Improve documentation/examples for dynamic version ids

[chrisjohnson00]

Perhaps I'm too much of a n00b, but I'm finding it difficult to get this working with dynamic version ids.

My use case is that I build and push a docker container for every branch. The version (tag) on the container is the branch name. What I'd like to do is delete the versions which match the branch name when I delete the branch.

Here's what I've attempted

name: Delete branch tag

on:
  delete:
    branches: [ '**' ]

jobs:
  cleanup:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/delete-package-versions@v1
        with:
          package-version-ids: ${GITHUB_REF##*/}

But this results in an error:

Error: delete version mutation failed. Could not resolve to a node with the global id of '${GITHUB_REF##*/}'

The docs/examples don't give enough help/direction on how to get the version ids other than telling me to go look at the GH APIs. Is there a related action that I should use to get this, how have other people tackled deleting versions dynamically?

This action uses GraphQL which is not supported for containers:

GraphQL is not supported for containers or Docker images at ghcr.io.

Also, the Container Registry is still in beta.

I guess, the only solution for the moment is to manually delete our containers from the UI.

Otherwise, maybe try the following approach:

curl -s \
  -X DELETE \
  -H "Authorization: ${{ github.actor }} ${{ secrets.GITHUB_TOKEN }}" \
  -H "Accept: application/vnd.github.v3+json" \
  https://api.github.com/orgs/{org}/packages/container/{name}/versions/{version}

Having the same issue using delete-package-versions@v2. See https://github.com/actions/delete-package-versions/issues/66#issuecomment-1055207022
