Proxying container exposing multiple ports (but only one HTTP)

I’m trying to proxy a gitea container, which is exposing one SSH port and one HTTP port.

The README states:

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.

However even though I have set VIRTUAL_PORT to the exposed HTTP port, the service is marked as “down” in the generated default.conf of nginx:

server 172.17.0.11 down;

If I only expose the HTTP port the generator works as expected.

I have the same problem. I would like to run a gitea container behind the proxy. Running the gitea frontend is no problem with the config below. But the ssh port for git is not accessible through the gitea domain with this config.

The question is, how to add the port 22 to be exposed by the proxy, too?

Here’s my docker-composefile

Edit: with this config gitea frontend is exposed under code.example.de and ssh under host port 2222

I’m facing the same issue with phabricator docker-compose.
