New to django, so wanted to ask some questions that I didn't find good resources for:
1. If you deploy django apps using docker, do you run migrations before launching gunicorn/uwsgi etc within the docker image?
2. If you do, how does rolling migrations work? Won't the non-upgraded replicas start erroring if the new schema is not backward compatible?
3. How do you do non-backward compatible schema upgrades? Do you do it out of band from deployments? Do you shift traffic to a different cluster, and then zero traffic upgrade the whole cluster at once?
Thanks,
Sandip
