Docker Setup Guide

This guide will walk you through the process of setting up Docker on your system. Docker is a platform for developing, shipping, and running applications. It allows you to separate your applications from your infrastructure so you can deliver software quickly.

Prerequisites

Before you begin, make sure you have the following prerequisites:

• Docker Engine
• Docker Compose (optional, for managing multi-container Docker applications)

Installation

On Linux

1. Update your package index:

   sudo apt-get update
   

2. Install the required packages:

   sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
   

3. Add the GPG key for the official Docker repository:

   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
   

4. Add the Docker repository to your system:

   sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
   

5. Update your package index:

   sudo apt-get update
   

6. Install Docker Engine:

   sudo apt-get install docker-ce
   

7. Start the Docker service:

   sudo systemctl start docker
   

8. Verify the installation:

   sudo docker run hello-world
   

On macOS

1. Download Docker Desktop from the Docker website.
2. Open the downloaded DMG file and drag Docker Desktop to your Applications folder.
3. Open Docker Desktop and follow the setup instructions.
4. Verify the installation by running:

   docker run hello-world
   

On Windows

1. Download Docker Desktop from the Docker website.
2. Open the downloaded file and follow the setup instructions.
3. Verify the installation by running:

   docker run hello-world
   

Next Steps

Now that you have Docker installed, you can start using Docker to build and run your applications.

Note: If you encounter any issues during the installation process, please refer to the Docker documentation for more detailed troubleshooting steps.
