+Docker Cheat Sheet:
+
+Docker Containers
+	docker search  # search the images in docker hub
+	docker pull    # pull image from docker hub
+	docker images  # list the images in local
+	docker run (interactive / detached ) # run a container from an image
+	docker ps      # list the running containers 
+	docker ps -a   # list running + exited containers
+	docker inspect # inspect a container
+	docker stop|start|restart   # stop/start/restart a container 
+	docker rm / docker rm -f    # remove the containers from the server
+	docker exec    # get inside a running container 
+
+Docker Images 
+	docker images  # list images in local
+	docker commit  ( manual )  # create image from container changes 
+	docker build ( automated ) # create image using a dockerfile
+	docker history # view the layers of an image
+	docker inspect # inspect an image
+	docker rmi     # remove image from local
+
+image repository 
+	docker hub (public)  # docker image reporsitory 
+	docker registry container (private) # docker image repository open source 
+	DTR (priviate)  # docker image repository licensed tool from docker org 
+		docker login  # login to image repo from commad line
+		docker tag    # create alias name for an image in local
+		docker push   # push images to docker image repository
+
+Docker Volumes
+	docker volume ls   # list volumes in local
+	docker volume create # create a volume 
+	docker inspect volume # inspect the volume
+
+Docker COMPOSE:
+
+  case 1: deploy multiple containers from a single image
+             docker-compose -f docker-compose.yml up --scale web=4 -d  ; docker-compose down
+  case 2: deploy multiple containers from multiple images
+             docker-compose -f docker-compose.yml -p webapps up -d --scale web=2 --scale app=2
+
+
+Docker Networking:
+	docker network ls   # list the default & custom networks on a docker host
+		none|host|bridge|overlay|docker_gwbridge
+	docker network create -d <driver> <network name>  # create a custom network of bridge/overlay
+	docker run -d --net host --name cont1 alpine      # attach a continer to host network
+	docker run -d --net none --name cont2 alpine      # attach a container to none network
+	docker run -d --net ravinet --name cont3 alpine   # attache a container to custom bridge/overlay network
+
+Docker Swarm
+
+	docker swarm init   ## initialize the swarm mode (swarm manager)
+	docker swarm join   ## join a node to manager as worker / manager
+	docker swarm join-token worker/manager ## generate worker/manager token
+	docker swarm leave ## run on worker nodes to leave the node from swarm 
+
+	docker node ls      ## list the node part of swarm
+	docker node inspect ## inspect a node 
+	docker node rm <nodename> ## run on manager node to remove a node from swarm
+	docker node ps	    ## List tasks running on one or more nodes, defaults to current node
+	
+	docker service create  ## create service in docker swarm cluster
+	docker service ls      ## list the running services 
+	docker service ps <service name>  ## list the containers running inside a service
+	docker service rm      ## remove the service
