CoreOS forgets authorized_keys

  • Posted November 13, 2014

I have one working ssh key for CoreOS, created when creating the droplet. When I add a key via the web interface, it does not work, it is not added to authorized_keys . When I manually add a key to ~/.ssh/authorized_keys it works until a reboot, then the key is removed. How can I prevent this?

Edit: And how can I type an underscore without it making words italic?

On CoreOS, ~/.ssh/authorized_keys is an auto generated file by the update-ssh-keys command. In order to add a new key without it getting clobbered on reboot, you can do something like:

echo 'ssh-rsa AAAAB3Nza.......  key@host' | update-ssh-keys -a core
