Join cluster with ssh keys

[jimmy1987]

Is it possible to create / join a cluster using an ssh key instead of a password? I would like to turn off password auth for the root user but when trying to join a cluster over the webgui it requires to fill in the root password.

Hello,

For SSH sessions you can copy your public SSH key with the `ssh-copy-id` CLI tool and use the key exclusively for ssh sessions. You can also disable `PasswordAuthentication` (as described in `man sshd_config`), but this might potentially beak some cluster functionality like adding new nodes to the cluster.


On the other hand, when using the web UI, you cannot use a SSH session/key.
