ProfitBricks Cloud Module
=========================

The ProfitBricks SaltStack cloud module allows a ProfitBricks server to
be automatically deployed and bootstraped with Salt.

:depends: profitbrick >= 3.1.0

The module requires ProfitBricks credentials to be supplied along with
an existing virtual datacenter UUID where the server resources will
reside. The server should also be assigned a public LAN, a private LAN,
or both along with SSH key pairs.
...

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

.. code-block:: yaml

    my-profitbricks-config:
      driver: profitbricks
      # The ProfitBricks login username
      username: user@example.com
      # The ProfitBricks login password
      password: secretpassword
      # The ProfitBricks virtual datacenter UUID
      datacenter_id: <UUID>
      # SSH private key filename
      ssh_private_key: /path/to/private.key
      # SSH public key filename
      ssh_public_key: /path/to/public.key

.. code-block:: yaml

    my-profitbricks-profile:
      provider: my-profitbricks-config
      # Name of a predefined server size.
      size: Micro Instance
      # Assign CPU family to server.
      cpu_family: INTEL_XEON
      # Number of CPU cores to allocate to node (overrides server size).
      cores: 4
      # Amount of RAM in multiples of 256 MB (overrides server size).
      ram: 4096
      # The server availability zone.
      availability_zone: ZONE_1
      # Name or UUID of the HDD image to use.
      image: <UUID>
      # Image alias could be provided instead of image.
      # Example 'ubuntu:latest'
      #image_alias: <IMAGE_ALIAS>
      # Size of the node disk in GB (overrides server size).
      disk_size: 40
      # Type of disk (HDD or SSD).
      disk_type: SSD
      # Storage availability zone to use.
      disk_availability_zone: ZONE_2
      # Assign the server to the specified public LAN.
      public_lan: <ID>
      # Assign firewall rules to the network interface.
      public_firewall_rules:
        SSH:
          protocol: TCP
          port_range_start: 22
          port_range_end: 22
      # Assign the server to the specified private LAN.
      private_lan: <ID>
      # Enable NAT on the private NIC.
      nat: true
      # Assign additional volumes to the server.
      volumes:
        data-volume:
          disk_size: 500
          disk_availability_zone: ZONE_3
        log-volume:
          disk_size: 50
          disk_type: SSD

To use a private IP for connecting and bootstrapping node:

.. code-block:: yaml

    my-profitbricks-profile:
      ssh_interface: private_lan

Set ``deploy`` to False if Salt should not be installed on the node.

.. code-block:: yaml

    my-profitbricks-profile:
      deploy: False
