ssh_key_file
============

By default, ``tpaexec provision`` will use ``ssh-keygen`` to generate a
new SSH keypair for the cluster (into files named ``id_cluster_name``
and ``id_cluster_name.pub`` inside the cluster directory).

If you want to use an existing key instead, you can set ``ssh_key_file``
at the top level of config.yml to the location of an SSH private key
file. The corresponding public key must be available with an extension
of ``.pub`` at the same location:

.. code:: yaml

   ssh_key_file: ~/.ssh/id_rsa

(If this file does not already exist, it will be created by
``ssh-keygen`` during provisioning.)
