What is a DevOps Capstone Project?

A DevOps Capstone Project is a final practical project that demonstrates your understanding of DevOps tools, practices, and workflows. It brings together what you’ve learned about development, operations, automation, CI/CD, monitoring, and cloud services.

The goal is to show how DevOps improves software delivery, reliability, and collaboration between development and operations teams.

Key Concepts in a DevOps Capstone Project:

  1. Continuous Integration (CI) – Automatically building and testing code.

  2. Continuous Deployment (CD) – Automatically deploying applications to staging or production.

  3. Infrastructure as Code (IaC) – Managing servers and resources with tools like Terraform or Ansible.

  4. Monitoring & Logging – Using tools like Nagios, Prometheus, Grafana, or ELK stack.

  5. Containerization – Using Docker to package and run applications.

  6. Orchestration – Managing containers with Kubernetes.

  7. Version Control – Using Git and GitHub/GitLab.

  8. Cloud Platforms – Deploying on AWS, Azure, or GCP.

CI/CD Pipeline Using Jenkins – In Short

A CI/CD pipeline automates the process of building, testing, and deploying code. Jenkins is a popular tool to set up and manage this pipeline.

CI/CD Pipeline Steps with Jenkins:

  1. Code Commit
    Developer pushes code to a Git repository (like GitHub).

  2. Build
    Jenkins detects the change (via webhook or polling) and pulls the latest code.

  3. Test
    Jenkins runs automated tests (unit/integration) to check code quality.

  4. Package
    If tests pass, Jenkins builds a deployable file (like .jar, .war, or Docker image).

  5. Deploy
    Jenkins deploys the code to a server or container (e.g., AWS, Tomcat, Docker, Kubernetes).

  6. Notification
    Jenkins sends success/failure status to email, Slack, etc.

Tools Used with Jenkins:

  • Git – For source control

  • Maven/Gradle/NPM – For build automation

  • Docker – For containerization (optional)

  • SonarQube – For code analysis (optional)

  • AWS/FTP/Tomcat – For deployment

Benefits:

  • Fast and automatic deployment

  • Fewer manual errors

  • Continuous feedback

  • Reliable delivery

What Git is needed for:
Git is a version control system that lets you track code changes, work in teams without losing work, roll back mistakes, and integrate smoothly with CI/CD tools like Jenkins.

Core Requirements to Use Git

  1. Install Git on your system (Windows, macOS, Linux).

  2. Configure identity: git config --global user.name "Your Name" and git config --global user.email "you@example.com".

  3. Have a repository: local repo (git init) or clone remote (GitHub/GitLab/Bitbucket).

  4. Network access (if using remote): HTTPS or SSH keys set up for push/pull.

  5. Basic commands knowledge: add, commit, status, push, pull, branch, merge.

  6. Ignore unwanted files: use a .gitignore file.

  7. Good commit messages so history is clear.

Why Git Is Required in DevOps/CI-CD

  • Tracks every change (history + rollback).

  • Enables branching & merging for parallel development.

  • Triggers automated builds in Jenkins when code is pushed.

  • Supports code review via pull/merge requests.

  • Central source of truth for teams.

Maven – Requirements (In Short)

What is Maven?
Maven is a build automation and dependency management tool for Java projects. It compiles code, manages libraries (dependencies), runs tests, and packages the project (e.g., into a .jar or .war file).

Requirements to Use Maven:

  1. Java Installed

    • Install JDK (Java Development Kit)

    • Set JAVA_HOME environment variable

  2. Maven Installed

    • Download Apache Maven

    • Set MAVEN_HOME and update system PATH

  3. Project Structure

    • Use Maven’s standard folder structure (src/main/java, src/test/java, etc.)

  4. pom.xml File

    • Main configuration file for Maven

    • Contains project details, dependencies, build plugins, etc.

  5. Internet Connection (for downloading dependencies from central repository)

 Common Maven Commands:

Command Use
mvn clean Cleans previous build files
mvn compile Compiles the source code
mvn test Runs tests
mvn package Packages project (creates .jar/.war)
mvn install Installs package in local Maven repo
mvn deploy Deploys project to remote repo (if configured)

 Why Maven is Used in DevOps/CI-CD?

  • Automates build and test steps

  • Manages all required libraries and dependencies

  • Works well with Jenkins and Git

  • Ensures consistent builds across environments

Docker – Requirements

What is Docker?
Docker is a platform that lets you package applications into containers — lightweight, portable environments that run the same everywhere.

