Question

A cluster operator adds the taint `maintenance=true:NoExecute` to node `worker-3` to prepare it for maintenance. A running pod on that node has the following toleration configured: `tolerations: - key: "maintenance" operator: "Equal" value: "true" effect: "NoExecute" tolerationSeconds: 300`. What happens to this pod after the taint is applied?

Accepted Answer

The pod continues running on worker-3 for 300 seconds, then is evicted.

Answer

The pod is evicted immediately because NoExecute taints do not honor tolerationSeconds.

Answer

The pod remains bound to worker-3 indefinitely because it tolerates the taint.

Answer

The pod is never scheduled again on any node until the taint is removed.
