Feature: Onionservice port different from exposed port

[langfingaz]

Current Situation

One can specify ONIONSERVICE_PORT in case a web service container has multiple ports exposed. This will result in the following line in torrc:

HiddenServicePort <ONIONSERVICE_PORT> <IP>:<ONIONSERVICE_PORT>

If one accesses the onion service, one has to append ":<ONIONSERVICE_PORT>" to the onion link.

Feature Request

It would be great to have two environment variables for web service containers that go into the generated torrc file:

• VIRTUAL_PORT
  • If set, use this port of to connect with the service. Useful if a service has more than one port exposed. If this is not set but just one port is exposed, use that port.
• ONIONSERVICE_PORT
  • If ONIONSERVICE_PORT is set, one can access the onionservice via this port. If it is not set, use the chosen virtual port instead.

Benefits

The above line in torrc would change to:

HiddenServicePort <ONIONSERVICE_PORT> <IP>:<VIRTUAL_PORT>

Even if VIRTUAL_PORT is e.g. 4040, one can still specify ONIONSERVICE_PORT=80 and visit the onion service just with the blank onion link.
