Dockerproxy

A little command line tool based on ncarlier/redsocks to proxy all running docker containers, without the need to configure anything inside of them.

Example

There are two ways of using this command line tool:

1. Recommended:
   • Configure the cli interactively for easier use later on (just type dockerproxy setup)
   • Use either dockerproxy up or dockerproxy down for starting or stopping the proxy.
2. For starting right away or usage in scripts:

   dockerproxy start --address company-proxy-address.com --port 8080

   You can use --network to specify a docker interface that should get proxied. (by default all networks get proxied)

Development and Debugging

1. Clone the repository and including the submodules (git submodule update --init --recursive)
2. Launch command with node --inspect-brk dockerproxy.js setup.
   1. Follow this guide.
   2. Launch Attach to Remote Debug Task in VSCode.
