This Docker image sets up Privoxy to be used as a proxy that can redirect traffic through the I2P or Tor networks.

Privoxy is a free non-caching web proxy with filtering capabilities for enhancing privacy, manipulating cookies and modifying web page data and HTTP headers before the page is rendered by the browser.

I2P is an anonymous network layer that allows for censorship-resistant, peer-to-peer communication by encrypting the user's traffic, and sending it through a volunteer-run network of roughly 55,000 computers distributed around the world.

Tor is a free and open-source software for enabling anonymous communication by directing Internet traffic through a free, worldwide, volunteer overlay network to conceal a user's location and usage from anyone performing network surveillance or traffic analysis.

To use Privoxy-I2P-Tor for improved privacy, follow these steps:

1. Clone and start the container:

   docker run -p 8118:8118 -p 4444:4444 -p 9050:9050 \
     docker.io/aguslr/privoxy-i2p-tor:latest
   

2. Change your Web browser's proxy settings to point to the appropriate proxy. Here we have 3 routing options:

   1. All traffic through Tor: use SOCKSv5 proxy with 127.0.0.1:9050.
   2. All traffic through I2P: use HTTP proxy with 127.0.0.1:4444.
   3. Only .i2p sites through I2P, .onion sites through Tor: use HTTP proxy with 127.0.0.1:8118.

Using a SOCKSv5 proxy is preferred as it provides added security.

To create more Tor instances, we can mount additional files with this command:

docker run -p 8118:8118 -p 4444:4444 -p 9050:9050 \
  -v "${PWD}/tor.ini:/etc/supervisor.d/tor.ini \
  -v "${PWD}/instances:/etc/tor/instances \
  docker.io/aguslr/privoxy-i2p-tor:latest

An example for tor.ini:

[program:tor1]
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
user=tor
command=/usr/bin/tor -f /etc/tor/instances/1/torrc

And an example for a Tor instance located in ./instances/1/torrc:

SocksPort 0.0.0.0:9051
Log notice stderr
DataDirectory /var/lib/tor/1
ExitNodes {es}

Instead of pulling the image from a remote repository, you can build it locally:

1. Clone the repository:

   git clone https://github.com/aguslr/docker-privoxy-i2p-tor.git
   

2. Change into the newly created directory and use docker-compose to build and launch the container:

   cd docker-privoxy-i2p-tor && docker-compose up --build -d
