Pass the request to another reverse proxy server

[geek-baba]

This is working great for most use cases I have except when I am trying to redirect to another proxy service running on my Kubernetes cluster. The K8s cluster is running nginx ingress (proxy) and it should route to specific app based on the domain name. However looks like when I am passing it via nginx proxy manager to my k8s cluster, the url/domain name is not passed to it.

So in simplest terms I want to pass domain name from one nginx server to another for further processing, is this something possible?

Try setting these in the advanced config:

    proxy_set_header Host            $host;
    proxy_set_header X-Forwarded-For $remote_addr;

It does not work, also it says on advance config page:

Nginx variables available to you are:

$server # Host/IP
$port # Port Number
$forward_scheme # http or https

@geek-baba Did you find any solutions for this?

I'm currently struggling to achieve the almost the same.
(For my case there is no kubernetes involved.)

Also found this issue #286 which seems to cover the same topic.

I had to separate the this proxy and k8s cluster to point to 2 different static IP's

i solved this problem by this way : https://stackoverflow.com/questions/37523615/dynamic-proxy-pass-in-nginx-to-another-pod-in-kubernetes

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!
