The working group to consider future tooling for continuous integration is making progress (see previous blog post J148 for more information). We're looking at and evaluating alternatives and learning of new needs within WMF.
If you have CI needs that are not covered by building from git in a Linux container, we would like to hear from you. For example, building iOS applications is difficult without a Mac/OS X build worker, so we're looking into what we can do to provide that. What else is needed?
We're currently aiming to make CI much more "self-serve" so that as much as possible can be done by developers themselves, without having to go via or through the Release Engineering team.
Our list of candidates include systems that are not open source or are "open core" (open source, but with optional proprietary parts). We will be self-hosting, and open source is going to be a hard requirement. "Open core" may be an acceptable compromise for a system that is otherwise very good. We want to look at all alternatives, however, so that we know what's out there and what's possible.
We track our work in Phabricator, ticket T217325.