Requirements to Use Docker:

  1. Operating System

    • Supports Windows, Linux, and macOS

    • For Windows: Requires Windows 10/11 Pro, Enterprise, or WSL2 (for Home edition)

  2. Docker Engine Installed

    • Install Docker Desktop or Docker Engine

    • It provides the core components like Docker CLI, Docker Daemon, etc.

  3. Virtualization Enabled

    • Required in BIOS settings for Docker to run containers

  4. Sufficient RAM

    • At least 4 GB RAM recommended (more for large containers)

  5. Command Line Knowledge

    • Basic terminal/command prompt usage

    • Familiarity with commands like docker build, docker run, etc.

Optional (but useful):

  • Docker Hub Account – To push/pull container images

  • Docker Compose – For multi-container applications

  • Git – To clone code and integrate with CI/CD tools

Why Use Docker?

  • Runs same app on any machine

  • Easy deployment

  • Saves system resources vs VMs

  • Used in DevOps pipelines, CI/CD, microservices, etc.

Testing Requirement (Dummy Job) – In Short

Since actual testing wasn’t implemented in the pipeline, a dummy testing stage is added to simulate testing as a placeholder.

Why Add a Dummy Testing Step?

  • To maintain CI/CD structure (build → test → deploy)

  • To reserve a place for future real test scripts

  • To show pipeline completeness in reports or presentations

How It’s Usually Done:

In Jenkins Pipeline (Jenkinsfile), a dummy test stage can look like:

stage('Test') {

steps {
echo 'Running dummy tests...'
sh 'echo All tests passed!'
}
}

Summary:

  • Dummy testing means no real code is tested.

  • It’s used just for structure, demo, or placeholder.

  • You can replace it later with real unit/integration tests.

Send an Email to Developer – In Short

In a CI/CD pipeline or DevOps process, sending an email to the developer is done to notify them about:

  • Build success or failure

  • Test results

  • Deployment status

  • Errors or warnings

When Is Email Sent?

  • After build/test/deployment stages

  • On failure or success events

How to Send Email in Jenkins (Example):

post {
failure {
mail to: 'developer@example.com',
subject: 'Build Failed',
body: 'The build has failed. Please check the Jenkins console for details.'
}
}

Or using Email Extension Plugin in Jenkins.

 Summary:

  • Keeps the developer informed

  • Helps with faster debugging

  • Can be configured to send to team, manager, or DevOps

Prepare Production Server (Linux – Ubuntu or RedHat) – In Short

Preparing a production server means setting up a stable, secure, and ready-to-deploy environment for your application.

Whether it’s Ubuntu or RedHat, the steps are mostly similar.

Basic Steps to Prepare Production Server:

  1. Choose OS

    • Use Ubuntu Server or RedHat Enterprise Linux (RHEL)

    • Keep it minimal (no GUI) for performance

  2. Update System

    • Ubuntu: sudo apt update && sudo apt upgrade

    • RHEL: sudo yum update

  3. Create User & SSH Access

    • Add a non-root user

    • Set up SSH key-based login for security

  4. Install Required Packages

    • Git, Docker, Java, Nginx, Node.js (based on your app)

  5. Configure Firewall

    • Allow only necessary ports (e.g. 22, 80, 443)

  6. Install & Start Services

    • E.g., Nginx or Apache for web server

    • Docker or Java runtime for app deployment

  7. Secure the Server

    • Disable root SSH login

    • Use UFW (Ubuntu) or firewalld (RHEL)

    • Install fail2ban or configure SELinux (for RHEL)

  8. Test the Server

    • Confirm services are running

    • Check logs and resource usage

 Summary:

A production server must be clean, secure, updated, and only running what’s needed for your application to run smoothly.

Run Docker Container in Production – In Short

Running a Docker container in production means deploying your application using a Docker image on a live server (e.g. Ubuntu or RedHat).

 Basic Steps:

  1. Login to Production Server

    ssh user@server-ip

  2. Install Docker (if not already)

    sudo apt install docker.io # Ubuntu
    sudo yum install docker # RedHat

  3. Pull Your Docker Image

    docker pull your-image-name

  4. Run the Container

  5. docker run -d -p 80:80 --name myapp your-image-name

    • -d: run in background (detached mode)

    • -p 80:80: map container port to server port

    • --name: name the container

  6. Verify It’s Running

    docker ps


    curl http://localhost # or check in browser using server IP

 Example:

docker run -d -p 8080:8080 --name webapp myapp:latest

 Optional (for Production):

  • Use Docker Compose for multi-container setup

  • Enable logging and monitoring

  • Set up reverse proxy (e.g., Nginx)

  • Use volumes for persistent data.
