When you're 1 man show (or tiny team) working on some web oriented application beyond POC level and beyond heroku (for whatever reason) — managing your CI, deployments/rollbacks, DBs etc. looks like a nightmare to me.
Just properly setting up and maintaining a small k8s cluster looks almost like a fulltime job.
I wonder how do your CI, deployment workflows look like?
Any particular tools, practices, guidelines, architecture patterns to reduce pain & timewaste?
How do you CI => deploy/rollback stateless instances? How do you manage your DBs and backups? Etc.
