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

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

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:

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:

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:

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:

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):

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

Region-aware service endpoints definition:

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:

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:

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.

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

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

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:

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.

  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:

keystone:
  server:
    logging:

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.

keystone:

server:

database:

x509:: enabled: True

You able to set custom certificates in pillar:

keystone:

server:

database:

x509:: cacert: (certificate content) cert: (certificate content) key: (certificate content)

Upgrades

Each openstack formula provide set of phases (logical bloks) 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.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)

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:
