This docker image allows you to use docker on a host without being bored by your corporate proxy.

You have just to run this container and all your other containers will be able to access directly to internet (without any proxy configuration).

Start the container like this:

docker run --privileged=true --net=host -d ncarlier/redsocks 1.2.3.4 3128

Replace the IP and the port by those of your proxy.

The container will start redsocks and automatically configure iptable to forward all the TCP traffic through the proxy.

If you want to add exception for an IP or a range of IP you can edit the whitelist file. Once edited you can replace this file into the container by mounting it:

docker run --privileged=true --net=host \
  -v whitelist.txt:/etc/redsocks-whitelist.txt \
  -d ncarlier/docker-redsocks 1.2.3.4 3128

Use docker stop to halt the container. The iptables rules should be reversed. If not, you can execute this command:

iptables-save | grep -v REDSOCKS | iptables-restore

Build the image with make.

Use make help to see available commands for this image.
