Port forwarding with kubectl

If you want some kubernetes pod to forward all the traffic to you local machine, you can do this: 1. get pod id with

kubectl --kubeconfig <config> get po -lapp=<pod_label_app> -Lversion,cfg,infra-cfg

1	kubectl --kubeconfig <config> get po -lapp=<pod_label_app> -Lversion,cfg,infra-cfg

2. forward exact port from it to you localhost with

kubectl --kubeconfig <config> port-forward <pod-id> localhost_port:pod_port

1	kubectl --kubeconfig <config> port-forward <pod-id> localhost_port:pod_port

And you can request you localhost to reach pod on selected port.
