DevOps Engineer – Complete Syllabus

📘 Program Overview

Module 1: DevOps Fundamentals

Objectives

Understand DevOps culture, principles, and lifecycle integration.

Topics

• Introduction to DevOps
• DevOps lifecycle
• CALMS model
• SDLC vs DevOps
• Agile & Scrum basics
• CI/CD concepts
• DevOps roles and responsibilities

CI/CD Lifecycle Flow

Plan → Code → Build → Test → Release → Deploy → Operate → Monitor

Module 2: Linux & System Administration

Objectives

Build strong system-level foundation.

Core Linux Commands

Example Bash Deployment Script

#!/bin/bash

echo "Starting deployment..."
git pull origin main
npm install
npm run build
pm2 restart app
echo "Deployment completed successfully!"

Module 3: Networking Fundamentals

Objectives

Understand networking concepts required for deployment.

Key Concepts

Example: Nginx Reverse Proxy Configuration

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Module 4: Version Control Systems

Objectives

Manage source code effectively.

Common Git Commands

git init
git add .
git commit -m "Initial commit"
git branch -M main
git push origin main

Branching Strategies

Module 5: Continuous Integration & Continuous Deployment (CI/CD)

Objectives

Automate build, test, and deployment processes.

Example GitHub Actions Workflow

name: CI Pipeline

on:
  push:
    branches: [ "main" ]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3
      - run: npm install
      - run: npm test
      - run: npm run build

Deployment Strategies

Module 6: Containerization

Objectives

Package applications for portability and scalability.

Dockerfile Example

FROM node:18

WORKDIR /app

COPY package*.json ./
RUN npm install

COPY . .

EXPOSE 3000
CMD ["npm", "start"]

Docker Commands

docker build -t myapp .
docker run -d -p 3000:3000 myapp
docker ps
docker logs container_id

Module 7: Container Orchestration (Kubernetes)

Objectives

Manage containers at scale.

Kubernetes Deployment YAML

apiVersion: apps/v1
kind: Deployment
metadata:
  name: app-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: app
  template:
    metadata:
      labels:
        app: app
    spec:
      containers:
      - name: app
        image: myapp:latest
        ports:
        - containerPort: 3000

Kubernetes Core Components

Module 8: Cloud Computing

Objectives

Deploy and manage infrastructure in cloud environments.

Cloud Service Models

Module 9: Infrastructure as Code (IaC)

Objectives

Automate infrastructure provisioning.

Terraform Example

provider "aws" {
  region = "ap-south-1"
}

resource "aws_instance" "example" {
  ami           = "ami-1234567890"
  instance_type = "t2.micro"
}

IaC Advantages

Module 10: Monitoring & Observability

Objectives

Monitor system health and performance.

Monitoring Stack

Prometheus Query Example

rate(http_requests_total[5m])

Module 11: Security & DevSecOps

Key Practices

• Enforce HTTPS
• Apply least privilege IAM
• Secure secrets management
• Container vulnerability scanning
• Logging & auditing enabled

Module 12: Advanced Concepts

• Microservices architecture
• API gateways
• Service mesh
• High availability
• Disaster recovery
• Performance optimization
• Site Reliability Engineering (SRE)
