Docker Cheat Sheet : Complete Guide (2024)

Last Updated : 23 Jul, 2025

Docker is a very popular tool introduced to make it easier for developers to create, deploy, and run applications using containers. A container is a utility provided by Docker to package and run an application in a loosely isolated environment. Containers are lightweight and contain everything needed to run an application, such as libraries and other dependencies packed by the developer during the application's packaging process. This assures developers that their application can be run on any other machine. Here, we're going to provide you with an ultimate Docker Cheat Sheet that will help you to learn Docker Commands easily.

This Docker command cheatsheet is a summary of commonly used Docker commands and their options, as well as other useful information related to Docker. It covers all the important commands required for Docker operations, including Docker installation, building, running, shipping, and cleaning up, as well as interaction with containers. This cheat sheet will be a handy reference for you to perform various tasks with Docker, such as installing, building, running, shipping, and cleaning up containers. This Docker cheat sheet is useful for both - DevOps freshers who're learning Docker and experienced Docker users who need to recall a specific command or option but may not remember all the details.

What is Docker?

Docker allows you to collect and run an application in a container, which is a loosely isolated environment. Because of the isolation and security, you can run multiple containers on a single host at the same time. Containers are lightweight and include everything required to run the application, eliminating the need to rely on what is already installed on the host. You may easily share containers while working, and you can ensure that everyone with whom you share gets the same container that functions in the same way.

Pre-requisite: Docker, DockerHub
The below Docker cheat sheet contains commands to manage the docker containers, images, network, volumes, building running, and deploying containers and also covered commands related to Docker Compose.

Docker Commands Cheat Sheet

The Docker cheat sheet will help you as a reference guide from where you can quickly read of mostly used common commands of Docker. The cheat sheet will help as a handy guide for developers and other system administrations who are working with Docker. Let's get started:

Installation Commands

Name	Command

Name	Command
Log in to a Registry	docker login
Logout from a Registry	docker logout
