Module Overview

What You’ll Learn

• Explain what continuous integration and continuous deployment each actually automate
• Build a GitHub Actions workflow that runs a test suite on every push
• Extend that workflow to build and publish a Docker image automatically

💡 Why this matters: Module 7 and 8 of Authentication, Security & Testing for Node.js built a real, passing test suite, run by hand, whenever someone remembers to. CI/CD is what runs it automatically, on every single change, and stops a broken change from ever reaching production.

What’s Covered

• Continuous integration, running tests automatically on every push or pull request.
• GitHub Actions, workflows, jobs, steps, and triggers.
• Continuous deployment, automatically building and publishing a Docker image once tests pass.
• Pipeline secrets, providing a workflow with credentials safely, without ever committing them.

Hands-On

By the end of this module, you’ll have a GitHub Actions workflow that runs a real test suite and builds a Docker image automatically, on every push.

Next module: deploying that image to a real, live cloud platform.
