Dynamic roster from terraform current state
===========================================

This roster module allows you dynamically generate the roster from the terraform
resources defined with the `Terraform Salt`_ provider.

It exposes all salt_host resources with the same attributes to the salt-ssh
roster, making it completely independent of the type of terraform resource, and
providing the integration using terraform constructs with interpolation.

Basic Example
-------------

Given a simple salt-ssh tree with a Saltfile:

.. code-block:: yaml

    salt-ssh:
      config_dir: etc/salt
      max_procs: 30
      wipe_ssh: True

and ``etc/salt/master``:

.. code-block:: yaml

    root_dir: .
      file_roots:
        base:
          - srv/salt
      pillar_roots:
        base:
          - srv/pillar
      roster: terraform

In the same folder as your ``Saltfile``, create terraform file with resources
like cloud instances, virtual machines, etc. For every single one of those that
you want to manage with Salt, create a ``salt_host`` resource:

.. code-block:: text

    resource &quot;salt_host&quot; &quot;dbminion&quot; {
      salt_id = &quot;dbserver&quot;
      host = &quot;${libvirt_domain.vm-db.network_interface.0.addresses.0}&quot;
      user = &quot;root&quot;
      passwd = &quot;linux&quot;
    }

You can use the count attribute to create multiple roster entries with a single
definition. Please refer to the `Terraform Salt`_ provider for more detailed
examples.
