Deleting pipelines in Gitlab 11.6

Gitlab 11.6.0 just released, and one of the new features is deleting a pipeline. Why might you want to delete a little bit of history? Well, perhaps you have inadvertently caused some private information to be printed (a password). Or perhaps you left Auto DevOps enabled and ended up with a whole slew of useless failures. Either way you want to go and delete the pipeline in question and all of its output, artifacts, etc. Well here’s a quick ‘hack’ to achieve the goal.

You run it as ‘python delete-pipeline.py -t token -u url -g group -p project’ and it will list all the pipeline id’s. You can then run it with “-d ‘*’” to delete all of them, or “-d #,#,#…” to delete specific ones. You’ll likely want ‘pip install python-gitlab’ first.

Its a quick and dirty hack, but it worked for me. YMMV.
