Hello there. I can’t for the life of me figure out why the designated leaf nodes can’t join the master node’s cluster? I’m following the documentation correctly from the ubuntu tutorial on microk8s and the official microk8s documentation page here: MicroK8s - Clustering with MicroK8s
I can issue the add node command on the master node fine, the join command I paste into one of the leaf nodes in order to join them into the cluster to become leaf nodes… fails with error code 500 but isn’t helpful. Could anyone point me in the right direction? I’m using Ubuntu server for ARM.
I am using carrier grade NAT, a 4G router with a 4G simcard inside; could this be the cause of the problem? I thought that it would at least join the cluster due to it not requiring WAN connectivity, as it’s on the same LAN (192.168.0.X) Thanks for your time.
The join command just returns ‘contacting cluster at 192.168.0.125’
‘failed to join cluster, error code 500’
The error is the same on all PI 3 Bs and PI 4, just much faster at executing on the PI 4.
