docker build -t image-name .

  • Run “image-name” mapping port 8080 to 80

docker run -p 8080:80 image-name

  • Run “image-name” mapping port 8080 to 80, but in detached mode

docker run -d -p 8080:80 image-name

  • See a list of all running containers

docker ps

  • Gracefully stop the specified container

docker stop <hash>

  • See a list of all containers, even the ones not running

docker ps -a

  • Force shutdown of the specified container

docker kill <hash>

  • Remove the specified container from this machine

docker rm <hash>

  • Remove all containers from this machine

docker rm $(docker ps -a -q)

  • Show all images on this machine

docker images -a

  • LEGACY: Remove the specified image from this machine

docker rmi <imagename>

  • LEGACY:Remove all images from this machine

docker rmi $(docker images -q)

  • LEGACY: Remove all images with dependencies

docker images -q | xargs docker rmi –f

  • Log in this CLI session using your Docker credentials

docker login

  • Tag for upload to registry

docker tag <image> username/repository:tag

  • Upload tagged image to registry

docker push username/repository:tag

  • Run image from a registry

docker run username/repository:tag

  • List Docker volume

docker volume ls

  • List Docker Network

docker network ls

  • Access an already running container and perform operations inside it

docker exec -it <containerId> bash

Docker Compose Docker

  • Build Docker Images using Docker Compose file

docker-compose build

  • Run Docker Containers

  • List Docker Nodes in Swarm Cluster

docker node ls

  • List all running applications on this Docker host

docker stack ls

  • Run the specified Compose file

docker stack deploy -c <composefile> <STACK_NAME>

  • List the services associated with an app

docker stack services <appname>

  • List the running containers associated with an app

docker stack ps <appname>

  • Tear down an application

docker stack rm <STACK_NAME>alias dstr='docker stack rm'

  • Docker Swarm Service list

docker service ls alias dsls='docker service ls'

  • List the tasks of one or more services

docker service ps <service_name> alias dsp='docker service ps'

  • Docker Swarm Service logs

alias dsl='docker service logs'

  • Remove specific docker swarm service

alias dsr='docker service rm'

  • Remove unused Containers, Images, Network, etc.

alias sprune='docker system prune'

  • Remove unused Volumes

alias vprune='docker volume prune'

  • Create Secret

docker secret create <SECRET_NAME> <SECRET_PATH>

  • Create Config

docker config create <CONFIG_NAME> <CONFIG_FILE_PATH>

To delete all containers including its volumes use,

docker rm -vf $(docker ps -a -q)

To delete all the images,

docker rmi -f $(docker images -a -q)

Remember, you should remove all the containers before removing all the images from which those containers were created.

In case you are working on Windows (Powershell),

$images = docker images -a -q
foreach ($image in $images) { docker image rm $image -f }

To delete all images

docker rmi $(docker images -a)

To delete containers which are in exited state

docker rm $(docker ps -a -f status=exited -q)

To delete containers which are in created state

docker rm $(docker ps -a -f status=created -q)

NOTE: Remove all the containers then remove the images

Docker run bash shell of image

docker run -it --entrypoint bash <image-name>

List all docker commands
