Restart SSH service in cloud-config

Archive RancherOS
1

Hi all,

I’m writing the /etc/ssh/sshd_config file via cloud-config. Specifically, I’m setting some trusted CA keys to allow SSH via signed certificates. I’ve had no issue getting the file modified, however I noticed that after RancherOS boots, the changes in /etc/ssh/sshd_config are not implemented until I login and manually do a:

system-docker restart console

So I tried adding that into a run command in my cloud-config:

runcmd:

  • system-docker restart console

However, when I boot with the cloud-config RancherOS loads all the way up until it’s about to launch the console and then freezes.

Is there another way I can restart the SSH daemon to ensure my changes are reflected when it boots up?

trying to find the same solution, maybe you have to rebuild rancher os image doing the following:

#cloud-config
ssh_authorized_keys:
    - ssh-rsa YOUR_HASH rancher
hostname: gil
write_files:
    - path: /etc/ssh/sshd_config
      owner: root
      permissions: '0600'
      content: |
          PermitRootLogin yes
          PasswordAuthentication yes

This worked perfectly well.
