This is based on Jessie Frazelle's jess/privoxy image (github, blog post) with a few very minor tweaks (turned off debug logging, pinned alpine version, container is versioned).
Example usage: run a privoxy in a container and link to a tor socks proxy container:
docker run -d \ --restart always \ # the link inside the container must be named "torproxy" --network="host" \ -v /etc/localtime:/etc/localtime:ro \ -p 8118:8118 \ --name privoxy \ esurharun/privoxy
