ZonedAccuracy CI/CD DevOps Pipeline

Automated CI/CD pipeline demonstrating application testing, containerization, continuous integration, and container publishing using GitHub Actions and Docker.

Overview

This project is part of the ZonedAccuracy Cloud Portfolio and demonstrates a production-style DevOps workflow for automatically testing, building, and publishing containerized applications.

Continuous Integration

Every push or pull request to main automatically:

• Checks out the repository
• Configures Node.js
• Executes automated tests
• Verifies application behavior
• Builds the Docker container
• Prevents CD execution when CI fails

Continuous Deployment

After a successful CI workflow, the CD pipeline automatically:

• Checks out the validated source code
• Configures Docker Buildx
• Authenticates to GitHub Container Registry
• Builds the production container
• Generates container metadata
• Publishes the image to GitHub Container Registry
• Creates latest and commit SHA image tags

Application

The containerized Node.js service exposes:

GET /
GET /health

Health response:

{
  "status": "healthy",
  "service": "zonedaccuracy-cicd"
}

Automated Testing

The test suite verifies:

• Root endpoint availability
• Health endpoint functionality
• HTTP 404 handling

Run locally:

npm test

Docker

Build:

docker build -t zonedaccuracy-cicd:1.0.0 .

Run:

docker run -d \
  --name zonedaccuracy-cicd \
  -p 3000:3000 \
  zonedaccuracy-cicd:1.0.0

Test:

curl http://localhost:3000/health

CI/CD Workflows

CI Workflow

ci.yml

Responsible for automated testing and Docker build validation.

CD Workflow

cd.yml

Runs only after successful CI and publishes the validated container image.
