So much of the benefit comes from adopting Kubernetes in in entirety? As in it could potentially bundle and replace commonly needed operation tools like secret management, etc?
I thought of something else rather important: k8s is truly "containers-first", IE containers are first-class in k8s. So it allowed me to get containers in production in a rock-solid manner without being a Docker expert. This is nice if you're seeking the advantages of promoting the exact same docker image from staging to production, for example.
What if your application is not necessarily architected for containers? Have you heard of existing systems being successfully migrated without significant changes in software architecture?
Hmm, if it's a monolith, it should be dockerizable without too much trouble. Yes I've migrated several legacy ish systems. Sometimes you have to take shortcuts and be "un-dockerish", for example by running nginx alongside your app server in the same image, but that's not a big deal really in practice.
