Changes pushed to git will be picked up by cyrus.works. Cyrus.works runs
Cyrus docker images[1]. Occasionally these will need to be updated.
Anyone with Git access can do this. I believe these were originally
created by Kolab but I’m happy to maintain the ones we need for
We cache some things that rarely change to improve the build
performance. This brings the build time down from about 34 minutes to
about 15. This cache is automatically cleared once a week.
We had plans to expose the ability to clear that cache via Slack and
those plans have been put on hold while we explore Travis CI.

We're currently gathering requirements for Cyrus test infrastructure.
Once we're satisfied with that list we'll see what technology we need
and create a plan.
