Enable x509 and ssl communication between Ironic and Galera cluster.
---------------------
By default communication between Ironic and Galera is unsecure.

ironic:
  api:
    database:
      x509:
        enabled: True
  conductor:
    database:
      x509:
        enabled: True

You able to set custom certificates in pillar:

ironic:
  api:
    database:
      x509:
        cacert: (certificate content)
        cert: (certificate content)

      enabled: true
      version: pike
        cache:
          engine: memcached
          members:

Ensure nodes are in target state (available).
Starting from 1.11 API microversion newly-created node is moved to `enroll`
state. To move it to available the following client pillar might be used:

.. code-block:: yaml

  ironic:
    client:
      node_state_transition:
        enabled: true
        enroll_to_available:
          provision_state: 'enroll'
          pool_size: 5
          sleep_time: 10
          timeout: 15

Change default options using configmap template settings
========================================================

.. code-block:: yaml

  ironic:
    api:
      configmap:
        DEFAULT:
          enabled_drivers: pxe_ipmitool
          enabled_hardware_types: ipmi
          enabled_boot_interfaces: pxe
        api:
          host_ip: 0.0.0.0
          port: 6385
          max_limit: 1000
    conductor:
      configmap:
        DEFAULT:
          enabled_drivers: pxe_ipmitool
          enabled_hardware_types: ipmi
          enabled_boot_interfaces: pxe
        disk_partitioner:
          check_device_interval: 1
          check_device_max_retries: 20
        disk_utils:
          efi_system_partition_size: 200
          bios_boot_partition_size: 1

Upgrades
========

Each openstack formula provide set of phases (logical blocks) that will help to
build flexible upgrade orchestration logic for particular components. The list
of phases and theirs descriptions are listed in table below:

+-------------------------------+------------------------------------------------------+
| State                         | Description                                          |
+===============================+======================================================+
| <app>.upgrade.service_running | Ensure that all services for particular application  |
|                               | are enabled for autostart and running                |
+-------------------------------+------------------------------------------------------+
| <app>.upgrade.service_stopped | Ensure that all services for particular application  |
|                               | disabled for autostart and dead                      |
+-------------------------------+------------------------------------------------------+
| <app>.upgrade.pkgs_latest     | Ensure that packages used by particular application  |
|                               | are installed to latest available version.           |
|                               | This will not upgrade data plane packages like qemu  |
|                               | and openvswitch as usually minimal required version  |
|                               | in openstack services is really old. The data plane  |
|                               | packages should be upgraded separately by `apt-get   |
|                               | upgrade` or `apt-get dist-upgrade`                   |
|                               | Applying this state will not autostart service.      |
+-------------------------------+------------------------------------------------------+
| <app>.upgrade.render_config   | Ensure configuration is rendered actual version.     +
+-------------------------------+------------------------------------------------------+
| <app>.upgrade.pre             | We assume this state is applied on all nodes in the  |
|                               | cloud before running upgrade.                        |
|                               | Only non destructive actions will be applied during  |
|                               | this phase. Perform service built in service check   |
|                               | like (keystone-manage doctor and nova-status upgrade)|
+-------------------------------+------------------------------------------------------+
| <app>.upgrade.upgrade.pre     | Mostly applicable for data plane nodes. During this  |
|                               | phase resources will be gracefully removed from      |
|                               | current node if it is allowed. Services for upgraded |
|                               | application will be set to admin disabled state to   |
|                               | make sure node will not participate in resources     |
|                               | scheduling. For example on gtw nodes this will set   |
|                               | all agents to admin disable state and will move all  |
|                               | routers to other agents.                             |
+-------------------------------+------------------------------------------------------+
| <app>.upgrade.upgrade         | This state will basically upgrade application on     |
|                               | particular target. Stop services, render             |
|                               | configuration, install new packages, run offline     |
|                               | dbsync (for ctl), start services. Data plane should  |
|                               | not be affected, only OpenStack python services.     |
+-------------------------------+------------------------------------------------------+
| <app>.upgrade.upgrade.post    | Add services back to scheduling.                     |
+-------------------------------+------------------------------------------------------+
| <app>.upgrade.post            | This phase should be launched only when upgrade of   |
|                               | the cloud is completed. Cleanup temporary files,     |
|                               | perform other post upgrade tasks.                    |
+-------------------------------+------------------------------------------------------+
| <app>.upgrade.verify          | Here we will do basic health checks (API CRUD        |
|                               | operations, verify do not have dead network          |
|                               | agents/compute services)                             |
