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.

  4. Copy the downloaded kubeconfig to this machine.

  5. Run the following command:

    kubectl --kubeconfig <mgmtClusterKubeconfigPath> edit -n <projectName> cluster <managedClusterName>

  6. Edit the opened kubeconfig by removing the following lines:

    finalizers:
