Is there a way to delete multiplattform images which have untagged manifest images?

[Poeschl]

Currently I'm building images for two archs and therefore get 3 images per build. 1 "manifest" image and one image per architecture.
The manifest image gets tagged on build but this tag will be moved to a new image on a new build.

Now I'm searching for a option to remove all manifest images and the linked architecture images, but not the untagged images which are liked to the latest manifest image.

Is such a behavior possible at the current state of the action?

the option except_untagged_multiplatform is for this case

[Poeschl]

But doesn't that only exclude all multiplatform images from processing?

I think there is no news about this?
I'm currently using the except_untagged_multiplatform, but that prevent the deletion of all of my untagged images.

@Poeschl
I added some tests to verify this.
You can check from this line to the end of the file:

delete-untagged-ghcr-action/.github/workflows/test.yml

Line 171 in d3fb56f

add_temp_pkgs_multiple_platforms:

From what I see, the current code works as expected and I didn’t find any issues.
The action deletes the images/layers it is allowed to delete.

Note that I'm using docker inspect

delete-untagged-ghcr-action/clean_ghcr.py

Line 146 in d3fb56f

cmd = f"docker manifest inspect {image}"

to identify images that cannot be deleted — these may include images that are implicitly required.

If I missed something, please feel free to add a test that shows it.
As it stands, the current test confirms that 5 images are deleted as expected:

delete-untagged-ghcr-action/.github/workflows/test.yml

Line 217 in d3fb56f

if [[ "${{ steps.deleted-action.outputs.num_deleted }}" != 5 ]]; then

@Poeschl
I added a debug mode to v6.1

  env:
      ACTIONS_STEP_DEBUG: true

please share the logs if you have a bug
