RancherOS supports adding SSH keys through the cloud-config file. Within the cloud-config file, you simply add the ssh keys within the
#cloud-config ssh_authorized_keys: - ssh-rsa AAA...ZZZ example1@rancher - ssh-rsa BBB...ZZZ example2@rancher
When we pass the cloud-config file during the
ros install command, it will allow these ssh keys to be associated with the rancher user. You can ssh into RancherOS using the key.
$ ssh -i /path/to/private/key rancher@<ip-address>
