Why are people still scared of k8s? At certain jobs thresholds, it is worth every ounce of effort to maintain it. Better yet, go managed.

People don't understand k8s and are thus hating. K8s is a wonderful tool for most things many teams need. It may not be useful for homelab type of stuff as the learning curve is steep, but for professional use it cannot be beat currently. Just a bunch of I know what I'm doing and don't need this complicated thing I don't understand. Pretty simple and especially in a forum such as HN where we all are "experts" and need to explain to ourselves, and crucially others, why we are right not to use k8s. Bunch of children really.

I honestly don't understand it either. Familiarity? K8s has like, what, 5 big concepts to know and once you are there the other concepts (generally) just build from there.

- Containers

- Pods

- Deployments

- Services

- Ingresses

There are certainly other concepts you can learn, but you aren't often dealing with them (just like you aren't dealing with them when working with something like docker compose).

Good luck fixing etcd when a major version upgrade breaks. It took all weekend to fight that fire when it happened to us.

Been there, done that, didn't get a t-shirt but got to yell at some people for setting up with undersized VMs and forgetting to note it anywhere.

Haven't had an issue once I fixed sizing.

Use managed k8s, problem solved.

That problem solved, but plenty of other things hiding in that 'simple' setup of just 5 concepts.

Which is why you don't lose your SRE/OPS team just because you k8s.

I'd say that if you aren't big enough to have dedicated SRE then k8s is not for you. However, it really only takes 1 or 2 people to manage pretty large clusters with 100s or 1000s of deployments.

That's where my company currently finds itself.
