It's a developer tool made originally by google. Of course it's popular. Which isn't to say it's bad, it's just not much of a question as to why it's popular.

Kubernetes - kubernetes.io

Kubernetes is an open-source container-orchestration system for automating application deployment, scaling, and management. It was originally designed by Google, and is now maintained by the Cloud Native Computing Foundation.

Original author(s): Google

For me, and many others: infrastructure as code.

Kubernetes is very complex and took a long time to learn properly. And there have been fires among the way. I plan to write extensively on my blog about it.

But at the end of the day: having my entire application stack as YAML files, fully reproducible [1] is invaluable. Even cron jobs.

Note: I don't use micro services, service meshes, or any fancy stuff. Just a plain ol' Django monolith.

Maybe there's room for a simpler IAC solution out there. Swarm looked promising then fizzled. But right now the leader is k8s[2] and for that alone it's worth it.

[1] Combined with Terraform

[2] There are other proprietary solutions. But k8s is vendor agnostic. I can and have repointed my entire infrastructure with minimal fuss.

Yup, even monoliths can benefit from certain k8s tooling (HPAs, batch jobs, etc).

I've just started to look into it, but it seems like the project has been focusing on improving the onboarding experience since it has a reputation for being a huge pain to set up. Do you think it has gotten easier lately?

To draw anecdotally from my own experiences, its for two reasons:

1. It's simple to get started with, but complex enough to tweak to your needs in respect to simplicity of deployment, scaling and resource definition.

2. It's appealingly cloud-agnostic just at the time where multiple cloud providers are all becoming viable and competitive.

I think it's more #2 and #1; as always, timing is everything.

Out of curiosity, are you using terraform to deploy k8s, your app stack on k8s, or both?

Have you tried or considered Nomad (from the makers of Terraform)?
