2. Course Objectives

This topic introduces essential DevOps practices for developers, covering containerization with Docker, CI/CD automation pipelines, and continuous code quality with SonarQube. Trainees will learn how to containerize applications, automate build/test/deploy workflows, and integrate code quality gates into their development process.

[!NOTE] This topic equips trainees with practical DevOps skills needed to ship reliable, production-ready applications — from writing optimized Dockerfiles to setting up CI/CD pipelines and enforcing code quality standards.

Output Standards Table

Name	Code	Description
Docker	OS1	Understand containerization concepts and write production-ready Dockerfiles with security best practices.
CI/CD	OS2	Design and implement automated CI/CD pipelines using GitHub Actions and GitLab CI.
Code Quality	OS3	Configure SonarQube for continuous code quality analysis and integrate it into CI/CD workflows.
Deployment	OS4	Apply deployment strategies (Blue-Green, Canary, GitOps) for reliable production releases.

Detailed Learning Outcomes (LOs)

• Containerization with Docker

  • OS1 LO-1 — Explain the difference between containers and virtual machines and identify when to use each.
  • OS1 LO-2 — Use essential Docker commands for image and container management (build, run, stop, logs, exec).
  • OS1 LO-3 — Write optimized Dockerfiles with layer caching, dependency caching, and appropriate base images.
  • OS1 LO-4 — Implement multi-stage builds to reduce final image size and separate build/runtime concerns.
  • OS1 LO-5 — Apply Docker security best practices: non-root users, image scanning, secrets management, and capability dropping.

• CI/CD Automation Pipelines

  • OS2 LO-6 — Explain CI/CD fundamentals: Continuous Integration, Continuous Delivery, and Continuous Deployment.
  • OS2 LO-7 — Create GitHub Actions workflows with triggers, jobs, steps, matrix builds, caching, and secrets.
  • OS2 LO-8 — Create GitLab CI pipelines with stages, services, artifacts, and environment-specific deployments.
  • OS2 LO-9 — Design automated test pipelines following the test pyramid (unit, integration, E2E).

• Deployment Strategies

  • OS4 LO-10 — Implement Blue-Green deployment with zero-downtime switching and health checks.
  • OS4 LO-11 — Implement Canary deployment with gradual rollout and metric-based promotion.
  • OS4 LO-12 — Set up GitOps workflows using Git as the single source of truth for infrastructure state.

• Continuous Code Quality with SonarQube

  • OS3 LO-13 — Describe SonarQube architecture and its role as an AI-native code verification platform.
  • OS3 LO-14 — Configure SonarQube quality gates and understand core metrics (Bugs, Vulnerabilities, Code Smells, Coverage).
  • OS3 LO-15 — Integrate SonarQube scanning into GitHub Actions and GitLab CI pipelines.
  • OS3 LO-16 — Apply the "Clean as You Code" methodology to enforce quality on new code without blocking legacy issues.
