SNU-DevOps

DevOps coursework (SNU Chennai, B.Tech CSE-IoT) — a progression of Git/version-control fundamentals through to CI/CD pipelines, containerization, and deployment strategies, plus the standalone lab-exercise repos from the same course merged in as subfolders.

Lab exercises (Lab/)

Exercise	Topic
Ex01_GithubBasic	Git & GitHub fundamentals
Ex02_GitLab	Git on GitLab
Ex03_Bitbucket	Git on Bitbucket
Ex04_GitAdvanced	Advanced Git commands
Ex05_Maven	Introduction to Maven
Ex06_JavaMaven	Java build automation with Maven
Ex07_JavaMavenManual	Manual Java/Maven project setup
Ex08_Jenkins	CI/CD for a web app using Jenkins, Git, and a local HTTP server (my-web-app/)
Ex09_Docker	Jenkins + Docker: containerizing an Apache server (docker-apache-server/)
Ex10_JenkinsDocker	CI/CD for a web app using Jenkins, Git, and Docker containers
Ex11_JenkinsDockerNode	CI/CD pipeline for a Node.js application using Jenkins and Docker
Ex12_BlueGreenDeployement	Blue-green deployment strategy for a Node.js application
CIA/CIA.md	Continuous assessment: Git fundamentals reference

QnA/	Written exercise answers (Maven build lifecycle customization, etc.)

Each ExNN folder has its own ExN.md writeup with the exercise steps; Ex08-Ex12 also include the actual project code, Ex01-Ex07 are primarily Git/Maven workflow exercises documented in their .md/.docx files.

Merged standalone-repo projects

These were originally separate repositories from the same course, merged here as top-level folders (full original commit history preserved via git subtree):

• DevOpsFinal — course final project (Dockerfile, Jenkinsfile, docker-compose, health checks)
• ModelLabDevOps — Maven/Jenkins model lab
• aws-cicd-pipeline-app — Node.js app with AWS CodeBuild / Azure Pipelines CI/CD config
• blue-green-deployment-app — Node.js blue-green deployment exercise
• nodejs-ci-cd-app — Node.js CI/CD pipeline exercise
• ci-cd-webapp — static webapp CI/CD exercise
• JenkinLabExercise — Jenkins pipeline exercise

Running

Most Lab/ExNN and merged-project folders are self-contained Node.js apps or static sites:

cd <folder>
npm install   # if package.json is present
node server.js   # or open index.html directly

Docker-based exercises (Ex09, Ex10-Ex12, and most merged projects) include a Dockerfile/compose file:

docker compose up --build
