Wait for those pods to show "2/2", the istio-proxy/envoy sidecar is part of that pod. # If "TPROXY", use iptables TPROXY to redirect to Envoy. The options range from fully-assembled Kubeflow stacks, to stacks that require some assembly. In Kubernetes these proxies as deployed as Sidecars in all participating pods (either manually or automatically using sidecar injection) and are programmed to intercept all inbound and outbound traffic through iptable redirection.
