proxy-go

This is a simple service which takes requests and forwards them inside a K8s cluster (that's the initial goal). The motivation is to avoid doing port forward on every pod and reconnecting each time a pod dies. Relying on the services in front of those pods and, in the end, port forwarding just one pod.

Usage

kubectl port-forward -n <namespace> <proxy-go-pod> 8080:8080

Making a request to a service named echo at / is as follows:

curl http://localhost/echo

If the service is serving on a different port from 80, just add the port like this:

curl http://localhost/echo:<port>
