Joyent Cloud Module
===================

The Joyent Cloud module is used to interact with the Joyent cloud system.

Set up the cloud configuration at ``/etc/salt/cloud.providers`` or
``/etc/salt/cloud.providers.d/joyent.conf``:

.. code-block:: yaml

    my-joyent-config:
      driver: joyent
      # The Joyent login user
      user: fred
      # The Joyent user's password
      password: saltybacon
      # The location of the ssh private key that can log into the new VM
      private_key: /root/mykey.pem
      # The name of the private key
      keyname: mykey

When creating your profiles for the joyent cloud, add the location attribute to
the profile, this will automatically get picked up when performing tasks
associated with that vm. An example profile might look like:

.. code-block:: yaml

      joyent_512:
        provider: my-joyent-config
        size: g4-highcpu-512M
        image: centos-6
        location: us-east-1

This driver can also be used with the Joyent SmartDataCenter project. More
details can be found at:

.. _`SmartDataCenter`: https://github.com/joyent/sdc

Using SDC requires that an api_host_suffix is set. The default value for this is
`.api.joyentcloud.com`. All characters, including the leading `.`, should be
included:

.. code-block:: yaml

      api_host_suffix: .api.myhostname.com
