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.

Addressed issues

The following issues have been addressed in the MOSK 22.4 release:

  • [25349][Update] Fixed the issue causing MOSK cluster update failure after an OpenStack controller node replacement.

  • [26278][OpenStack] Fixed the issue with l3-agent being stuck in the Not ready state and routers not being initialized properly during Neutron restart.

  • [25447][OpenStack] Fixed the issue that caused a Masakari instance evacuation to fail if an encrypted volume was attached to a node.

  • [25448][OpenStack] Fixed the issue that caused some Masakari instances to get stuck in the Rebuild or Error state when being migrated to a new OpenStack compute node during host evacuation. The issue occurred on OpenStack compute nodes with a large number of instances.

  • [22930][OpenStack] Fixed the issue wherein Octavia load balancers provisioning, and, occasionally, the listeners or pools associated with these load balancers got stuck in the ERROR, PENDING_UPDATE, PENDING_CREATE, or PENDING_DELETE state.

  • [25450][OpenStack] Implemented the capability to enable trusted mode for SR-IOV ports.

  • [25316][StackLight] Introduced projects filtering by a domain name for the default domain to fix the issue wherein a wrong project was chosen by name in case of multiple projects with the same names.

  • [24376][Ceph] Implemented the capability to parametrize the RADOS Block Device (RBD) device map to avoid Ceph volumes being unresponsive due to a disabled cyclic redundancy check (CRC) mode. Now you can use the rbdDeviceMapOptions field in the Ceph pool parameters of the KaaSCephCluster CR to specify custom RBD map options to use with StorageClass of a corresponding Ceph pool. For details, see Pool parameters.

  • [28783] [Ceph] Fixed the issue causing Ceph conditon stuck in absence of the Ceph cluster secrets information. If you applied the workaround to your MOSK 22.3 cluster before the update, remove the version parameter definition from KaaSCephCluster after the managed cluster update because the Ceph cluster version in MOSK 22.4 updates to 15.2.17.
