kubeadm init kubelet complains default bind address already in use

kubeadm version 1.12.2

$ sudo kubeadm init --config kubeadm_new.config --ignore-preflight-errors=all

/var/log/syslog shows:

I have tried sudo systemctl stop kubelet and manually kill kubelet process but to no avail. Any advice and insights are appreciated.

Solution

  • I ditch kubeadm and use microk8s.
