Installing Docker and Managing Docker Daemon for OpsMate (Windows)

Business Scenario

Manager:
Great work team! The CI/CD pipeline has been successfully implemented, and deployments are now automated. However, the next challenge is setting up a proper containerized environment for the applications.

Manager:
We need Docker installation and proper Docker daemon management to ensure containers run efficiently and securely. Let’s discuss this with the DevOps Engineer.

DevOps Engineer:
Yes, Docker will help us create lightweight and portable containers for our applications. First, we need to install Docker on all required servers and configure the Docker daemon properly for stable container management.

Manager:
What issues can occur if the Docker daemon is not maintained correctly?

DevOps Engineer:
If the Docker daemon is not monitored or configured properly, containers may stop unexpectedly, resource usage can increase, and security risks may occur. Proper daemon management ensures container reliability, logging, restart policies, and better performance.

DevOps Engineer to Team:
Team, here is the implementation plan:

  • Install Docker Engine on all application servers.
  • Enable and start the Docker service using systemctl.
  • Configure the Docker daemon settings in the daemon.json file.
  • Set restart policies for containers to improve availability.
  • Monitor Docker logs and container health regularly.
  • Clean unused images and containers to optimize storage.
  • Secure the Docker daemon using proper permissions and firewall rules.

We will also verify the installation by running test containers and checking Docker service status continuously.

Team:
Understood. We will begin Docker installation, configure the Docker daemon, and ensure all containers are running properly with regular monitoring.

2) Building Blocks of Website,

3) Tag Titans: Fundamental Web Construct.

Task 1: Setup Docker on Windows and Verify Installation

1

Verify System Requirements

Before installing Docker, ensure:

  • Windows 10/11 (64-bit)

  • Virtualization enabled in BIOS

  • WSL2 feature enabled

  • At least 4 GB RAM

2

 Enable WSL

Open PowerShell as Administrator and run

wsl --install

Restart the system after installation.

3

Verify WSL Installation

wsl --status

4

Download Docker Desktop

  • Open browser

Visit:https://www.docker.com/products/docker-desktop/

  • Download Docker Desktop for Windows

5

Install Docker Desktop

  • Run the installer

  • Keep default options selected

  • Enable:

    • Use WSL 2 instead of Hyper-V

  • Click Install

  • Restart system if prompted

6

Launch Docker Desktop

Open:Docker Desktop

Wait until Docker shows: Docker Desktop is running

7

Verify Docker Installation

Open PowerShell

docker --version

Pre-Lab Preparation

  • Explore different restaurants

  • View food items and menus

  • Add items to cart

  • Place orders online

Task 1: Understanding BRD

Before you start building anything, you need to clearly understand what the client actually wants.So, let’s begin by understanding the BRD (Business Requirement Document) shared by the client.

BRD Full Form is Business Requirement Details.BRD like a plan for building a house. This plan helps the builder understand what to build.In the same way,BRD tells developers what the client wants to build

Click to download BRD : BiteBox_BRD.pdf

Activity

After going through BRD list down the Core Features and  Web Pages in the tabulated Format as shown Below.

Formula

Profit = Revenue - Cost

Task 2: Create WireFrame

Now that you understand the requirements, don’t jump into coding yet. Before development, we always visualize the layout.

Now lets  create a simple wireframe for the homepage.

A wireframe is like a layout plan of a house. Before building, you decide where rooms, doors, and windows will be placed.Similarly, a wireframe helps you plan where elements like headers, images, and buttons will appear on a webpage—before adding design or colours.

Task 3: Code Editor Installation

Good work on completing the planning phase.

Now we will start development. Before that, make sure your system is ready with the required tools.

In this step we will install the VS code editor that will help to Write code efficiently,Organize files , Run and test your application

Go to the visual studio code official website

    public static void main(String[] args) {
        int x = 10;
        int y = 20;
        int sum = x + y;
        
        System.out.println("The sum is: " + sum);
    }
}

public class MathSample {
    public static void main(String[] args) {
        int x = 10;
        int y = 20;
        int sum = x + y;
        
        System.out.println("The sum is: " + sum);
    }
}
