Kubernetes is a generalized solution to the problem - hence the complexity. Tools such as Docker Swarm were tailor fit to solve a particular application deployment and scaling problem - hence the simplicity.

I haven't looked in a while, but I recall at one time there being a utility that could take a Docker Swarm yaml and convert it to Kubernetes - Kompose? Has that matured into something useful?

On the subject of Kompose, frankly, I think a person looking to get into Kubernetes either knows how to convert what is essentially a docker-compose file to kubernetes manifests themselves, or they're going to struggle working with kubernetes to the point that no amount of "this is how you convert to this" tooling will save them. At the end of the day, you're working on kubernetes, so you need to know how to work with kubernetes. That might come off as gatekeeping to some, but it is an honest estimation of how much effort goes into productionizing workloads for kubernetes.

That's fair. It's usually worthwhile to suck it up and learn the basics of what it is you need to do.

Exactly. And I did a poor job of mentioning this in my previous message. But that perspective comes from trying to rely on Kompose to migrate my apps over to Kubernetes for me, and then falling utterly short in every aspect that makes Kubernetes inherently more powerful but also more complex than Swarm, such as in the domains of networking and storage. I ended up having to circle back to Kubernetes learning courses on Udemy, setting up a playground, making tons of mistakes, and accidentally becoming more proficient in Kubernetes than I had anticipated, just to get decent at deploying things to Kubernetes. And to be quite honest, I'm still learning about 6 years later. Lately less about storage and networking, and more with securing my workloads using securityContexts, runtime image scanners, etc etc. I'm at a point where I've written my own and helped contribute to Kubernetes operators, but I'm still learning how to effectively use all the tools Kubernetes gives you. So this took a bit of a tangent from the topic of Kompose, but it's all to basically say, "you'd be doing yourself a disservice to blindly rely on Kompose to get you into Kubernetes." In my opinion, of course.
