Dynamic proxy_pass in nginx to another pod in Kubernetes

Question

I\'m trying to create an nginx proxy that forwards requests to / to http://. I first tried the following:

Answer 1

After much research and trial and error I managed to solve this. First I changed the pod specification to:

spec:
  containers:
    - name: nginx
      image: "nginx:1.10.0"
      ports:
        - containerPort: 8080
          name: "external"
          protocol: "TCP"
    - name: dnsmasq
      image: "janeczku/go-dnsmasq:release-1.0.5"
      args:
        - --listen
        - "127.0.0.1:53"
        - --default-resolver
        - --append-search-domains
        - --hostsfile=/etc/hosts
        - --verbose

then I also had to disable the ipv6 for the resolver in nginx:

location ~ ^/(.+)$ {
        resolver 127.0.0.1:53 ipv6=off;
        set $backend "http://$1:80";
        proxy_pass $backend;
}

Then it works as expected!
