Cheat Sheet with Docker Teams

Note trans. : A week ago, Aymen El Amri, who runs eralabs and created the Painless Docker training course, published his Docker Cheat Sheet - a cheat sheet for the main Docker teams. The Git-repository of this document on GitHub has already gained 1000+ stars and several third-party contributors, which confirmed its relevance and benefit.



The commands presented here are described minimally (with an emphasis on readability as is) and include Docker installation, work with registries and repositories, containers, images, network, Docker Swarm. Below is a translation of the cheat sheet in its condition on September 2, with additions from the comments below.

Getting information about containers

Working containers

 docker ps -a 

Container logs

 docker logs infinite 

Container Information

 docker inspect infinite 

 docker inspect --format '{{ .NetworkSettings.IPAddress }}' $(docker ps -q) 

Container events

 docker events infinite

Image Management

List of images

 docker images 

Creating images

 docker build - < Dockerfile 

 docker build - < context.tar.gz 

 docker build -t eon/infinite . 

 docker build -f myOtherDockerfile . 

 curl example.com/remote/Dockerfile | docker build -f - . 

Deleting an image

Loading repository to tar (from file or standard input)

 docker load < ubuntu.tar.gz 

 docker load --input ubuntu.tar 

Saving the image to a tarball

 docker save busybox > ubuntu.tar 

View image history

 docker history 

Creating an image from a container

Image Tagging

 docker tag nginx eon01/nginx 

Push (load into the registry) image

 docker push eon01/nginx 

Network

Networking

 docker network create -d overlay MyOverlayNetwork 

 docker network create -d bridge MyBridgeNetwork 

 docker network create -d overlay \ --subnet=192.168.0.0/16 \ --subnet=192.170.0.0/16 \ --gateway=192.168.0.100 \ --gateway=192.170.0.100 \ --ip-range=192.168.1.0/24 \ --aux-address="my-router=192.168.1.5" --aux-address="my-switch=192.168.1.6" \ --aux-address="my-printer=192.170.1.5" --aux-address="my-nas=192.170.1.6" \ MyOverlayNetwork 

Network removal

Connecting the container to the network when it starts

 docker run -it -d --network=MyOverlayNetwork nginx 

Disconnecting the container from the network

 docker network disconnect MyOverlayNetwork nginx 

Cleaning docker

Removing a working container

 docker rm nginx 

Deleting a container and its volume

 docker rm -v nginx 

Delete all containers with exited status

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

Delete all stopped containers

 docker container prune 

 docker rm `docker ps -a -q` 

Removing containers stopped more than a day ago

 docker container prune --filter "until=24h" 

Deleting an image

 docker rmi nginx 

Removing unused (dangling) images

 docker image prune 

 docker rmi $(docker images -f dangling=true -q) 

Delete unused (dangling) images even with tags

 docker image prune -a 

Delete all images

 docker rmi $(docker images -a -q) 

Delete all images without tags

 docker rmi -f $(docker images | grep "^<none>" | awk "{print $3}") 

Stop and delete all containers

 docker stop $(docker ps -a -q) && docker rm $(docker ps -a -q) 

Removing unused (dangling) volumes

 docker volume prune 

 docker volume rm $(docker volume ls -f dangling=true -q) 

Removing unused (dangling) volumes by filter

 docker volume prune --filter "label!=keep" 

Removing unused networks

 docker network prune 

Deleting all unused objects

 docker system prune 

Docker 17.06.1+ does not delete volumes by default. To retire and they too:

 docker system prune --volumes 

Docker swarm

Install Docker Swarm

 curl -ssl https://get.docker.com | bash 

Note trans. : Docker version 1.12.0+ doesn’t need anything extra Docker Swarm is built into the Docker Engine as a special mode (Swarm mode).
