debug kubelet not starting

Found an issue regarding this: https://github.com/kubernetes/kubernetes/issues/53333

Following the previous answer worked for me, but not the resolution offered in the linked issue.

So perhaps, following their suggestion of editing 90-kubeadm.conf (in place of 10-kubeadm.conf) would work

Things were solved by setting --fail-swap-on=false in the systemd script. Just make the modification on the file /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

Environment="KUBELET_SYSTEM_PODS_ARGS=--pod-manifest-path=/etc/kubernetes/manifests --allow-privileged=true --fail-swap-on=false"

then run systemctl daemon-reload and then systemctl restart kubelet
