Environment

Cause

The value for streaming-connection-idle-timeout parameter is not set in Kubelet configuration which is responsible for the maximum time a streaming connection can be idle before the connection is automatically closed. The value "0" indicates no timeout. As the value is not defined the command kubectl exec is timing out after 4 hours.

Resolution

Update the configmap and set the value of streamingConnectionIdleTimeout and verify if the change is successful.
