And docker on Linux doesn’t support all the features that docker on Mac does. Specifically kubernetes.

You can dismiss this but if your dev shop is doing dev work that lands in a k8s cluster, it sure is nice to just have devs install docker desktop for Mac and they have a fully functioning k8s cluster that just works.

My whole company uses macs except me. I had to spend a bunch of time figuring out how to get a dev environment working on Linux. And it wasn’t easy as none of the out of the box k8s solutions support how we developed our build system. If I wasn’t a k8s admin from early versions of k8s I would have just given up.

No platform is perfect.

Kubernetes runs natively on Linux.

It sounds like your company built its dev tooling specifically around Docker for Mac. It's not surprising that it was a pain to replicate on Linux your company's work as a sole programmer.

But that doesn't mean that Linux doesn't support Kubernetes well. Linux is the primary target for k8s! It runs more efficiently and has better support than Kubernetes on Mac. Minikube has worked as a dev cluster on Linux long before Docker for Mac shipped a k8s dev cluster.

(I, too, have been involved with Kubernetes projects since the early days, and have built k8s tooling at fairly large companies.)

I never said kubernetes wasn’t supported on Linux. I said docker on Linux does not have that as a feature out of the box.

Go install docker desktop for Mac. Click a preference and you have kubernetes.

That is not the case in Linux. Can you install kind? Sure. Can you install minikube? Sure.

And define support? To give you a simple example, in minikube on Linux how do you make local images built by docker available in minikube?

It involves using dockerhub (rate limited) or running another local registry that you retag and push.

How about docker for Mac? No changes required at all, if the image is in the docker registry, it works in kubernetes

This is the exact type of retagging non sense that I hate in a dev workflow and is completely hacky.

So I solved it myself using k3s but I don’t think I have seen anyone else tackle it on Linux. Especially not minikube or kind

This is nonsense. We invested multiple man month this year to create a local k8s dev environment for our company. Our devs use MacOS and Linux. Me and my colleague evaluated various solutions for running k8s locally, all of which worked fine on Linux out of the box, while the process of setting them up for MacOS was riddled with issues (mostly around performance).

I am talking about out of the box features. Docker for Mac has kubernetes built in. Check a box and you have a k8s cluster. On Linux you need minikube, kind, or in my case, I built a custom k3s solution.
