The smallest (15 MB) docker image with Tor and Privoxy on Alpine Linux.
docker run -d -P rdsubhas/tor-privoxy-alpine
curl --proxy localhost:8118 https://www.google.com
And that's it!
Known Issues
When running in interactive mode, pressing Ctrl+C doesn't cleanly exit. For now, run it in detached mode (-d). Calling docker stop cleanly exits though.
We're using testing versions of tor and runit in Alpine. Got to keep an eye on future builds, until those packages reach main in Alpine.
