                                form of '-o Compression=yes -o
                                CompressionLevel=9', single option)
  -i, --identity-file FILENAME  Path to the private key file.  [default:
                                /root/.ssh/id_rsa]

So if you know server-id or IP, you can execute interactive SSH session with it. For example, if I want to connect to server 8cf8af12-89a0-477d-85e7-ce6cbe5f8a07:

root@7252bfd5947d:/# decapod-admin ssh server-id 8cf8af12-89a0-477d-85e7-ce6cbe5f8a07
