Ocata Series Release Notes¶

15.1.21¶

For all ocata releases prior to OpenStack-Ansible 15.1.16, several of the magnum requirements were not constrained. This resulted in the kubernetes version changing over time unexpectedly, rather than by intention. Most recently this lack of constraint causes the repo build to fail when trying to build the magnum venv due to incompatible requirements.

The kubernetes version deployed with ocata is now constrained to version 2.0.0, matching the same version as deployed in all pike releases.

The magnum client interaction will now make use of the public endpoints by default. Previously this was set to use internal endpoints.

The keystone endpoints for instances spawned by magnum will now be provided with the public endpoints by default. Previously this was set to use internal endpoints.

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

The task dropping the magnum 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_magnum 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 magnum_*_init_config_overrides variables which use the config_template task to change template defaults.

The variables magnum_requirements_git_repo and magnum_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.
