I'm using Docker for Mac and for some reason the example proxy in examples/front-proxy cannot bind to 0.0.0.0:80 inside the container.

front-envoy_1  | [2020-06-08 21:04:27.772][7][critical][main] [source/server/server.cc:100] error initializing configuration '/etc/front-envoy.yaml': cannot bind '0.0.0.0:80': Permission denied

docker run --rm -p 80:80 nginx works fine.

So it makes me think something’s wrong with the docker-compose config. I unfortunately don't know enough to contribute.
