Just a list of one-liners I keep using, forgetting and hunting for in history when building Envoy

Other Istio debugging commands:
Get the listener config for a particular pod kafka-0s' own Pod IP:
PODIP=$(kubectl get pod kafka-0 -o jsonpath="{.status.podIP}") && \
kubectl exec -it kafka-0 -c istio-proxy -- curl -s localhost:15000/config_dump | \
jq ".configs[] |\
select(.\"@type\"==\"type.googleapis.com/envoy.admin.v2alpha.ListenersConfigDump\").dynamic_active_listeners[] | \
select(.listener.name == \"${PODIP}_9094\")\

go install ./cmd/flagger/... && flagger -kubeconfig=$KUBECONFIG -metrics-server http://localhost:9090
kubectl -n test set image deployment/podinfo podinfod=stefanprodan/podinfo:2.0.1
