Illumina Innovates with Rancher and Kubernetes
RancherOS supports adding SSH keys through the cloud-config file. Within the cloud-config file, you simply add the ssh keys within the ssh_authorized_keys key.
- 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.
Available as of v1.3
RancherOS supports changing the sshd port and IP, you can use these in the cloud-config file:
These settings are only designed for default console.
Because if you change sshd-config, restart the host will restore the default, the new configuration will not take effect.
For other consoles, all files are persistent, you can modify sshd-config by yourself.
