we’re currently setting up a new k8s cluster via RKE2 out of the Rancher UI and just hit this road block:
When running with 3 master servers, we obviously need some form of LB in front of them. After setting up the LB,
kubectl complains about the certificates:
Unable to connect to the server: x509: certificate is valid for 127.0.0.1, ::1, [...], not [...]
After looking around for a bit, I found the option
--tls-san when deploying the RKE2 Server manually, which allows to set additonal SANs the certs are valid for.
Is there a way to specify more SANs when deploying the new cluster from the Rancher UI?
Thanks for the help, highly appreciated!
