The logs from the registry pod don’t show anything unusual – they basically report the same error in “log” format.
This is on a microk8s on ubuntu 20.04 installed with snap, yesterday.

Here is the filesystem in the registry pod, which clearly shows the manifests are there?!
