We have some minor automatic deployment of master branch to https://google-drive-photos-to-commons.toolforge.org/. You can find the setup in .travis.yml in https://github.com/tonythomas01/gdrive-to-commons.
We have to figure out how things would work since we moved to Gerrit. Probably there is some automatic Gerrit mechanisms we can use to some sort of post merge successfull jobs ? Never heard about it before, but would be worth investigating.
