description: >
  This template is designed to show the use of OS::Nova::KeyPair to generate a
  key that can then be used to ssh into a server instance. The simplest way to
  get the private key output into a file that you can then use for SSH is to run
    $ openstack stack output show -c output_value -f value <stack name> private_key > private-key.pem
  NOTE that you will need to use `chmod 600` on the file or SSH will refuse to use it.
