Hmmm, I don't have the experience to know if it's setup correctly or not. All I can do is watch it fail and then learn from my mistakes.
Is there a container "framework" that out of the box gives me all of " Blue/Green, canary, auto deploys, rollbacks..." so I don't have to guess if I'm doing it right?
You deal with all the headache of making your app stateless with a predictable API so that you can reap the benefits of a system like k8s, which can automatically manage all of it for you.
Similarly i'm a bit confused by your comment about SSH dying... in k8s you configure a readiness/liveness probe and behavior when the probe starts to fail. If SSH is an important thing for a given container, maybe the "liveness" probe is the command "ps aux |grep sshd". Then if it dies, the container can be pruned automatically.

https://github.com/aws/copilot-cli isn't ready for our use cases, but is more or less convox v2 built by AWS.
Edit: sadly it's still another layer onto aws/gcp/other... I'll pass again.
