microk8s join ... --worker works, microk8s join ... does not

[itmitica]

Summary

I installed microk8s on multipass qemu vms on separate physical machines.

• Joining a multipass vm as worker from a physical machine to another is successful and the node appears in the cluster.
• Joining a multipass vm as control plane from a physical machine to another ends successful, but the node does not appear in the cluster and the microk8s on that multipass vm is now not reachable, some error about 127.0.0.7:16443.

Hi @itmitica, could you please provide more details in the setup (machines, VMs, networks, IPs, opened ports)? I suspect this has something to do with the datastore not being reachable from/to all nodes but I cannot be sure. Thanks

Hi @ktsakalozos ,

Two physical workstations, Ubuntu Live Server OS, 192.168.x.x IPs.
A multipass VM on each, with two different CIDRs.
Routes created on each physical machine for the multipass CIDRs on the other one.
No firewalls on physical or multipass VM.
