docker-tor-simple

License: MIT

Smallest minimal docker container for Tor network proxy daemon.

Suitable for relay, exit node or hidden service modes with SOCKS5 proxy enabled. It works well as a single self-contained container or in cooperation with other containers (like nginx and osminogin/php-fpm) for organizing complex hidden services on the Tor network.

The image is based on great Alpine Linux distribution so it is has extremely low size (less than 5 MB).

Star this project on Docker Hub 🌟 https://hub.docker.com/r/osminogin/tor-simple/

Ports

  • 9050 SOCKSv5 (without auth)

Volumes

  • /var/lib/tor data dir.

Getting started

Installation

Automated builds of the image are available on Docker Hub and is the recommended method of installation.

docker pull oppsig/tor

Alternatively you can build the image yourself.

docker build -t tor github.com/oppsig/tor

Quickstart

docker run -p 127.0.0.1:9050:9050 --name tor oppsig/tor

# or
docker-compose up

After start Tor proxy available on localhost:9050

❗Warning❗

Don't bind SOCKSv5 port 9050 to public network addresses if you don't know exactly what you are doing (better bind to localhost as in the example above).

Advanced usage

You can copy original tor config from container, modify and mount them back inside. Changing the configuration file is required for running Tor as exit node, relay or bridge. For some operation modes you need to expose additional ports (9001, 9030, 9051).

# Copy config
docker cp tor:/etc/tor/torrc /root/torrc

# ... modify torrc and run
docker run --rm --name tor \
  --publish 127.0.0.1:9050:9050 \
  --expose 9001 --publish 9001:9001 \ # ORPort
  --expose 9030 --publish 9030:9030 \
  --expose 9051 --publish 9051:9051 \
  --volume /root/torrc:/etc/tor/torrc:ro \
  oppsig/tor
