| ===== |
| Usage |
| ===== |
| |
| The Glance project provides services for discovering, registering, and |
| retrieving virtual machine images. Glance has a RESTful API that allows |
| querying of VM image metadata as well as retrieval of the actual image. |
| |
| Sample pillars |
| ============== |
| |
| .. code-block:: yaml |
| |
| glance: |

| source: http://cdn.download.cirros-cloud.net/0.3.1/cirros-0.3.1-x86_64-disk.img |
| public: true |
| audit: |
| enabled: false |
| api_limit_max: 100 |
| limit_param_default: 50 |
| barbican: |
| enabled: true |
| |
| The pagination is controlled by the ``api_limit_max`` and ``limit_param_default`` |
| parameters as shown above: |
| |
| * ``api_limit_max`` |
| Defines the maximum number of records that the server will return. |
| |
| * ``limit_param_default`` |
| The default ``limit`` parameter that applies if the request didn't define |
| it explicitly. |
| |

| |
| .. code-block:: yaml |
| |
| glance: |

| Configuring TLS communications |
| ------------------------------ |
| |
| .. note:: By default, system wide installed CA certs are used, so |
| ``cacert_file`` param is optional, as well as ``cacert``. |
| |
| - **RabbitMQ TLS** |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| message_queue: |
| port: 5671 |
| ssl: |
| enabled: True |
| (optional) cacert: cert body if the cacert_file does not exists |
| (optional) cacert_file: /etc/openstack/rabbitmq-ca.pem |
| (optional) version: TLSv1_2 |
| |
| - **MySQL TLS** |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| database: |
| ssl: |
| enabled: True |
| (optional) cacert: cert body if the cacert_file does not exists |
| (optional) cacert_file: /etc/openstack/mysql-ca.pem |
| |
| - **Openstack HTTPS API** |
| |
| Set the ``https`` as protocol at ``glance:server`` sections: |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| identity: |
| protocol: https |
| (optional) cacert_file: /etc/openstack/proxy.pem |
| registry: |
| protocol: https |
| (optional) cacert_file: /etc/openstack/proxy.pem |
| storage: |
| engine: cinder, swift |
| cinder: |
| protocol: https |
| (optional) cacert_file: /etc/openstack/proxy.pem |
| swift: |
| store: |
| (optional) cafile: /etc/openstack/proxy.pem |
| |
| Enable Glance Image Cache: |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| image_cache: |
| enabled: true |
| enable_management: true |
| directory: /var/lib/glance/image-cache/ |
| max_size: 21474836480 |
| .... |
| |
| Enable auditing filter (CADF): |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| audit: |
| enabled: true |
| .... |
| filter_factory: 'keystonemiddleware.audit:filter_factory' |
| map_file: '/etc/pycadf/glance_api_audit_map.conf' |
| .... |
| |
| Swift integration glance |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| enabled: true |
| version: mitaka |
| storage: |
| engine: swift,http |
| swift: |
| store: |
| auth: |
| address: http://keystone.example.com:5000/v2.0 |
| version: 2 |
| endpoint_type: publicURL |
| container: glance |
| create_container_on_put: true |
| retry_get_count: 5 |
| user: 2ec7966596504f59acc3a76b3b9d9291:glance-user |
| key: someRandomPassword |
| |
| Another way, which also supports multiple swift backends, can be |
| configured like this: |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| enabled: true |
| version: mitaka |
| storage: |
| engine: swift,http |
| swift: |
| store: |
| endpoint_type: publicURL |
| container: glance |
| create_container_on_put: true |
| retry_get_count: 5 |
| references: |
| my_objectstore_reference_1: |
| auth: |
| address: http://keystone.example.com:5000/v2.0 |
| version: 2 |
| user: 2ec7966596504f59acc3a76b3b9d9291:glance-user |
| key: someRandomPassword |
| |
| Enable CORS parameters: |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| cors: |
| allowed_origin: https:localhost.local,http:localhost.local |
| expose_headers: X-Auth-Token,X-Openstack-Request-Id,X-Subject-Token |
| allow_methods: GET,PUT,POST,DELETE,PATCH |
| allow_headers: X-Auth-Token,X-Openstack-Request-Id,X-Subject-Token |
| allow_credentials: True |
| max_age: 86400 |
| |
| Enable Viewing Multiple Locations |
| --------------------------------- |
| |
| If you want to expose all locations available (for example when you have |
| multiple backends configured), then you can configure this like so: |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| show_multiple_locations: True |
| location_strategy: store_type |
| store_type_preference: rbd,swift,file |
| |
| .. note:: The ``show_multiple_locations`` option is deprecated since |
| Newton and is planned to be handled by policy files *only* |
| starting with the Pike release. |
| |
| This feature is convenient in a scenario when you have swift and rbd |
| configured and want to benefit from rbd enhancements. |
| |
| Barbican integration glance |
| --------------------------- |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| barbican: |
| enabled: true |
| |
| Adding cron-job |
| --------------- |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| cron: |
| cache_pruner: |
| special_period: '@daily' |
| cache_cleaner: |
| hour: '5' |
| minute: '30' |
| daymonth: '*/2' |
| |
| |
| Image cache settings |
| -------------------- |
| |
| .. code-block:: yaml |
| |
| glance: |
| server: |
| image_cache: |
| max_size: 10737418240 |
| stall_time: 86400 |
| directory: '/var/lib/glance/image-cache/' |
| |
| |
| Client role |
| ----------- |
| |
| Glance images |
| |
| .. code-block:: yaml |
| |
| glance: |
| client: |
| enabled: true |
| server: |
| profile_admin: |
| image: |
| cirros-test: |
| visibility: public |
| protected: false |
| location: http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-i386-disk.img |
| |
| 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 |
| |
| glance: |
| server: |
| logging: |
| log_appender: true |
| log_handlers: |
| watchedfile: |
| enabled: true |
| fluentd: |
| enabled: true |
| ossyslog: |
| enabled: true |
| |
| Enable x509 and ssl communication between Glance and Galera cluster. |
| --------------------- |
| By default communication between Glance and Galera is unsecure. |
| |
| glance: |
| server: |
| database: |
| x509: |
| enabled: True |
| |
| You able to set custom certificates in pillar: |
| |
| glance: |
| server: |
| database: |
| x509: |
| cacert: (certificate content) |
| cert: (certificate content) |
| key: (certificate content) |
| |
