docker execute command in image code example

Example 1: docker interactive shell

docker exec -it [containerid/name] [shell]

#Example
docker exec -it fa80b69 bash
#if its an apline container use "sh" instead of "bash"

Example 2: docker run all port mapping

docker run --network host
When running using --network host there is no need to map the ports.
All the docker container ports will be available since the network host mode 
makes the container use the host's network stack.
