What happened:

Starting kind does not work anymore in my WSL2 environment.
kind create cluster --loglevel=debug --retain

leads to the following output:

Creating cluster "kind" ...
 ✓ Ensuring node image (kindest/node:v1.25.3) 🖼
 ✓ Preparing nodes 📦 📦 📦 📦
 ✓ Writing configuration 📜
 ✗ Starting control-plane 🕹️
ERROR: failed to create cluster: failed to init node with kubeadm: command "docker exec --privileged kind-control-plane kubeadm init --skip-phases=preflight --config=/kind/kubeadm.conf --skip-token-print --v=6" failed with error: exit status 1

It look familiar with #2731 but I'm not using a 5.17+ kernel.

Environment: WSL2, kind 0.18

uname -a
#Linux DUC-Lqp0bH3hPUL 5.15.90.1-microsoft-standard-WSL2 #1 SMP Fri Jan 27 02:56:13 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
$ kind version
#kind v0.18.0 go1.20.2 linux/amd64

3029766531.tar.gz

What you expected to happen:
kind starting a cluster without error.

How to reproduce it (as minimally and precisely as possible):
Get WSL2 (see below)

Use a Fedora 36 distribution (see below)

Start kind
kind create cluster

Anything else we need to know?:
Was working flawlessly with the same Fedora version 2 weeks ago. I suspect that WSL2 got a kernel update since then that might have triggered this issue.

✓ Ensuring node image (kindest/node:v1.25.3) 🖼

kind create cluster

Environment: WSL2, kind 0.18

Hmmm, these things don't match? KIND v0.18 defaults to a 1.26 image

Re: #2731, we intermittently get issues with users on odd Kernels that are missing cgroups functionality or have broken cgroups, I wouldn't expect this on fedora however, though last I checked WSL did typically involve a windows specific init instead of systemd (which would be setting up the cgroups).

I think this is #3165 (comment)

Check #3180, we have an issue with WSL2 1.2.0.0 that is fixed in a later WSL2 version.
