Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Known issues¶

This section describes the patch-related known issues with available workarounds.

OpenStack upgrade failure¶

Fixed in MOSK 23.1.3

The OpenStack upgrade to Yoga fails due to the delay in the Cinder start.

Workaround:

Follow the openstack-controller logs from the OpenStackDeployment container. When the controller is stuck on checking health for any OpenStack component, verify the Helm releases statuses:

helm3 --namespace openstack list

Example of a system response:

NAME                     NAMESPACE       REVISION        UPDATED                                 STATUS          CHART
openstack-cinder         openstack       111             2023-04-30 20:49:08.969450386 +0000 UTC failed          cinder-0.1.0-mcp-4241

If there is a release in the failed state, roll it back:

helm3 --namespace openstack rollback openstack-cinder
