Docker is an open-source platform that simplifies the method of constructing, delivery, and working purposes utilizing containers. Containers permit builders to bundle purposes and their dependencies, making them moveable and constant throughout completely different environments. This Docker cheat sheet gives a fast reference information to important instructions and ideas for successfully working with Docker.

What’s Docker?

Docker cheat sheet

Docker is a containerization platform enabling builders to create, deploy, and handle purposes inside remoted containers. These containers bundle the applying code, runtime, libraries, and dependencies, making certain consistency and effectivity throughout numerous programs.

Docker Structure

Docker follows a client-server structure:

  • Docker Consumer: The command-line device that permits customers to work together with the Docker daemon.
  • Docker Daemon: The background service answerable for constructing, working, and managing Docker containers.
  • Docker Photos: Learn-only templates used to create containers.
  • Docker Containers: Working cases of Docker photos.
  • Docker Registry: A repository for storing and distributing Docker photos.

Set up of Docker

Installation of Docker | Docker cheat sheet

To put in Docker in your system, observe the suitable directions on your working system. Under are the steps for Home windows and MacOS.

Home windows

Verify system necessities

Home windows 10 64-bit: Professional, Enterprise, or Training editions

{Hardware} Virtualization enabled in BIOS/UEFI (Intel VT-x/AMD-V)

Obtain Docker Desktop

Go to Docker’s official web site and obtain the Docker Desktop installer for Home windows.

Set up Docker Desktop

Run the installer you downloaded and observe the set up wizard. It’s going to information you thru the method.

Begin Docker

As soon as put in, Docker Desktop ought to begin mechanically. You’ll see the Docker icon within the system tray when it’s working.


Verify system necessities

macOS Sierra 10.12 or newer

macOS have to be a 2010 or newer mannequin, with Intel’s {hardware} help for Reminiscence Administration Unit (MMU) virtualization.

Obtain Docker Desktop for Mac

Go to Docker’s official web site and obtain the Docker Desktop installer for macOS.

Set up Docker Desktop

Open the downloaded .dmg file, and drag the Docker icon into the Purposes folder.

Begin Docker

Open Docker from the Purposes folder. It’s going to seem within the menu bar, indicating that it’s working.

Docker Registry and Repository

Docker Registry is a service that shops and manages Docker photos. It acts as a central repository the place customers can retailer, share, and pull Docker photos. Docker Hub is a public Docker Registry, whereas non-public registries will be arrange for safe inside picture storage. 

A Docker Repository is a set of associated photos with the identical identify, differentiated by tags representing completely different variations or configurations. Customers can push photos to a repository in a registry, and others can pull these photos to run containers. Registries and repositories are essential in simplifying picture distribution and facilitating collaborative improvement within the Docker ecosystem.

Under are the docker cheat sheet instructions for numerous functions-

Working Containers

To run a container from a picture, use the next command: docker run [options] IMAGE [command]

For instance, to run an Nginx internet server: docker run -d -p 80:80 nginx

Beginning or Stopping the Container

  1. To begin a stopped container, use: docker begin CONTAINER_ID
  2. To cease a working container, use: docker cease CONTAINER_ID

Acquiring Container Info

  1. To record all working containers, use: docker ps
  2. To view all containers (together with stopped ones), use: docker ps -a

Managing Photos

  1. To drag a picture from a registry, use: docker pull IMAGE_NAME[:TAG]
  2. To construct a picture from a Dockerfile, navigate to the Dockerfile listing and use: docker construct -t IMAGE_NAME[:TAG].


  1. To create a user-defined bridge community, use: docker community create NETWORK_NAME
  2. To attach a container to a community, use: docker community join NETWORK_NAME CONTAINER_NAME

Cleansing Docker

  1. To take away a stopped container, use: docker rm CONTAINER_ID
  2. To take away a picture, use: docker rmi IMAGE_NAME
  3. To scrub up unused assets (containers, networks, photos, and volumes), use: docker system prune


Docker Compose is a device for outlining and managing multi-container Docker purposes. It configures the applying’s providers, networks, and volumes utilizing a YAML file. With Docker Compose, you may simply spin up complicated environments and purposes. Listed here are the instructions for it Docker Compose cheat sheet-

  1. To create and begin all containers outlined within the docker-compose.yml file use: docker-compose up
  2. To create and begin containers in indifferent mode use: docker-compose up -d
  3. To cease and take away all containers, networks, and volumes created by docker-compose up use: docker-compose down
  4. To record all working containers outlined within the docker-compose.yml file use: docker-compose ps
  5. To view the logs of a selected service use: docker-compose logs [service_name]
  6. To construct or rebuild the pictures outlined within the docker-compose.yml file use: docker-compose construct
  7. To execute a command inside a selected service container use: docker-compose exec [service_name] [command]


Providers in Docker Swarm mode outline the duties on a cluster. They permit you to scale the applying throughout a number of nodes and guarantee excessive availability. Listed here are the instructions for it: 

  1. To initialize a Docker Swarm on the present node, use: docker swarm init
  2. To hitch a Docker Swarm as a employee node use the next: docker swarm be a part of
  3. To record nodes within the Docker Swarm, use: docker node ls
  4. To create a brand new service use the next: docker service create
  5. To record all providers working within the Swarm, use: docker service ls
  6. To record duties (containers) of a service use: docker service ps [service_name]
  7. To scale a service to N replicas, use: docker service scale [service_name]=N
  8. To replace a service (e.g., change replicas, picture model), use: docker service replace
  9. To take away a service from the Swarm, use: docker service rm [service_name]
  10. To set a node to “drain” mode, which means it is not going to obtain new duties use: docker node replace –availability drain [node_name]

Interplay with a Container

To execute instructions inside a working container, use: docker exec [options] CONTAINER_ID COMMAND [ARG…]

For instance, to entry the shell of a working container: docker exec -it CONTAINER_ID sh

Vital Phrases

  • Picture: A light-weight, standalone, and executable software program bundle that features the whole lot wanted to run a bit of software program, together with the code, runtime, libraries, and dependencies.
  • Container: An occasion of a Docker picture that may be run, began, stopped, and deleted.
  • Dockerfile: A textual content file that accommodates directions for constructing a Docker picture.
  • Registry: A storage and content material supply system for named Docker photos.
  • Repository: A group of Docker photos with the identical identify, distinguished by tags.
  • Docker Compose: A device for outlining and managing multi-container Docker purposes.
  • Docker Swarm: A local clustering and orchestration answer for Docker.


In conclusion, Docker is a necessary containerization platform that simplifies the method of constructing, delivery, and working purposes by encapsulating them and their dependencies in remoted containers. With this complete cheat sheet, customers can effectively harness the facility of Docker, streamline software deployment, and keep consistency throughout numerous environments.
