nginx timeout : timeout issues

I have having timeout problems with nginx. After looking through the config I see a problem

my docker container was started up with -e VIRTUAL_HOST=foo.bar.com docker ps gives me 971c26986bb3 [snip] 0.0.0.0:49156->3000/tcp my_app docker inspect 971c26986bb3 gives me

“NetworkSettings”: { “Bridge”: “docker0”, “Gateway”: “172.17.42.1”, “GlobalIPv6Address”: “”, “GlobalIPv6PrefixLen”: 0, “IPAddress”: “172.17.0.78”,

curl -H ‘Host: foo.bar.com’ http://localhost gives me a timeout curl -H ‘Host: foo1.bar.com’ http://localhost gives me a 503 Service Temporarily Unavailable (as expected)

curl -H ‘Host: foo.bar.com’ http://localhost:49156 gives me the expected data (so proving that the server is running on 49156->3000)

so, what am I doing wrong ?

# If we receive X-Forwarded-Proto, pass it through; otherwise, pass along the
# scheme used to connect to this server
map $http_x_forwarded_proto $proxy_x_forwarded_proto {
  default $http_x_forwarded_proto;
  ''      $scheme;
}

# If we receive Upgrade, set Connection to "upgrade"; otherwise, delete any
# Connection header that may have been passed to this server
map $http_upgrade $proxy_connection {
  default upgrade;
  ''      '';
}

@exadeci What does the Dockerfile in your local directory look like? I suspect it isn’t exposing any ports.

And…I missed that 😓. I exposed it on the docker-compose and now it works. Thank you
