=====
Usage
=====

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

.. code-block:: bash

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

Keystone fernet tokens for OpenStack Kilo release:

.. code-block:: yaml

    keystone:
      server:
        ...
        tokens:
          engine: fernet
          max_active_keys: 3

Keystone auth methods:

.. code-block:: yaml

    keystone:
      server:
        ...
        auth_methods:
        - external
        - password
        - token
        - oauth1
        ...

Keystone domain with LDAP backend, using SQL for
role/project assignment:

.. code-block:: yaml

    keystone:
      server:
        domain:
          external:
            description: "Testing domain"
            backend: ldap
            assignment:
              backend: sql
            ldap:
              url: "ldaps://idm.domain.com"
              suffix: "dc=cloud,dc=domain,dc=com"
              # Will bind as uid=keystone,cn=users,cn=accounts,dc=cloud,dc=domain,dc=com
              uid: keystone
              password: password

Use driver aliases for drivers instead of class path's:

.. code-block:: yaml

    keystone:
      server:
        domain:
          test:
            description: "Test domain"
            backend: ldap
            assignment:
              backend: sql
              driver: sql
            identity:
              backend: ldap
              driver: keystone.identity.backends.ldap.Identity
            ldap:
              url: "ldaps://idm.domain.com"
              ...

Using LDAP backend for default domain:

.. code-block:: yaml

    keystone:
      server:
        backend: ldap
        assignment:
          backend: sql
        ldap:
          url: "ldaps://idm.domain.com"
          suffix: "dc=cloud,dc=domain,dc=com"
          # Will bind as uid=keystone,cn=users,cn=accounts,dc=cloud,dc=domain,dc=com
          uid: keystone
          password: password

Using LDAP backend for default domain with
``user_enabled`` field emulation:

.. code-block:: yaml

    keystone:
      server:
        backend: ldap
        assignment:
          backend: sql
        ldap:
          url: "ldap://idm.domain.com"
          suffix: "ou=Openstack Service Users,o=domain.com"
          bind_user: keystone
          password: password
          # Define LDAP "group" object class and "membership" attribute
          group_objectclass: groupOfUniqueNames
          group_member_attribute: uniqueMember
          # User will receive "enabled" attribute basing on membership in "os-user-enabled" group
          user_enabled_emulation: True
          user_enabled_emulation_dn: "cn=os-user-enabled,ou=Openstack,o=domain.com"
          user_enabled_emulation_use_group_config: True

If the members of the group ``objectclass`` are user IDs
rather than DNs, set ``group_members_are_ids`` to ``true``.
This is the case when using ``posixGroup` as the group
``objectclass`` and ``OpenDirectory``:

.. code-block:: yaml

    keystone:
      server:
        backend: ldap
        assignment:
          backend: sql
        ldap:
          url: "ldaps://idm.domain.com"
          suffix: "dc=cloud,dc=domain,dc=com"
          # Will bind as uid=keystone,cn=users,cn=accounts,dc=cloud,dc=domain,dc=com
          uid: keystone
          password: password
          group_members_are_ids: True

Simple service endpoint definition (defaults to ``RegionOne``):

.. code-block:: yaml

    keystone:
      server:
        service:
          ceilometer:
            type: metering
            description: OpenStack Telemetry Service
            user:
              name: ceilometer
              password: password
            bind:
              ...

Region-aware service endpoints definition:

.. code-block:: yaml

    keystone:
      server:
        service:
          ceilometer_region01:
            service: ceilometer
            type: metering
            region: region01
            description: OpenStack Telemetry Service
            user:
              name: ceilometer
              password: password
            bind:
              ...
          ceilometer_region02:
            service: ceilometer
            type: metering
            region: region02
            description: OpenStack Telemetry Service
            bind:
              ...

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

.. note::

   * 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:

.. code-block:: yaml

    keystone:
      server:

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'

Manage ``os-cloud-config`` yml with ``keystone.client``:

.. code-block:: yaml

    keystone:
      client:
        os_client_config:
          enabled: true
          cfgs:
            root:
              file: /root/.config/openstack/clouds.yml
              content:
                clouds:
                  admin_identity:
                    region_name: RegioneOne
                    auth:
                      username: admin
                      password: secretpassword
                      user_domain_name: Default
                      project_name: admin
                      project_domain_name: Default
                      auth_url: "http://1.2.3.4:5000"

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 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

* ``openstack_ossyslog_handler_enabled``
   Set to true to enable ``OSSysLogHandler`` for all Openstack services

Only ``WatchedFileHandler``, ``OSSysLogHandler``, 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
          ossyslog:
            enabled: true

Usage
=====

#. Apply the :command:`keystone.client.service` state.
#. Apply the :command:`keystone.client` state.


Fernet-keys rotation without gluster
------------------------------------

In the future fernet keys supposed to be rotated with rsync+ssh instead of using glusterfs. By default it is assumed
that the script will run on primary control node (ctl01) and will rotate and transfer fernet keys to secondary
controller nodes (ctl02, ctl03). Following parameter should be set on cluster level:

keystone_node_role

and fernet_rotation_driver should be set to 'rsync'

By default this parameter is set to "secondary" on system level along with other parameters:
.. code-block:: yaml

  keystone:
    server:
      role: ${_param:keystone_node_role}
    tokens:
      fernet_sync_nodes_list:
        control02:
          name: ctl02
          enabled: True
        control03:
          name: ctl03
          enabled: True
      fernet_rotation_driver: rsync

Prior to running keystone salt states ssh key should be generated and its public part should be placed on secondary controllers.
It can be accomplished by running following orchestration state before keystone states:

salt-run state.orchestrate keystone.orchestrate.deploy

Currently the default fernet rotation driver is a shared filesystem

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

You able to set custom certificates in pillar:
server:
  database:
    x509:
      enabled: True

keystone:
  server:
    database:
      x509:
        cacert (certificate content)
        cert (certificate content)
        key (certificate content)

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:
