# Add node group taints in a Managed Kubernetes cluster

Taints ([Taints and Tolerations](https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration/)) are labels that specify where pods cannot be scheduled.

1. In the [Control panel](https://my.selectel.ru/mks/), on the top menu, click **Products** and select **Managed Kubernetes**.

2. In the **Clusters** section, open the cluster page → **Cluster Composition** tab.

3. In the node group menu <MoreVerticalIcon />, select **Manage Taints**.

4. Enter the taint key.

5. Enter the taint value.

6. Select an effect:

   * NoSchedule — new pods will not be added and existing pods will continue to run;
   * PreferNoSchedule — new pods will be added if there are no other available slots in the cluster;
   * NoExecute — running pods without tolerations will be evicted.

7. Optional: to add an additional taint, click **Add** and repeat steps 4–6.

8. Click **Save**.
