If the image is referenced in multiple repostories, deletion must be forced
docker rmi -f 965ea09ff2eb
delete all
docker rmi -f $(docker images -qa)

Create and run a container
docker run -it [IMAGE ID]

-i, –interactive Keep STDIN open even if not attached
-t, –tty Allocate a pseudo-TTY
Create and run a container, with another name specified
docker run -it --name ABC [IMAGE]
Create and run a container in background
docker run -d [IMAGE ID]
Show all the containers/processes running in docker
docker ps
Show the most recently running container
docker ps -l
Show the recent 6 running containers
docker ps -l n 6
Exit the container and stop it
exit
Exit the container without terminating it
ctrl + P + Q
Start a container
docker start [CONTAINER NAME/ID]
Stop a container
docker stop [CONTAINER NAME/ID]
docker kill [CONTAINER NAME/ID]
Stop multiple containers
docker stop $(docker ps -p)
Remove a container
docker rm [CONTAINER ID]
Remove multiple containers
docker rm -f $(docker ps -q)
docker rm -f $(docker ps -a -q)
docker ps -a -q | xargs docker rm
Logs of a container
docker logs -f -t --tail [CONTAINER ID]
Show detailed information of a container
docker inspect [CONTAINER ID]
Run command on the host and outside of the container
docker exec -t [CONTAINER NAME/ID] ls -l /tmp
Reenter the container after ctrl + P + Q
docker attach [CONTAINER ID]
docker exec -t [CONTAINER NAME/ID] /bin/bash
Copy a file of a container to the host
docker cp [CONTAINER ID]:/tmp/yum.long /root

docker run -it -p [HOST PORT]:[IMAGE PORT] [IMAGE NAME]
e.g.,
docker run -it -p 8888:8080 tomcat:8.0.41

-p indicates that the port number afterwards is user-specified.
8888 is the user-specified port number of host machine.

docker run -it -P [IMAGE NAME]
e.g.,
docker run -it -P tomcat:8.0.41
-P indicates that the port number afterwards is specified by host OS.
