A Docker container for exposing applications as Tor onion services.
WARNING: This container makes non-anonymous, single-hop onion services.
https://hub.docker.com/r/spreadspace/onion-service/
Pass the ONION_HOST and ONION_PORT environment variables (the host and port
that should be exposed as an onion service) when starting the container.
Optionally, you can pass a hashed password as TOR_CONTROL_PW to restrict
access to little-t tor's control port.
