+You can disable support for HTTP/2 for the nginx-proxy container by passing the value `true` to the `NO_HTTP2` environment variable:

 ### 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.
