Yo dawg, I heard you like port-fowards so I'm going to port-forward your port-forward.
Say you want to test something like maybe run something in minikube locally but connect to something running in the kube cluster.
Do your kube port foward
kubectl --context k8s-uw1-gcp port-forward prometheus-prometheus-server-7b6f9d99f8-m4vt6 9090
On your host system
socat -v TCP-LISTEN:9091,fork TCP:127.0.0.1:9090
Get your ip address on your host system
ip addr ... # Find the correct one ... 192.168.1.231
Then in minikube you can now reach the kube server:
~ # printf "GET / HTTP/1.0\r\n\r\n" | nc -vvvv 192.168.1.231 9091 192.168.1.231 (192.168.1.231:9092) open HTTP/1.0 302 Found Content-Type: text/html; charset=utf-8 Location: /graph Date: Wed, 23 May 2018 16:34:34 GMT Content-Length: 29 <a href="/graph">Found</a>. sent 18, rcvd 166
