I'm trying to recreate a CI build to debug things locally. I've
followed the instructions under
https://doc.wikimedia.org/quibble/#reproducing-a-ci-build, but the
command for listing Docker images doesn't work. There are no images
with "quibble" in the name. Where can I find the available Quibble images?
Hello,
Quibble is not very user friendly. I started it during the 2017 Vienna
hackathon as a quick hack to unify the complicated stack of repos,
shell, python, Jenkins job into a single place. That has served to
reduce the CI complexity and made the jobs quite simpler.
Overall I can't say it is very pleasant to use as a human, there are a
few oddities such as:
- cleaning the dependencies and reinstalling everytime (use --skip-deps)
- misnamed options such as --skip-zuul to prevent refetching and doing a
git-clean of everything
- one need to set ZUUL_PROJECT to trigger the logic that runs
extension/skin tests
And more :)
I have sent a few patches recently to slightly improve it such as:
- automatically deleting the autogenerated LocalSettings.php instead of
having the MediaWiki installer to bail out after some minutes.
- Adding --change <gerrit change number> which retrieve from Gerrit the
metadata of the given change and initialize the ZUUL_* environment
variables (though I think one still has to set ZUUL_PROJECT to trigger
the proper logic ...)
Back on topic, the documentation about reproducing a CI build deserves
to be refreshed:
- the /v2/_catalog registry endpoint has evolved and is paginated
nowadays, see
https://distribution.github.io/distribution/spec/api/#listing-repositories
or look at which image is currently defined in CI (
https://gerrit.wikimedia.org/g/integration/config/+/refs/heads/master/jjb/mediawiki.yaml
).
Note that CI does a merge commit of the propose patch or patches against
the tip of the target branch. That is done by processes named
zuul-merger which exposes the resulting merges using git-daemon. Those
repositories are not publicly available, though they should be reachable
from a WMCS instance.
I am more than happy to assist and chat about Quibble. I will very
warmly welcome any help on that front :)
