Buildbot is shipped in two components: the buildmaster (called
buildbot for legacy reasons) and the worker. The worker component has far fewer requirements, and is more broadly compatible than the buildmaster. You will need to carefully pick the environment in which to run your buildmaster, but the worker should be able to run just about anywhere.
It is possible to install the buildmaster and worker on the same system, although for anything but the smallest installation this arrangement will not be very efficient.
