Lab: The Containerized SDLC
目录
Build a real Node.js API, then apply containers at every stage of the software development lifecycle. You'll write a Compose file for local development, integration tests using Testcontainers, a CI/CD pipeline, and Kubernetes manifests — using the same container image throughout.

What you'll learn
By the end of this Labspace, you will have completed the following:
- Set up a containerized local development environment with Docker Compose and Compose Watch
- Write integration tests that spin up a real database using Testcontainers
- Build a CI/CD pipeline that tests, builds, and pushes a container image automatically
- Write Kubernetes manifests and deploy a live application to a k3s cluster
- Configure the pipeline to cause an automatic deployment on every push to
