-------------------------------------
Summary: docker images cleanup in mock_cleanup.sh is done wrong
Key: OVIRT-1430
URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1430
Project: oVirt - virtualization made easy
Issue Type: Bug
Reporter: Daniel Belenky
Assignee: infra
We've decided that for now, we'll keep a cache of images coming from
centos|fedora official repositories. The cleanup is done by listing all the
images which are not coming from those repositories and removing them. The bug
is in the way we're listing and addressing images: we're addressing images by
image id's, which might be shared between several tags. For instance: if I have
a Dockerfile which builds a container from the official centos image and
doesn't really change the image, and then I tag the image with a different
name: tag, I'll get another reference for the official image, and the cleanup
will remove it.
Another issue that might come up, is that we do have an image, but its tag has
changed during the ran form 'latest' to something else. In this case, the
cleanup will just fail the job as it won't have find the image with the
different tag that have changed.
