Description
Timeouts on streaming connections should be enabled. Setting idle timeouts ensures that the node is protected against Denial-of-Service attacks, inactive connections, and running out of ephemeral ports.
Choose one of the following remediation methods. For both methods, a restart of the Kubelet service is required.
Kubelet config file
- Add the following JSON to the
/etc/kubernetes/kubelet/kubelet-config.json file.
"streamingConnectionIdleTimeout": "4h0m0s"
Executable arguments
- Edit the Kubelet service file on each worker node and ensure the following parameters are part of the
KUBELET_ARGS variable string.
--streaming-connection-idle-timeout=4h0m0s
