Versions

kubeadm version v1.28

kubeadm version: &version.Info{Major:"1", Minor:"28", GitVersion:"v1.28.0", GitCommit:"855e7c48de7388eb330da0f8d9d2394ee818fb8d", GitTreeState:"clean", BuildDate:"2023-08-15T19:27:34Z", GoVersion:"go1.20.7", Compiler:"gc", Platform:"linux/amd64"}

Environment:

• Kubernetes version v1.28.0
• Cloud provider or hardware configuration: n/a
• OS (e.g. from /etc/os-release): Linux
• Kernel (e.g. uname -a): n/a
• Container runtime (CRI) (e.g. containerd, cri-o): n/a
• Container networking plugin (CNI) (e.g. Calico, Cilium): n/a
• Others: node swap desired

What happened?

https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/ states “You MUST disable swap in order for the kubelet to work properly.”

What you expected to happen?

Now that (Linux) swap support in the kubelet is beta, I expect that kubeadm provides (beta) support for running Linux nodes with swap enable.

How to reproduce it (as minimally and precisely as possible)?

Read installing kubeadm

Anything else we need to know?

If the support is there and it's just the web page that is stale, it's OK to transfer this issue to k/website.
