SSH Keys script

python util/ [-c CLUSTER [-i INSTANCE]] API_KEY URL
  • API_KEY is the value set in
  • URL is a URL pointing to the GWM server
  • CLUSTER is the identifier of a cluster
  • INSTANCE is the hostname of an instance

The GWM server URL has some flexibility in how it may be specified; HTTP and HTTPS are supported, as well as custom port numbers. The following are all valid URLs:

CLUSTER and INSTANCE are optional. Including them will narrow the list of users to either a Cluster or a VirtualMachine.

SSH Keys Ganeti hook

If you want your VMs to automatically copy the ssh keys from GWM, then you can use the included ssh keys ganeti hook found in util/hooks/ Copy that file onto every node in your cluster in the hooks directory for the instance definition you're using (i.e. ganeti-debootstrap). Copy and set the variables in util/hooks/sshkeys.conf into the variant config and/or the instance definition config file. Make sure that the hook is executable and all the variables are set include changing the API Key.
