Current Series Release Notes

18.0.0.0b1-235

New Features

  • It is possible to configure Glance to allow cross origin requests by specifying the allowed origin address using the glance_cors_allowed_origin variable. By default, this will be the load balancer address.

  • The service setup in keystone for glance will now be executed through delegation to the glance_service_setup_host which, by default, is localhost (the deploy host). Deployers can opt to rather change this to the utility container by implementing the following override in user_variables.yml.

    glance_service_setup_host: "{{ groups['utility_all'][0] }}"

  • Added variable glance_image_cache_stall_time to control glance cache time if needed. Defaults to 86400.

  • Added property protection configuration, managed with new variables: glance_property_protection_file_overrides (should be configured for a configuration to run, look in Default variables for an example), glance_property_protection_rule_format, glance_property_protection_file.

  • The role now supports using the distribution packages for the OpenStack services instead of the pip ones. This feature is disabled by default and can be enabled by simply setting the glance_install_method variable to distro.

  • Support separate oslo.messaging services for RPC and Notifications to enable operation of separate and different messaging backend servers in glance.

Upgrade Notes

  • Default value of glance_available_stores has changed. Now it is always should be represented as a list of mappings, where each item has following keys:

    • name (required)

    • type (required)

    • config (optional)

  • The glance v1 API is now removed upstream and the deployment code is now removed from this glance ansible role. The variable glance_enable_v1_api is removed.

Deprecation Notes

  • The variable glance_requires_pip_packages is no longer required and has therefore been removed.

  • Glance registry service has been finally removed

  • Variable glance_nfs_local_directory has been renamed to glance_images_local_directory to better reflect purpose of the variable. glance_nfs_local_directory remains for backwards compatability but will be removed in Zed release.

  • Variable glance_nfs_client has been replaced with glance_remote_client. New variable has new keys for defining mounts to cover wider range of supported filesystems. Compatability for glance_nfs_client has been kept until Zed release.

  • The rabbitmq server parameters have been replaced by corresponding oslo.messaging RPC and Notify parameters in order to abstract the messaging service from the actual backend server deployment. - glance_oslomsg_rpc_servers replaces glance_rabbitmq_servers - glance_oslomsg_rpc_port replaces glance_rabbitmq_port - glance_oslomsg_rpc_use_ssl replaces glance_rabbitmq_use_ssl - glance_oslomsg_rpc_userid replaces glance_rabbitmq_userid - glance_oslomsg_rpc_vhost replaces glance_rabbitmq_vhost - glance_oslomsg_notify_servers replaces glance_rabbitmq_telemetry_servers - glance_oslomsg_notify_port replaces glance_rabbitmq_telemetry_port - glance_oslomsg_notify_use_ssl replaces glance_rabbitmq_telemetry_use_ssl - glance_oslomsg_notify_userid replaces glance_rabbitmq_telemetry_userid - glance_oslomsg_notify_vhost replaces glance_rabbitmq_telemetry_vhost - glance_oslomsg_notify_password replaces glance_rabbitmq_telemetry_password

Other Notes

  • external_lb_vip_address was added to the default value for glance_cors_allowed_origin regardless of other variables.

  • Glance is using uWSGI when Ceph is used as a storage.
