Draining timeout in Ocean

The draining timeout (drainingTimeout) is a Flexera Ocean setting. It defines how long Ocean waits for a node to drain before the node is terminated.

• Default: 300 seconds

• A longer value gives your applications more time to complete a graceful shutdown.

Termination grace period in Kubernetes

The termination grace period (terminationGracePeriodSeconds) is a Kubernetes Pod‑level setting. It defines how long Kubernetes waits before stopping the pod’s processes.

• Default: 30 seconds

• Use this when your application needs more time to close connections or flush data.

How both settings work together

If a pod needs time to shut down, set its terminationGracePeriodSeconds value. Then, in Ocean, set a draining timeout that is equal to or greater than that value.

This ensures that Ocean does not terminate the node before Kubernetes finishes shutting down the pod.

Example

If a pod requires 600 seconds to close connections gracefully, set:

• terminationGracePeriodSeconds: 600

• Ocean drainingTimeout: greater than 600 seconds

This gives your workload enough time to shut down without interruption.
