Docker on Mac

Unfortunately Docker usage on mac is limited see:

• https://docs.docker.com/docker-for-mac/networking

This means the approach:

docker run -d  --name webserver nginx
docker inspect webserver | grep 'IPAddress":' 
            "IPAddress": "172.17.0.2",
                    "IPAddress": "172.17.0.2",

and then trying to connect via http://172.17.0.2 on port 80 won't work The workaround is to publish the port locally:

docker run -d -p 80:80 --name webserver nginx

http://localhost now works
