kubeadm init shows kubelet isn’t running or healthy [closed]

by

I faced similar issue recently. The problem was cgroup driver. Kubernetes cgroup driver was set to systems but docker was set to systemd. So I created /etc/docker/daemon.json and added below:

{
    "exec-opts": ["native.cgroupdriver=systemd"]
}

Then

 sudo systemctl daemon-reload
 sudo systemctl restart docker
 sudo systemctl restart kubelet

Run kubeadm init or kubeadm join again.
