Hi guys I have spent hours trying to get two containers up & running correctly. Container 1: nginx reverse proxy Container 2: .net web api
Docker commands:
sudo docker network create --driver bridge tmpnetwork
sudo docker run -it -d --net tmpnetwork --rm -d -v /home/nginxfiles:/etc/nginx/conf.d --name revprox -p 80:80 nginx
sudo docker run -it -d --net tmpnetwork --name playapi -p 8081:80 2fe9c1e579aa
The web api is up & running. This works fine: curl http://localhost:8081/weatherforecast and http://example.com:8081/weatherforecast
conf file:
server {
listen 80;
listen [::]:80;
server_name example.com;
location / {
proxy_pass http://127.0.0.1:8081;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
I have tried: ufw disable
sudo docker logs --tail=10 -f
Gives error: failed (111: Connection refused) while connecting to upstream, client: xxx
How do I troubleshoot this? Br

Hi there,
As you’ve specified localhost/127.0.0.1 in your Nginx container, it is trying to connect on that port to itself.
Instead, as your containers are in the same network, you can specify the backend container name:
proxy_pass http://playapi;
That way the Nginx container will try to connect to the playapi
container directly over the tmpnetwork
network.
Your Nginx configuration would have worked if the Nginx service was running on the host itself rather than a separate container. Or if the Docker network was set to the host network rather than bridge
.
Let me know how it goes! Regards, Bobby
