OpenStack Keystone
==================

Keystone provides authentication, authorization and service discovery
mechanisms via HTTP primarily for use by projects in the OpenStack family. It
is most commonly deployed as an HTTP interface to existing identity systems,
such as LDAP.

From Kilo release Keystone v3 endpoint has definition without version in url

Sample pillars
==============

.. caution::

    When you use localhost as your database host (keystone:server:
    atabase:host), sqlalchemy will try to connect to /var/run/mysql/
    mysqld.sock, may cause issues if you located your mysql socket elsewhere

Enable ceilometer notifications

.. code-block:: yaml

    keystone:
      server:
        notification: true
        message_queue:
          engine: rabbitmq
          host: 127.0.0.1
          port: 5672
          user: openstack
          password: password
          virtual_host: '/openstack'
          ha_queues: true

Client-side RabbitMQ HA setup

.. code-block:: yaml

    keystone:
      server:
        ....
        message_queue:
          engine: rabbitmq
          members:
            - host: 10.0.16.1
            - host: 10.0.16.2
            - host: 10.0.16.3
          user: openstack
          password: pwd
          virtual_host: '/openstack'
        ....

Client-side RabbitMQ TLS configuration:

|

By default system-wide CA certs are used. Nothing should be specified except `ssl.enabled`.

.. code-block:: yaml

  keystone:
    server:
      ....
      message_queue:
        ssl:
          enabled: True

Use `cacert_file` option to specify the CA-cert file path explicitly:

.. code-block:: yaml

  keystone:
    server:
      ....
      message_queue:
        ssl:
          enabled: True
          cacert_file: /etc/ssl/rabbitmq-ca.pem

To manage content of the `cacert_file` use the `cacert` option:

.. code-block:: yaml

  keystone:
    server:
      ....
      message_queue:
        ssl:
          enabled: True
          cacert: |

          -----BEGIN CERTIFICATE-----
                    ...
          -----END CERTIFICATE-------

          cacert_file: /etc/openstack/rabbitmq-ca.pem


Notice:
 * The `message_queue.port` is set to **5671** (AMQPS) by default if `ssl.enabled=True`.
 * Use `message_queue.ssl.version` if you need to specify protocol version. By default is TLSv1 for python < 2.7.9 and TLSv1_2 for version above.

Enable CADF audit notification

Extra config params in keystone.conf (since Mitaka release)

.. code-block:: yaml

    keystone:
      server:
        ....
        extra_config:
          ini_section1:
            param1: value
            param2: value
          ini_section2:
            param1: value
            param2: value
        ....

Configuration of policy.json file

.. code-block:: yaml


    keystone:
      server:
        ....
        policy:
          admin_or_token_subject: 'rule:admin_required or rule:token_subject'

Setting up default admin project name and domain

.. code-block:: yaml


    keystone:
      server:
        ....
        admin_project:
          name: "admin"
          domain: "default"

Enhanced logging with logging.conf
----------------------------------

By default logging.conf is disabled.

That is possible to enable per-binary logging.conf with new variables:
  * openstack_log_appender - set it to true to enable log_config_append for all OpenStack services;
  * openstack_fluentd_handler_enabled - set to true to enable FluentHandler for all Openstack services.

Only WatchedFileHandler and FluentHandler are available.

Also it is possible to configure this with pillar:

.. code-block:: yaml

  keystone:
    server:
      logging:
        log_appender: true
        log_handlers:
          watchedfile:
            enabled: true
          fluentd:
            enabled: true

Usage
=====

Apply state `keystone.client.service` first and then `keystone.client` state.


Documentation and Bugs
======================

To learn how to deploy OpenStack Salt, consult the documentation available
online at:

    https://wiki.openstack.org/wiki/OpenStackSalt

In the unfortunate event that bugs are discovered, they should be reported to
the appropriate bug tracker. If you obtained the software from a 3rd party
operating system vendor, it is often wise to use their own bug tracker for
reporting problems. In all other cases use the master OpenStack bug tracker,
available at:

    http://bugs.launchpad.net/openstack-salt

Developers wishing to work on the OpenStack Salt project should always base
their work on the latest formulas code, available from the master GIT
repository at:

    https://git.openstack.org/cgit/openstack/salt-formula-keystone

Developers should also join the discussion on the IRC list, at:
