Total reclaimed space: 1.216GB

But podman system prune doesn't seem output the same info.

I poked at this for a little bit and got something maybe working (at least for reclaimed space for images) but I'm not sure on all of the specific requirements for this feature / if the maintainers want this.

reclaimed_size_output

I can open a PR after I clean up the code more but I would want to know more of the specific requirements such as:

  • What should the relaimed space metric include exactly? Images, Volumes, etc?
  • How should the data be presented. Currently prune reports seem to have a Size: output but it seems to be unformatted and just a byte count
  • Is it okay for the Podman project to pull in dependencies such as go-units from docker if the maintainers want human readable output.

Reclaimed space should be from containers/images and volumes.
It should be displayed in Human sizes. go-units is already imported, so that is not a problem.

Thanks for working on this.

@bugaevc I haven't forgotten about this issue. I'm currently trying to wrap up a different PR so I haven't been focusing on this, but I plan to.

Rework pruning to report reclaimed space
edf065b 
This change adds code to report the reclaimed space after a prune.
Reclaimed space from volumes, images, and containers is recorded
during the prune call in a PruneReport struct. These structs are
collected into a slice during a system prune and processed afterwards
to calculate the total reclaimed space.

Closes containers#8658

Made some decent progress on this. Not exactly sure the best way to test these changes and I might want to cleanup some of the prune helper functions that are no longer very useful.
