Cleanup of volumes and images

[hverlin]

Hi,
Do we expect the users to clean up the volumes, images, etc. over time?

I have a lot of gcl-*-tmp and gcl-*-build volumes (taking 100+GB) on my system after using the tool a few times.
There is some code to clean up the volumes

gitlab-ci-local/src/job.ts

Lines 527 to 535 in 2c088f2

	if (this._containerVolumeNames.length > 0) {
	try {
	for (const containerVolume of this._containerVolumeNames) {
	await Utils.spawn(["docker", "volume", "rm", `${containerVolume}`]);
	}
	} catch (e) {
	assert(e instanceof Error, "e is not instanceof Error");
	}
	}

here but not sure if it always runs properly when cancelling the command

I was thinking that maybe that it could show a warning if some unused volumes are still present at the very end of the run? Or add some commands in the README like suggesting running

docker volume rm $(docker volume ls -q --filter='name=gcl-')

from time to time?

Maybe related #861 (comment)

Most certainly not.

More or less everything should be cleaned.

Maybe I've introduced a bug.

I'll test, when I get to my laptop.

@hverlin I think i found my mistake, LOL 😆

Thank you! Was not sure if it was a bug or expected behavior as it might not be always possible to clean things properly
