Openstack compute resource flow

I'm trying to get a handle on how to provision standard cloud images on
OpenStack using Foreman. I keep getting VM's I cannot access because
Foreman has configured the instance with it's own SSH key, making it
impossible for me to ssh in using my own key. How can I specify additional
SSH key(s) to use (preferably a keypair that's already registered in
OpenStack)?

Surely there must be something I'm missing?

Thanks,
Bryce

You can use cloud-init to set some additional keys. An example I wrote
for Red Hat-based OS's. I need to come back and make this more
generic eventually…

Anyway, you can do something like this in the cloud init:

ssh_authorized_keys:

  • <%= @host.params['sshkey'] %>

And then use a Foreman parameter to set the SSH key.

Thanks much! Your example is exactly what I needed, and I can now get into
my Fedora 21 box. Now I'm off to try and figure out how to set up an
iPython notebook server using puppet classes + foreman.
