Day 2: Setting Sail with Docker - Your First Steps in Installation and Setup

Introduction

Namaste, tech enthusiasts! 🚀 Today, we're setting out on a thrilling journey – installing and setting up Docker, much like setting sail on a grand sea adventure. Let's explore how Docker opens a world of opportunities in software development.

Section 1: Preparing for the Journey - System Requirements and Pre-installation Checklist

First things first, let's ensure your system is ready for Docker:

• Windows and MacOS Users: Get ready for Docker Desktop.
• Linux Users: You'll be working with Docker Engine.
• Checklist: Confirm your system meets the memory and storage requirements.

Section 2: Installing Docker - A Step-by-Step Guide

Time to install Docker on your machine:

• Windows and MacOS Users:
  • Head over to Docker Desktop and download the installer.
  • Follow the installation wizard – it's straightforward.
• Linux Users:
  • Open your terminal and run sudo apt-get update.
  • Then, install with sudo apt-get install docker-ce docker-ce-cli containerd.io.
  • More details can be found on the Docker website.

Section 3: Verifying the Installation

To ensure Docker is set up properly:

• Open your terminal or command prompt.
• Run docker --version to check the installed Docker version.
• Next, try docker run hello-world. This command downloads a test image and runs it in a container. If this works, Docker is ready!

Section 4: Your First Docker Container

Let's run your first Docker container:

• In your terminal, type docker run hello-world.
• This command pulls the 'Hello World' image from Docker Hub and runs it in a container.
• You should see a message confirming your Docker container ran successfully.
