New stable charms


New stable charm features

With each new feature, there is a corresponding example bundle in the form of a test bundle, and/or a section in the current guide (Charm Guide) that details its usage. Test bundles are located in the src/tests/bundles directory of the relevant charm repository (see all charm repositories).

manila charm: add support to configure scheduler default filters

The manila charm has a new configuration option scheduler-default-filters. This configures the scheduler_default_filters parameter in manila configuration file.

This is unset by default, so manila retains the default value for scheduler_default_filters. Those might change based on OpenStack release.

For more details see bug LP #1998200.

cinder charm: add support for Keystone audit middleware API logging

The cinder charm has a new configuration option audit-middleware. This option enables or disables Keystone audit middleware functionality that allows the user to audit API requests and configure their environment for CADF compliance (see keystone_audit_middleware). These audit events are written to /var/log/apache2/cinder_error.log.

This option is disabled by default to prevent log file bloat.

For more details see bug LP #1856555.
