Docker Cheatsheet with Example and Definition

Docker has revolutionized the way applications are developed and deployed. This Docker cheatsheet is your comprehensive guide to mastering Docker, complete with clear definitions and practical examples. Whether you’re a novice or a seasoned pro, this guide will help you streamline your Docker workflow.

What is Docker?

Docker is an open-source platform for developing, shipping, and running applications in containers. Containers package an application and its dependencies into a single unit, ensuring consistency across various environments.

Basic Docker Commands

Get started with these fundamental Docker commands:

docker run

Run a container from an image.

docker run -d -p 80:8080 my-app

docker build

Build an image from a Dockerfile.

docker build -t my-image .

docker pull

Download an image from a registry.

docker pull my-image

docker push

Push an image to a registry.

docker push my-image

Managing Containers

Efficiently manage containers with these commands:

Listing Containers

List running containers.

docker ps

Stopping and Removing Containers

Stop and remove containers.

docker stop my-container 
docker rm my-container

Working with Images

Master image manipulation with these commands:

Listing Images

List downloaded images.

docker images

Removing Images

Remove unused images.

docker image prune

Inspecting Images

Inspect image details.

docker inspect my-image

Docker Compose

Simplify multi-container applications with Docker Compose:

Defining Services

Define services in a docker-compose.yml file.

version: '3' 
    image: nginx

Running Services

Start services.

docker-compose up

Stopping Services

Stop services.

docker-compose down

Network and Volume Management

Manage networks and volumes efficiently:

Creating a Docker Network

Create a custom network.

docker network create my-network

Creating a Docker Volume

Create a named volume.

docker volume create my-volume

Advanced Docker Usage

Explore advanced Docker topics:

Dockerfile Best Practices

Follow Dockerfile best practices for efficient image builds.

Docker Hub and Registries

Publish and share images on Docker Hub or private registries.

Docker Swarm

Explore container orchestration with Docker Swarm for scaling and management.


Docker is a game-changer in the world of software development and deployment. This cheatsheet serves as your go-to reference for Docker commands and concepts. Whether you’re creating images, managing containers, or orchestrating multi-container applications, Docker’s versatility empowers you to build and deploy with confidence.
