Honestly, k8s is super easy and very lightweight to run locally if you know the rights tools. There are a few good options but I prefer k3d. I can install Docker/k3d and also build a local cluster running in maybe 2 minutes. It’s excellent for local dev. Even good for production in some niche scenarios
I don't like the approach of piling more things on top of even more things to achieve the same goal as the base, frankly speaking. A "local" kubernetes cluster serve no purpose other than incredible complexity for little to no gain over a mere docker-compose. And a small cluster would work equally well with docker swarm.
A service, even made of multiple parts, should always be described that way. It's easy to move "up" the stack of complexity, if you so desire. Having "have a k8s cluster with helm" working as the base requirement sounds insane to me.
Yea I’m not a fan of helm either. In fact, I avoid charts when possible. But kustomize is great.
I feel the same way about docker compose. If it wasn’t already obvious, I’m biased in favor of k8s. I like and prefer that interface. But that’s just preference. If you like docker compose, great!
There’s one point where I do disagree however. There are scenarios where a local k8s cluster has a good and clear purpose. If your production environment runs on k8s, then it’s best to mirror that locally as much as possible. In fact, there are many apps that even require a k8s api to run. Plus, being able to destroy and rebuild your entire k8s cluster in 30s is wonderful for local testing.
Edit: typos
Seconding k3d (and, by extension, k3s). If you're in a market for sth suitable for more upstream-compliant clustering solution (k3s uses SQLite instead of etcd, iirc), RKE2 is also a great choice
