Ocata Series Release Notes¶

15.1.3¶

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

The task dropping the ironic 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_ironic 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 ironic_*_init_config_overrides variables which use the config_template task to change template defaults.

The ironic_neutron_provisioning_network_name and ironic_neutron_cleaning_network_name variable can be set to the name of the neutron network to use for provisioning and cleaning. The ansible tasks will determine the appropriate UUID for that network. Alternatively, ironic_neutron_provisioning_network_uuid or ironic_neutron_cleaning_network can be used to directly specify the UUID of the networks. If both ironic_neutron_provisioning_network_name and ironic_neutron_provisioning_network_uuid are specified, the specified UUID will be used. If only the provisioning network is specified, the cleaning network will default to the same network.

Added support for ironic-OneView drivers. Check the documentation on how to enable them.

The variables ironic_requirements_git_repo and ironic_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.
