Getting Started With Parallels
==============================

Parallels Cloud Server is a product by Parallels that delivers a cloud hosting
solution. The PARALLELS module for Salt Cloud enables you to manage instances
hosted using PCS. Further information can be found at:

http://www.parallels.com/products/pcs/

* Using the old format, set up the cloud configuration at ``/etc/salt/cloud``:

.. code-block:: yaml

    # Set up the location of the salt master
    #
    minion:
        master: saltmaster.example.com

    # Set the PARALLELS access credentials (see below)
    #
    PARALLELS.user: myuser
    PARALLELS.password: badpass

    # Set the access URL for your PARALLELS host
    #
    PARALLELS.url: https://api.cloud.xmission.com:4465/paci/v1.0/


* Using the new format, set up the cloud configuration at
  ``/etc/salt/cloud.providers`` or
  ``/etc/salt/cloud.providers.d/parallels.conf``:

.. code-block:: yaml

    my-parallels-config:
      # Set up the location of the salt master
      #
      minion:
        master: saltmaster.example.com

      # Set the PARALLELS access credentials (see below)
      #
      user: myuser
      password: badpass

      # Set the access URL for your PARALLELS provider
      #
      url: https://api.cloud.xmission.com:4465/paci/v1.0/
      driver: parallels

.. note::
    .. versionchanged:: 2015.8.0

    The ``provider`` parameter in cloud provider definitions was renamed to ``driver``. This
    change was made to avoid confusion with the ``provider`` parameter that is used in cloud profile
    definitions. Cloud provider definitions now use ``driver`` to refer to the Salt cloud module that
    provides the underlying functionality to connect to a cloud host, while cloud profiles continue
    to use ``provider`` to refer to provider configurations that you define.

Access Credentials
==================
The ``user``, ``password``, and ``url`` will be provided to you by your cloud
host. These are all required in order for the PARALLELS driver to work.


Cloud Profiles
==============
Set up an initial profile at ``/etc/salt/cloud.profiles`` or
``/etc/salt/cloud.profiles.d/parallels.conf``:

.. code-block:: yaml

    parallels-ubuntu:
        provider: my-parallels-config
        image: ubuntu-12.04-x86_64

The profile can be realized now with a salt command:

.. code-block:: bash

    # salt-cloud -p parallels-ubuntu myubuntu

This will create an instance named ``myubuntu`` on the cloud host. The
minion that is installed on this instance will have an ``id`` of ``myubuntu``.
If the command was executed on the salt-master, its Salt key will automatically
be signed on the master.

Once the instance has been created with salt-minion installed, connectivity to
it can be verified with Salt:

.. code-block:: bash

    # salt myubuntu test.ping


Required Settings
=================
The following settings are always required for PARALLELS:


* Using the old cloud configuration format:

.. code-block:: yaml

    PARALLELS.user: myuser
    PARALLELS.password: badpass
    PARALLELS.url: https://api.cloud.xmission.com:4465/paci/v1.0/


* Using the new cloud configuration format:

.. code-block:: yaml

    my-parallels-config:
      user: myuser
      password: badpass
      url: https://api.cloud.xmission.com:4465/paci/v1.0/
      driver: parallels


Optional Settings
=================
Unlike other cloud providers in Salt Cloud, Parallels does not utilize a
``size`` setting. This is because Parallels allows the end-user to specify a
more detailed configuration for their instances than is allowed by many other
cloud hosts. The following options are available to be used in a profile,
with their default settings listed.

.. code-block:: yaml

    # Description of the instance. Defaults to the instance name.
    desc: <instance_name>

    # How many CPU cores, and how fast they are (in MHz)
    cpu_number: 1
    cpu_power: 1000

    # How many megabytes of RAM
    ram: 256

    # Bandwidth available, in kbps
    bandwidth: 100

    # How many public IPs will be assigned to this instance
    ip_num: 1

    # Size of the instance disk (in GiB)
    disk_size: 10

    # Username and password
    ssh_username: root
    password: <value from PARALLELS.password>

    # The name of the image, from ``salt-cloud --list-images parallels``
    image: ubuntu-12.04-x86_64
