start proxy server on docker containers for http request from host

I have a docker container connected to a VPN, but sometimes i need to open a URL on browser for debug.

I cannot run the VPN on my host machine for security reasons, specifically i want to open the URL in my host machine and intercept request with BURP Suite, i already tried some “python proxy servers” from github to start a proxy on my docker machine and connect my host to it, without success.

Someone did something similar?. any ideas?

PD. sorry for my english. 🙂
