docker v code example

Example 1: docker run command on container

sudo docker exec -it <container name> <command>

Example 2: docker mount volume

docker run -v /host/directory:/container/directory -other -options image_name command_to_run

Example 3: 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.
