I don't really think you should promote these. The real way to perform clean update is using a load balancer, offloading instances for upgrade one at a time.

Also please people stop deploying using github. Package management & versioning IS a thing. > rsync -avz ./ user@remote:/home/user/web-app This is not an atomic update, meaning that you could end up loading modules from the new version from code of the older version. Use a new directory to upload the new files. > venv/bin/pip install -r requirements.txt You do not delete the old requirements, this is incrementally bloating the virtualenv. Just create a new one, virtualenv are designed to be created/removed quickly. > venv/bin/alembic upgrade head Huu, that's nice if you only have 1 instance to upgrade at a time. Otherwise it will just blow up.
