Zed Series Release Notes

18.0.0.0b1-143

New Features

  • The service setup in keystone for gnocchi will now be executed through delegation to the gnocchi_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.

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

  • Implemented possibility to natively define gnocchi_incoming_driver separately from gnocchi_storage_driver. Default behaviour is that [incoming] is left unconfigured which means [storage] is used when gnocchi_incoming_driver and gnocchi_storage_driver are equal. Role will install incoming driver dependencies if required.

    To implement that following variables introduced:

    • gnocchi_storage_file_basepath

    • gnocchi_storage_swift_container_prefix

    • gnocchi_incoming_driver

    • gnocchi_incoming_file_basepath

    • gnocchi_incoming_swift_container_prefix

    • gnocchi_ceph_incoming_pool

    • gnocchi_ceph_incoming_username

  • Implemented variable gnocchi_metricd_workers that is designed to controll amount of gnocchi-metricd workers spawned. By default it is equal to number of CPU cores, but no more than 16 workers.

  • Variables gnocchi_storage_redis_url and gnocchi_incoming_redis_url were added to manage redis connection if it’s picked as an storage/incoming driver. Default value is redis://localhost:6379/ Please mention, that OpenStack-Ansible does not provide isntallation of Redis as of today.

Upgrade Notes

  • gnocchi_service_project_name now set by to service even for deployments involving Swift. Nowadays cielometer.middleware exclude service project by default, so no additional protection is required. In case you want to preserve current gnocchi_service_project_name, define it equal to gnocchi_swift in your user_variables.yml

  • Gnocchi migrated from usage of Apache mod_wsgi or native daemon to uWSGI daemon. This means, that some variables are not available and has no effect anymore, specifically * gnocchi_use_mod_wsgi * gnocchi_apache_* * gnocchi_ssl* (except gnocchi_ssl_external - it’s still in place) * gnocchi_user_ssl_*

    During upgrade process role will drop gnocchi_service_port from apache listeners (ports.conf) and gnocchi virtualhost, which by default means misconfigured apache service (since it won’t have any listeners) unless it’s aio build and this apache server is in use by other role/service. Apache server won’t be dropped from gnocchi_api hosts, so deployers are encoureged to remove it manually.

Deprecation Notes

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

Security Issues

  • The default TLS version has been set to TLS1.2. This only allows version 1.2 of the protocol to be used when terminating or creating TLS connections. You can change the value with the gnocchi_ssl_protocol variable.
