Help Post!!

Hello Experts,

I was deploying multinode openstack and during deployment i found some issues. Microk8s joining failed. While I tried to see the status of juju by running command “watch -n 2 -c juju status --color” I see microk8 join failed. Please have a look into the outputs as below,

Every 2.0s: juju status --color                                                                        osp-node1.gbpl.local: Thu Mar 28 13:26:51 2024

I had this problem too. I believe its due to your hosts not trusting a cert created by microk8s.

After the sunbeam cluster bootstrap --role control --role compute --role storage command is finised try running juju config microk8s skip_verify=True then add your workers.

If that doesnt fix the problem, you may want to dig into the logs to figure out why it failed.

Im totally not an expert on this at all btw so take my solutions with a grain of salt. Ive been struggling the last few days getting this to run but Im getting there slowly.

Good luck!
