My rancher journey is going super-well – massive props to the team. This is a great product!
I’ve set up an HA cluster using the the rancher agent. This worked well, but I’ve done two things which seem to have broken DNS in particular:
- I had started rancher on one of the nodes, and since I wanted that node to also be a master, I needed to migrate it. I’ve migrated rancher elsewhere, re-run the agent on the machines, and things seem happy aside from DNS.
- I’ve rebooted one of the machines (but the other two have been up as-is).
My services are still available, but none of them can resolve domain names.
Any ideas of what to look for, or is this a kube question and I should be asking there?
