If you'd like to add more Nodes to your MicroK8s Cluster, Configure like follows.

root@dlp:~# microk8s add-node From the node you wish to join to this cluster, run the following: microk8s join 10.0.0.30:25000/f99f1625c1b0d0ca7601a63cf9d6fba5/ff0519fe1876 Use the '--worker' flag to join a node as a worker not running the control plane, eg: microk8s join 10.0.0.30:25000/f99f1625c1b0d0ca7601a63cf9d6fba5/ff0519fe1876 --worker If the node you are adding is not reachable through the default interface you can use one of the following: microk8s join 10.0.0.30:25000/f99f1625c1b0d0ca7601a63cf9d6fba5/ff0519fe1876 |
