Limitations

LimitationsΒΆ

The OpenContrail deployment in MCP includes the following limitations:

  • OpenContrail does not support tenant renaming due to architecture limitations.

  • OpenContrail does not support parallel addition and removal of rules to and from security groups.

  • By default, one worker of the contrail-api service is used. If needed, you can enable multiple workers in your Reclass cluster model, but this setting requires the keystone_sync_on_demand=false option that allows fixing the issue with the synchronization of the information about the OpenStack projects. Be aware that with such a configuration, you can start setting network entities in a newly created OpenStack project only one minute after this project is created.

    To set multiple workers with the keystone_sync_on_demand=false option, refer to MCP Operations Guide: Set multiple contrail-api workers.

  • Fixed in 2019.2.3 In the MCP Build ID 2019.2.0, by default, one worker of the contrail-api service is used. If needed, you can enable multiple workers in your Reclass cluster model, but this setting requires the keystone_sync_on_demand=false option that allows fixing the issue with the synchronization of the information about the OpenStack projects. Be aware that with such a configuration, you can start setting network entities in a newly created OpenStack project only one minute after this project is created.

    To set multiple workers with the keystone_sync_on_demand=false option, refer to MCP Operations Guide: Set multiple contrail-api workers.

    Starting from the MCP 2019.2.3 update, by default, six workers of the contrail-api service are used and you do not need the keystone_sync_on_demand=false option to be enabled for multiple workers. Therefore, the limitation described above is removed.
