### Multiple Ports
If your container exposes multiple ports, nginx-proxy will default to the service running on port 80. If you need to specify a different port, you can set a VIRTUAL_PORT env var to select a different one. If your container only exposes one port and it has a VIRTUAL_HOST env var set, that port will be selected.
If your container exposes multiple ports, nginx-proxy will default to the service running on port 80. If you need to specify a different port, you can add VIRTUAL_HOST as <host>:<port>.
$ docker run -e VIRTUAL_HOST=foo.bar.com:8080 ...
If your container only exposes one port and it has a VIRTUAL_HOST env var set, that port will be selected.
