Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!
Starting with MOSK 25.2, the MOSK documentation set will cover all product layers, including MOSK management (formerly MCC). This means everything you need will be in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.
MOSK¶
Communications between Mirantis OpenStack for Kubernetes (MOSK) components are provided by the Calico networking. All internal communications occur through the Calico tunnel through the VXLAN or WireGuard protocols.
Note
Since Container Cloud 2.29.0 (Cluster releases 17.4.0 and 16.4.0), WireGuard is deprecated. If you still require the feature, contact Mirantis support for further information.
Caution
These ports are only used for in-cluster communications. Open them only to a trusted network and never at a perimeter firewall.
