Set up the kubernetes integration.
Do not disable timeouts on streaming connections.
Setting idle timeouts ensures that you are protected against denial-of-service attacks, inactive connections, and running out of ephemeral ports.
Note: By default,
--streaming-connection-idle-timeout is set to four hours, which might be too high for your environment. Setting this as appropriate would additionally ensure that such streaming connections are timed out after serving legitimate use cases.
Run the following command on each node:
ps -ef | grep kubelet. Verify that the
--streaming-connection-idle-timeout argument is not set to 0. If the argument is not present, and there is a Kubelet config file specified by
--config, check that it does not set
streamingConnectionIdleTimeout to 0.
If using a Kubelet config file, edit the file to set
streamingConnectionIdleTimeout to a value other than 0. If using command line arguments, edit the kubelet service file
/etc/systemd/system/kubelet.service.d/10-kubeadm.conf on each worker node and set the below parameter in
Based on your system, restart the kubelet service. For example:
systemctl daemon-reload systemctl restart kubelet.service
Long-lived connections could be interrupted.
--streaming-connection-idle-timeout is set to four hours.
