Answer 1

Well you could achieve that by editing your /etc/hosts file and add the proper entry for your web host

1.1.1.1 web

Obviouslly you'll have to replace 1.1.1.1 with the web server's real ip address (a private one I suppose). Save the file and try again. Another workaround would be to replace in the config:

upstream docker-web {
    server web:8000;
}

with

upstream docker-web {
    server web-ip-address:8000;
}

If you'll go for the 2nd, don't forget to restart/reload nginx!
