Add node group taints in a Managed Kubernetes cluster

Last update: June 16 2026

Taints (Taints and Tolerations) are labels that specify where pods cannot be scheduled.

1. In the Control panel, on the top menu, click Products and select Managed Kubernetes.

2. Open the cluster page → Cluster Composition tab.

3. In the node group menu , 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.
