I have my pod app container with istio proxy , if my pod (app container) is under going a restart or blue green via deployment upgrades we see that no traffic is lost this can be confirmed with
hey -c 50 -q 10 -z 320s https://staging.resource.api.sap/info --disable-keepalive ( disable keep alive ensure that each time a new connection is attempted )
However with system upgrades like images like k8s version upgrades, seem to cause new connections to fail for app container pods in. The issue hidden with the enabled keep-alive to see the issue we should add the --disable-keepalive.
Any suggestions how we can handle this situation with istio or envoy configurations ? to keep the connections do their jobs within the k8s upgrade time ?
