I am trying to setup a single-node cluster on my single board computer (non raspberry), running armbian (ubuntu bionic based kernel 4.19). I set up everything according to the official guides, but when I try to run kubeadm init it fails with timed out waiting for the condition when it's starting the control plane.

I read all the issues and questions about this problem, but nothing seems to be working for me. I also tried different kubernetes versions, but got the same results.

Here are all my logs (on this last run i tried k8 v1.12 but the results were the same as in v1.13):

[init] waiting for the kubelet to boot up the control plane as Static Pods from directory "/etc/kubernetes/manifests"

Unfortunately, an error has occurred:
        timed out waiting for the condition

This error is likely caused by:
        - The kubelet is not running
        - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
        - 'systemctl status kubelet'
        - 'journalctl -xeu kubelet'

Additionally, a control plane component may have crashed or exited when started by the container runtime.
To troubleshoot, list all containers using your preferred container runtimes CLI, e.g. docker.
Here is one example how you may list all Kubernetes containers running in docker:
        - 'docker ps -a | grep kube | grep -v pause'
        Once you have found the failing container, you can inspect its logs with:
        - 'docker logs CONTAINERID'
couldn't initialize a Kubernetes cluster

I just wanna learn kubernetes, so if anyone knows a different installation method other than kubeadm, that works on armv7, I would appreciate that too.
