"Set up a reverse proxy and do blue-green deploys behind it." I think this already introduces enough complexity and edge cases to make reinventing the wheel a bad idea. There's a lot involved in doing it robustly. There are alternatives to Kubernetes (I prefer ECS/Fargate if you're on AWS), but trying to do it yourself to a production-ready standard sets you up for a lot of unnecessary yak shaving imho.
