I find docker compose simple, and k8s quite complex. So if I can deploy a docker compose kind of project into it that would be nice.

And then on top of that it would handle or greatly assist with fault diagnosis, making sure the thing is highly available etc. There seems to be a lot of weird mistakes you can make with k8s which result in downtime of the app. If you have a full time dev ops person they can train and learn all those corner cases, but for a busy team that uses it and is doing other stuff it is too hard to stay on top of it. I have probably spent 8 hours in total seriously learning k8s! The rest is hacking.
