  Build an image from the Dockerfile in the current directory and tag the image
    docker build -t <IMAGE_NAME>:1.0 .
  
  List all images that are locally stored with the Docker Engine
    docker image ls
    
  Delete an image from the local image store
    docker image rm alpine:3.4
    
##Share
  Pull an image from a registry 
    docker pull myimage:1.0

  Retag a local image with a new image name and tag
    docker tag myimage:1.0 myrepo/myimage:2.0

  Push an image to a registry
    docker push myrepo/myimage:2.0
    
##Run
  Run a container from the Alpine version 3.9 image, name the running container “web” and expose port 5000 externally, mapped to port 80 inside the container.
    docker container run --name <CONTAINER_NAME> -p 5000:80 alpine:3.9

  Stop a running container through SIGTERM
    docker container stop <CONTAINER_NAME>

  Stop a running container through SIGKILL
    docker container kill <CONTAINER_NAME>

  List the networks
    docker network ls

  List the running containers (add --all to include stopped containers)
    docker container ls

  Delete all running and stopped containers
    docker container rm -f $(docker ps -aq)

  Print the last 100 lines of a container’s logs
    docker container logs --tail 100 <CONTAINER_NAME>

##Cleanup

  List all exited containers
    docker ps -a -f status=exited

  Purging All Dangling Images, Containers, Volumes, and Networks
    docker system prune
    
  Purging All Unused and Dangling Images, Containers, Volumes, and Networks
    docker system prune -a
  
  List containers using more than one filter
    docker ps -a -f status=exited -f status=created

  Remove containers using more than one filter
    docker rm $(docker ps -a -f status=exited -f status=created -q)
    
  List one or more specific volumes - Docker 1.9 and later
    docker volume ls

  Remove one or more specific volumes - Docker 1.9 and later
    docker volume rm volume_name volume_name

  List dangling volumes - Docker 1.9 and later
    docker volume ls -f dangling=true
  
  Remove dangling volumes - Docker 1.9 and later
    docker volume prune
    
  Remove a container and it's volume
    docker rm -v <CONTAINER_NAME>

    docker-compose up -d
  Stop Docker Container
    docker-compose down
    
##Docker Logon To Terminal
  Login as default user
    docker exec -it <CONTAINER_NAME> /bin/bash
