SSH Keys

---

RancherOS supports adding SSH keys through the [cloud-config]({{< baseurl >}}/os/installation/configuration/#cloud-config) file. Within the cloud-config file, you simply add the ssh keys within the ssh_authorized_keys key.

#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>

Please note that OpenSSH 7.0 and greater similarly disable the ssh-dss (DSA) public key algorithm. It too is weak and we recommend against its use.
