This docker image sets up a mitmproxy which does SSL description.
CA data is stored in the /ca
volume which should be mounted somewhere persistent if you don't like adding a new certificate each time.
The port 8080
should be mapped to allow remote connections to the proxy server.
docker run -t -i -p 8080:8080 \
-v ~/.mitmproxy:/ca \
