Changing Kubernetes' node-proxy tcp keepalive time : <p>How do I properly change the TCP keepalive time for node-proxy?</p>

<p>I am running Kubernetes in Google Container Engine and have set up an ingress backed by HTTP(S) Google Load Balancer. When I continuously make POST requests to the ingress, I get a 502 error exactly once every 80 seconds or so. <code>backend_connection_closed_before_data_sent_to_client</code> error in Cloud Logging, which is because GLB's tcp keepalive (600 seconds) is larger than node-proxy's keepalive (no clue what it is).</p>

<p>The logged error is detailed in <a href="https://cloud.google.com/compute/docs/load-balancing/http/" rel="noreferrer">https://cloud.google.com/compute/docs/load-balancing/http/</a>.</p>

<p>Thanks!</p>
