# Note: This code is a stop-gap to erase Job Artifacts for a project. I HIGHLY recommend you leverage

@Tim-Schwalbe: Apologies, yes, I overlooked this case. I have amended the script to ignore artifacts_file, as this file seems to be contained in artifacts anyway.

I have improved my version a bit, it now automatically selects expired artifacts for deletion that (in my opinion) should be deleted in the first place, because they belong to jobs that were run on:

• merge requests that have been merged or closed;
• branches that have been merged.

It will also take a list of project ids as the last argument, making it easy to use in a cron job: Usage: {sys.argv[0]} <server> <token> <project id>...

@mikeller I suggest you write your script code in a gist, or even fork this one here and replace it with you python code =)

Each gist indicates which forks have activity, making it easy to find interesting changes from others.

@voiski: Good point, done: https://gist.github.com/mikeller/ee7a668a83e4b9bc61646bddb4a2ade6

New version that takes a GitLab group id as a parameter and then cleans up all repositories in the group: https://gist.github.com/mikeller/7034d99bc27c361fc6a2df84e19c36ff
