-----------------------------------
Summary: Use the Overlayfs mock plugin
Key: OVIRT-2165
URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2165
Project: oVirt - virtualization made easy
Issue Type: Epic
Components: mock_runner
Reporter: Barak Korren
Assignee: infra
mock has a plugin that allows it to store chroots on overlayfs instead of the
normal FS:
Details about the plugin can be found here:
https://github.com/rpm-software-management/mock/wiki/Plugin-Overlayfs
The plugin allows to quickly restore a chroot from a snapshot - this can at the
very least make the CI faster by 20 seconds, by saving time spent on extracting
the tarball from the chroot cache.
the plugin also adds a full snapshot and restore mechanism to mock, this can
allow us to make CI much faster by adopting something like the following scheme:
# Store and use snapshots of base-OS chroots (without modifications from
*.repos or *.packages files)
# Add the modifications from *.repos or *.packages files and snapshot them as
well.
This will make mock and CI run quite fast even if the *.repos or *.packages
files are changed.
Bottom line - this can essentially make mock run almost as fast as Docker
(Almost because one case will still be slow - when we don't have a base
snapshot and we need to build it, but if we decide that is an issue, we can
think up ways to pre-build it)
