Iam running the microk8s in ubuntu in no high availability i.e. there is a single node onto the same machine where it is installed. I updated the certificates and then i issue following command:
sudo microk8s leave
as it was advised that after upgrading the certificates nodes have to leave and rejoin.
It give following messages:
Generating new cluster certificates.
Waiting for node to start.
and then i stopped microk8s and then started again, the node appeared however all of my pods / namespaces are gone, how to recover?
