The module uses exported resources to manage ssh keys and removes ssh keys that are not managed by puppet. This behavior is managed by the parameters ssh_key_ensure and purge_keys.

Manage user's ssh_authorized_keys

This works by passing the ssh::keys hash to the ssh_authorized_keys type with create_resources(). Because of this, you may specify any valid parameter for ssh_authorized_key. See the Type Reference for a complete list.

Sample usage:

Push authorized key "root_for_userX" and remove key "root_for_userY" through Hiera.

ssh::keys:
  root_for_userX:
    ensure: present
    user: root
    type: dsa
    key: AAAA...==
  root_for_userY:
    ensure: absent
    user: root
