Perhaps there should be an "Orphan Cleanup" workflow section here: 
https://docs.pulpproject.org/pulpcore/workflows/index.html ?
It could also include information on the new "number of repo versions to 
retain" feature.

Just a thought,

Hi Experts,

I just start to use pulp_deb with docker pulp/pulp.I wonder How to clean the 
pulp database and release disk space?

I made several repositories, upload Deb packages, sycn remote repositories, 
while after I deleted all distributions, publications, remotes and 
repositories, there are still lots of content/packages. So how to remove all of 
them. Or, are there any methods to clear the whole environment and construct a 
pure new one(without any data/file)?

Pulp deduplicates content, so a given artifact can be shared among an arbitrary 
number of repositories. This is why deleting the repos doesn't on its own 
remove the content.

When a piece of content is no longer related-to any repositories, it's 
considered an 'orphan', and is available to be cleaned up. You can start the 
orphan-cleanup process with this API call:

  http DELETE http://<your-pulp-maching-and-port>/pulp/api/v3/orphans/

That starts a task that will remove all the unattached content.

Great question, hope this answers it for you!
Grant



Thanks
Xiao
