Run Once Duration Override Operator overview

The Run Once Duration Override Operator enforces time limits on run-once pods to prevent tasks from running indefinitely and consuming cluster resources.

About the Run Once Duration Override Operator

The Run Once Duration Override Operator enforces time limits on run-once pods to prevent tasks such as builds and deployments from running indefinitely.

OpenShift Container Platform relies on run-once pods to perform tasks such as deploying a pod or performing a build. Run-once pods are pods that have a RestartPolicy of Never or OnFailure.

Cluster administrators can use the Run Once Duration Override Operator to force a limit on the time that those run-once pods can be active. After the time limit expires, the cluster tries to actively terminate those pods.

To apply the run-once duration override from the Run Once Duration Override Operator to run-once pods, you must enable it on each applicable namespace.

If both the run-once pod and the Run Once Duration Override Operator have their activeDeadlineSeconds value set, the lower of the two values is used.

Note

You cannot install the Run Once Duration Override Operator on clusters managed by the HyperShift Operator.
