Nginx proxy issue

I am running 2 containers on a server. They are both docker containers with the default nginx image.

I am trying to use Container1 as a reverse proxy for Container2.

Container1 is at ip address 172.17.0.3 Container2 is at ip address 172.17.0.4

when I curl Container1 i get the default Nginx homepage. I have edited the default homepage for container 2 so that it is just <p> HI </p> which is verified by a curl on the ip.

on my servers etc/hosts file, i added this line

172.17.0.3    testapp.net

My Container1's /etc/nginx/conf.d/default.conf is this

server {
    listen       80;
    server_name  localhost;
location / {
    root   /usr/share/nginx/html;
    index  index.html index.htm;
}

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html
#
error_page   500 502 503 504  /50x.html;
location = /50x.html {
    root   /usr/share/nginx/html;
}

}

server {
    listen 80;
    server_name testapp.net;

   location / {
         proxy_pass http://172.17.0.4

   }

}

when i do curl testapp.net i get the home page for Container1's nginx(the basic hello nginx html file) and am not directed to Container2. Why is this happening?

So your problem is that you just modify the /etc/hosts file on your server, not that in the docker container. The container has its own file system and own network, that's why your modification does not work.

The solution is to modify the /etc/hosts on your container during docker run. 

docker run --add-host testapp.net:172.17.0.3 your_image
