Tor proxy container based on alpine linux

A simple tor proxy based on alpine linux configured to listen on socks5 protocol:

socsk5://0.0.0.0:9150

The control port is set to 9050

Usage

Typical usecase of proxying another container's outgoing network traffic via a docker-compose.yml:

version: '2.4'
services:
    proxy:
        build: cminor/tor-proxy:latest
    curl:
        image: curlimages/curl:latest
        environment:
            ALL_PROXY: socks5://proxy:9150
        depends_on:
            - proxy

To test it works:

docker-compose run --rm curl curl https://check.torproject.org | grep Congratulations

Expected output:

  Congratulations. This browser is configured to use Tor.

*Note that in most cases (such as http requests from Golang) setting the environment variable HTTP_PROXY is enough. However curl does not read this variable (I haven't spent much time to investigate why) but using the ALL_PROXY will do the trick. See a;also this if interested for more information.

Customization

The image is very simple and should work out of the box for most use cases. If you would like to customize Tor you can provide your own torrc configuration file, either by volume sharing in your docker-compose.yml file:

volumes:
    ./my-torrc:/etc/tor/torrc

or extending this dockerfile and copying your own:

FROM cminor/tor-proxy:latest
COPY ./my-torrc:/etc/tor/torrc

Development

To build this image use the provided Makefile:

make build

To publish to dockerhub use:

make publish
