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.

StackLight pods get stuck with the ‘NodeAffinity failed’ error

On a managed cluster, the StackLight Pods may get stuck with the Pod predicate NodeAffinity failed error in the Pod status. The issue may occur if the StackLight node label was added to one machine and then removed from another one.

The issue does not affect the StackLight services, all required StackLight Pods migrate successfully except extra Pods that are created and stuck during Pod migration.

To apply the issue resolution, remove the stuck Pods:

kubectl --kubeconfig <managedClusterKubeconfig> -n stacklight delete pod <stuckPodName>
