Kubernetes Failure Stories

I never used Docker Swarm (so can't compare), but I don't fully understand your point about Kubernetes cloud lock-in. Certainly there are important differences in networking, load balancing, persistent volumes, and other cloud features, but that's not something any platform can just hide/eliminate (e.g. think about AWS ELB/ALB/NLB vs Google Load Balancer). The Kubernetes concepts (Deployment, Ingress, Service) still work mostly the same for the user across clouds. Some other details like non-standardized Ingress annotations are obviously due to not having them agreed in Kubernetes core API (nginx ingress supports other annotations than say Google LB or Skipper).

The kubernetes folks describe a tentative solution to cloud lock-in here: https://kubernetes.io/docs/concepts/cluster-administration/f... OP isn't the only one with those concerns.

It would be nice when you can switch your cluster load from any of the cloud providers, or your own on-prem setup as you go. For instance, I could see people wanting to have a default small cluster on their on-prem setup, and be ready to scale on cloud when needed.

Kubernetes federation doesn’t really help with lock-in. Its for multi-cluster management. It’s also kind of stalled / going to be rethought - it has too many issues to be used at scale. Some may still like it of course.

There are two points of lock-in: beneath Kubernetes or on top of Kubernetes.

You still need to install and manage your cluster, so the low level lock-in of a distro is hard to avoid. What you may be looking for is kubeadm. https://kubernetes.io/docs/reference/setup-tools/kubeadm/kub...

It is the closest primitive to help standardize “here’s how to install and run a K8s cluster in a certified way”. It’s unfortunately incomplete.

As for what’s on top of Kubernetes, that will be an area ripe for completion and lock-in.

Federation is a solution for multi-cloud and hybrid cloud, which is a different problem than cloud portability.

Most of the kubernetes toolchain provides nice support for delineating the requirements from separate cloud providers, too. Compared to most alternatives, a little HELM magic to support hybrid cloud installations is a piece of cake.
