Workers

Метки: buildbot

A Workers corresponds to an environment where builds are executed. A single physical machine must run at least one Workers in order for Buildbot to be able to utilize it for running builds. Multiple Workers may run on a single machine to provide different environments that can reuse the same hardware by means of containers or virtual machines.

Each builder is associated with one or more Workers. For example, a builder which is used to perform macOS builds (as opposed to Linux or Windows builds) should naturally be associated with a Mac worker.

If multiple workers are available for any given builder, you will have some measure of redundancy: in case one worker goes offline, the others can still keep the Builder working. In addition, multiple workers will allow multiple simultaneous builds for the same Builder, which might be useful if you have a lot of forced or try builds taking place.

Ideally, each Worker that is configured for a builder should be identical. Otherwise build or test failures will be dependent on which worker the build is ran and this will complicate investigation of failures.
