Ocata Series Release Notes¶

15.1.4¶

New variables have been added to allow a deployer to customize a barbican systemd unit file to their liking.

The task dropping the barbican systemd unit files now uses the config_template action plugin allowing deployers access to customize the unit files as they see fit without having to load extra options into the defaults and polute the generic systemd unit file with jinja2 variables and conditionals.

For the os_barbican role, the systemd unit TimeoutSec value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. The RestartSec value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using the barbican_*_init_config_overrides variables which use the config_template task to change template defaults.

The os_barbican role now supports the ability to configure whether apt/yum tasks install the latest available package, or just ensure that the package is present. The default action is to ensure that the latest package is present. The action taken may be changed to only ensure that the package is present by setting barbican_package_state to present.

The os_barbican role always checks whether the latest package is installed when executed. If a deployer wishes to change the check to only validate the presence of the package, the option barbican_package_state should be set to present.

The variables barbican_requirements_git_repo and barbican_requirements_git_install_branch have been removed in favour of using the URL/path to the upper-constraints file using the variable pip_install_upper_constraints instead.
