Question 1

How to delete all old Docker images except the last 5 in GitHub Actions?

Accepted Answer

Use the action with package-type: 'container', min-versions-to-keep: 5, and set package-name to your image. For cross-repo access, add owner and a token with delete and read scopes. Examples in the README show similar scenarios for container packages.

Question 2

Delete Package Versions vs custom script for GitHub Packages cleanup – which is better?

Accepted Answer

This action is better for native GitHub integration and handling authentication automatically, but for deletions beyond 100 versions or custom logic outside GitHub Packages, a custom script might be necessary. The action simplifies common use cases but has limitations.

Question 3

What token permissions are needed for delete-package-versions?

Accepted Answer

If using package-version-ids, the token needs only the delete packages scope. Otherwise, it requires both delete and read packages scopes. For cross-repository access, some package types need Admin role, as detailed in the token input description.

Question 4

Can I ignore specific versions using regex when deleting?

Accepted Answer

Yes, use the ignore-versions input with a regex pattern to exclude versions from deletion. The README provides examples like '^(0|[1-9]\d*)\.0\.0$' to ignore major versions, and it works with min-versions-to-keep or num-old-versions-to-delete.

Question 5

Is there a limit to how many versions can be deleted at once?

Accepted Answer

Yes, the action deletes a maximum of 100 versions in one run, as stated in the README. For larger deletions, you may need to run the action multiple times or use alternative methods.

Question 6

Does this action work with GitHub Enterprise Server?

Accepted Answer

The README doesn't specify, but since it relies on GitHub's REST API, it should work with GitHub Enterprise Server if the API endpoints are available. However, you might need to verify token and endpoint compatibility in your environment.
