Login

docker login docker.io
The authentication information is stored at:
cat /root/.docker/config.json

Image operation

• Show the list of images which are available locally
  docker images
docker images -a
docker images -q
docker images -qa
docker images --digest
docker images --digest --no-trunc
• Search the image in the repository
  docker search tomcat
docker search -s 30 tomcat
docker search -s 30 --no-trunc tomcat
• Tag the specified image
  docker tag 965ea09ff2eb docker.io/mmdghh/alpine:v3.10.3

docker push docker.io/mmdghh/alpine:v3.10.3

docker rmi 965ea09ff2eb

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

Container operation

• 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

Run tomcat on host machine through port mapping

• 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.

Modify an image

Create the modified image

docker commit -a="[AUTHOR NAME]" -m="[DESC]" [CONTAINER ID] [PACKAGE]/[IMAGE NAME][VERSION ID]
