I find that kubernetes yaml are a lot more complex than docker compose. And while I do, no, not everybody uses kubernetes.

I disagree with you on that. Kubernetes YAML is on the same level of complexity as docker compose and sometimes even easier.

But verbosity - yeah, kubernetes is absolutely super-verbose. Some 100-line docker-compose could easily end up as 20 yamls of 50 lines each. kubectl really needs some sugar to convert yamls from simple form to verbose and back.

We have about 30 services running in 4 environments, including dev. I desperately want a better kustomize that removes most of the boilerplate and adds linting (like, every process should have a ram limit, but no cpu limit). I estimate about 75% of the lines of YAML are redundant.

Have you thought about using jsonnet? It has a good library for k8s (https://jsonnet-libs.github.io/k8s-libsonnet/). I like how I don’t need to worry about white spaces and how I can use functions to reduce boilerplate. For an example environment: https://github.com/ThatFave/homelab

Is that intended to be a good example? There's still tons of duplication between the environments.

Kustomize eliminates the vast majority of the duplication (i.e. a unique fact about the cluster being expressed in more than one place), it's just the boilerplate that's annoying.

Not a good one, no. I am currently in the process of rewriting this, so that I eliminate duplicate code. The language has the potential, I am still in the process of learning. I also dislike boilerplate, but I think my example is still better than pure yaml.
