How to run uWSGI and NGINX in different Docker containers

I've set up uWSGI and NGINX locally and my configurations have no issue serving web requests. However, when I containerize uWSGI and NGINX (in separate Docker containers) I can't seem to make a connection. My NGINX server configuration looks like this:

server {
    listen       80;
    server_name  localhost;
    location / {
        include uwsgi_params;
        uwsgi_pass uwsgi.app:9090;
    }
}

My uWSGI ini file looks like this:

[uwsgi]
socket = localhost:9090
module = uwsgi:app
processes = 4
threads = 2
master = true
buffer-size = 32768
stats = localhost:9191
die-on-term = true
vaccuum = true

I run the containers both in the same user-generated bridge network using the following for uWSGI docker run -p 9090:9090 --network main --name uwsgi.app -d uwsgirepo; and docker run -p 80:80 --network main --link uwsgi.app --name nginx.app -d nginxrepo for NGINX.

When I try to make a request on my local machine I get the following error message from the NGINX logs: '[error] 7#7: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 172.18.0.1, server: localhost, request: "GET /endpoint HTTP/1.1", upstream: "uwsgi://172.18.0.2:9090", host: "127.0.0.1"'

It doesn't look like it's ever connecting to uWSGI. Not sure where to go from here. Any thoughts?

Configure uwsgi to listen on 0.0.0.0 instead of localhost. That'll make it listen on all the containers interfaces. You are getting a connection refused because it's only listening on the uwsgi container's localhost, and not the container's eth0.
