Management of Solaris Zones

.. versionadded:: 2017.7.0

Below are some examples of how to use this state.
Lets start with creating a zone and installing it.

.. code-block:: yaml

    omipkg1_configuration:
      zone.present:
        - name: omipkg1
        - brand: ipkg
        - zonepath: /zones/omipkg1
        - properties:
          - autoboot: true
          - ip-type: exclusive
          - cpu-shares: 50
        - resources:
          - attr:
            - name: owner
            - value: Jorge Schrauwen
            - type: string
          - attr:
            - name: description
            - value: OmniOS ipkg zone for testing
            - type: string
          - capped-memory:
            - physical: 64M
    omipkg1_installation:
      zone.installed:
        - name: omipkg1
        - require:
            - zone: omipkg1_configuration
    omipkg1_running:
      zone.booted:
        - name: omipkg1
        - require:
            - zone: omipkg1_installation

A zone without network access is not very useful. We could update
the zone.present state in the example above to add a network interface
or we could use a separate state for this.

.. code-block:: yaml

    omipkg1_network:
      zone.resource_present:
        - name: omipkg1
        - resource_type: net
        - resource_selector_property: mac-addr
        - resource_selector_value: "02:08:20:a2:a3:10"
        - physical: znic1
        - require:
            - zone: omipkg1_configuration

Since this is a single tenant system having the owner attribute is pointless.
Let's remove that attribute.

.. note::
    The following state run the omipkg1_configuration state will add it again!
    If the entire configuration is managed it would be better to add resource_prune
    and optionally the resource_selector_property properties to the resource.

.. code-block:: yaml

    omipkg1_strip_owner:
      zone.resource_present:
        - name: omipkg1
        - resource_type: attr
        - resource_selector_property: name
        - resource_selector_value: owner
        - require:
            - zone: omipkg1_configuration

Let's bump the zone's CPU shares a bit.

.. note::
    The following state run the omipkg1_configuration state will set it to 50 again.
    Update the entire zone configuration is managed you should update it there instead.

.. code-block:: yaml

    omipkg1_more_cpu:
      zone.property_present:
        - name: omipkg1
        - property: cpu-shares
        - value: 100

Or we can remove the limit altogether!

.. note::
    The following state run the omipkg1_configuration state will set it to 50 again.
    Update the entire zone configuration is managed you should set the
    property to None (nothing after the :) instead.

.. code-block:: yaml

    omipkg1_no_cpu:
      zone.property_absent:
        - name: omipkg1
        - property: cpu-shares
