Kubernetes Hairpin-Proxy

Trying to get this to work on microk8s

https://github.com/compumike/hairpin-proxy

kubectl apply -f https://raw.githubusercontent.com/compumike/hairpin-proxy/v0.1.2/deploy.yml

kubectl get configmap -n kube-system coredns -o=jsonpath='{.data.Corefile}'

Still doesn't work

kubectl get svc -n ingress | grep ingress
output: nginx-ingress-microk8s-controller-86rjl.ingress.svc.cluster.local

kubectl edit deploy hairpin-proxy-haproxy -n hairpin-proxy
# Modify with below
   spec:
      containers:
      - env:
        - name: TARGET_SERVER
          value: nginx-ingress-microk8s-controller-86rjl.ingress.svc.cluster.local
        image: compumike/hairpin-proxy-haproxy:0.1.2


kubectl expose pod nginx-ingress-microk8s-controller-86rjl --type=NodePort --port=8080 -n ingress

Pods are up now

root@km1:~/src/hairpin-proxy# k get pods -n hairpin-proxy -o wide

Let's try and see if it works

root@km1:~/src/hairpin-proxy# k get svc --all-namespaces | grep hair
hairpin-proxy   hairpin-proxy                             ClusterIP   10.152.183.106   <none>        80/TCP,443/TCP           165mm

/ # host minimal.uvoo.io
minimal.uvoo.io has address 10.152.183.106

Works from outside host
