First steps with docker....
Ziproxy only supports daemon-mode and inetd-mode. I ended up using daemon mode and
doing the old "tail -f" trick watching the ziproxy error log, in order to prevent the container from closing. I am looking for a better way to do this, but like I said, I am a docker newbie.
Start the fun with:
docker run -d -p 8080:8080 shinobit/ziproxy /usr/local/bin/startproxy
Configure your browser to use <docker-host-ip> port 8080 as your HTTP proxy and presto!
The ziproxy config files are located in /etc/ziproxy. There is a lot that can be fine-tuned; compression, passwords, ip address access restrictions, etc.
I chain ziproxy with an ad blocking proxy in order to keep my mobile data usage low. Enjoy.
