Docker - Host bridge

docker_host_bridge.sh

#  https://forums.docker.com/t/accessing-host-machine-from-within-docker-container/14248/5
docker network create -d bridge --subnet 192.168.0.0/24 --gateway 192.168.0.1 dockernet

# Now each container can connect to the host under the fixed IP 192.168.0.1.
