Question
NGINX reverse proxy to Apache docker container
- Posted September 4, 2018

I’m trying to host several websites on my droplet. I’m to do that, I’m using NGINX (not container) as reverse proxy to Dockerized apps. One such app I’m using is the dockerized Mediawiki set to run on 0.0.0.0:8081.
Mediawiki container is based on php7.2-apache.
Nginx configuration :
server {
listen 443 ssl;
index index.php;
server_name my.website.com;
ssl_stapling on;
ssl_stapling_verify on;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://0.0.0.0:8081;
}
ssl_certificate /etc/letsencrypt/live/my.website.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/my.website.com/privkey.pem; # managed by Certbot
}
I run the application on port 8081, as can be seen by through docker ps -a
CONTAINER IMAGE PORTS
e40c9815d6cc mediawiki 0.0.0.0:8081 -> 80/tcp
I can access my.website.com, but it shows the default Apache Ubuntu default page. Accessing other pages and resources (index.php, /folder/index.php, images/pic.jpg) returns 404.
Testing the container with similar setup on my machine works. I think there maybe something up I didn’t get with the NGINX config.
Help?

I had the same issue not too long ago…
you don’t need to open or map 8081 to 80 port for access, just have 80 and 443 ports exposed inside container.
On your nginx container (if you are using docker-compose) add
depends_on:
- proxied_container
in your nginx.config
proxy_pass http://proxied_container:80;
This way nginx connects to container and its internal port and apache will handle everything else…
It’s simple. Just change the old configuration:
proxy_pass http://0.0.0.0:8081;
To this new one:
proxy_pass http://0.0.0.0:80;
The reason is, between container and Nginx in host server can’t communicate with published port. It just can communicate with the target port. 8081:80 (8081 is published port and 80 is target port).
Let say you have 8081:443, you must create the configuration with proxy_pass http://0.0.0.0:443; for Nginx listen to 443 port number. May this help.
I think this below link would be helpful for you
if after that you have questions ask about, thanks.
Hi @aerlaut!
Perhaps proxy_pass should be:
proxy_pass http://127.0.0.1:8081;
From what I understand is that, you want NGINX to listen on any IP address and network device in your server, at port 8081, (listen on 0.0.0.0:8081) and reroute that request to your local docker container on port 8081 (send to 127.0.0.1:8081).
Additionally what does nginx´s error log contains?
Hello @aerlaut ,
You could fix the problem related to not access the pages?
