Wallaby Series Release Notes

7.0.0

Upgrade Notes

  • The default value of [oslo_policy] policy_file config option has been changed from policy.json to policy.yaml. Operators who are utilizing customized or previously generated static policy JSON files (which are not needed by default), should generate new policy files or convert them in YAML format. Use the oslopolicy-convert-json-to-yaml tool to convert a JSON to YAML formatted policy file in backward compatible way.

Deprecation Notes

  • Use of JSON policy files was deprecated by the oslo.policy library during the Victoria development cycle. As a result, this deprecation is being noted in the Wallaby cycle with an anticipated future removal of support by oslo.policy. As such operators will need to convert to YAML policy files. Please see the upgrade notes for details on migration of any custom policy files.

6.0.0

Prelude

Introduce a CNI plugin for docker. The new CNI plugin will eventually replace kuryr-libnetwork (which is the current network plugin Zun is currently using for docker).

New Features

  • Introduce a CNI plugin for docker. In before, Zun was using libnetwork as the networking model for docker containers. Starting from this release, Zun introduces an alternative CNI plugin which implements the CNI networking model for docker containers. The new CNI plugin will become the default network plugin and the old libnetwork plugin will be deprecated.

Upgrade Notes

  • Deployers who are choosing CNI plugin don’t need to deploy kuryr-libnetwork and etcd.
