The problem with kubernetes is that containers just aren't quite enough.

You have an app which runs, now you want to put it in a container somewhere. Great. how do you build that container? Github actions. Great. How does that deploy your app to wherever it's running? Err... docker tag + docker push + ssh + docker pull + docker restart?

You've hit scale. You want redis now. How do you deploy that? Do you want redis, your machine, and your db in thre separate datacenters and to pay egress between all the services? Probably not, so you just want a little redis sidecar container... How does the app get the connection string for it?

When you're into home grown shim scripts which _are_ brittle and error prone, it's messy.K8s is a sledgehammer, but it's a sledgehammer that works. ECS is aws-only, and has its own fair share of warts. Cloud Run/Azure Container Apps are _great_ but there's nothing like those to run on DigitalOcean/Hetzner/whatever. So your choices are to use a big cloud with a simpler orchestartion, or use some sort of non-standard orchestration that you have to manage yourself, or just use k8s...
