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 MCC). This means everything you need is in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Footnotes
- 0(1,2,3,4,5,6,7)
For the cluster support statuses description, refer to Cluster support statuses.
- 1(1,2,3,4,5,6,7)
Mirantis Container Cloud will update itself automatically as long as the release of each managed cluster has either supported or deprecated status in the new version of Container Cloud.
A deprecated cluster release becomes unsupported in one of the following Container Cloud releases. Therefore, we strongly recommend that you update your deprecated MOSK clusters to the latest supported version.
- 2(1,2,3,4,5,6,7,8)
The LTS duration of an OpenStack version is two years. For support timeline for different OpenStack versions, refer to OpenStack support cycle.
- 3(1,2,3,4,5,6,7,8)
The kernel version of the host operating system validated by Mirantis and confirmed to be working for the supported use cases. Usage of custom kernel versions or third-party vendor-provided kernels, such as FIPS-enabled, assume full responsibility for validating the compatibility of components in such environments.
- 4
The StackLight version is represented by the tag of the
stacklightHelm chart, which includes information about all StackLight components.
