ERROR: failed to create cluster: failed to generate kubeadm config content: failed to get kubernetes version from node: file should only be one line, got 0 lines

I have just installed KIND. Really having trouble creating a basic cluster because of this annoying error:

➜  Camunda kind create cluster --name camunda-local

Definitely will need more details than that to help troubleshoot. Can you fill in the rest of the prompts from the issue template:

---

• kind version: (use kind version):
• Runtime info: (use docker info or podman info):
• OS (e.g. from /etc/os-release):
• Kubernetes version: (use kubectl version):
• Any proxies or other special environment settings?:

---

It looks like you are using WSL. There are various issues that are commonly encountered, depending on how you have things set up. But if you can provide a little more detail, that might help narrow things down.

@stmcginnis done =)

We're going to need kind create cluster --retain && kind export logs && kind delete cluster, something with this host is causing the node containers to exit early most likely, given we fail to cat a static file right after starting them ...

I also just installed kind and I got this error

[stmcginnis]

I highly recommend using cgroupv2 instead of v1.
