Look inside

You’re a DevOps engineer for BuildYourHome, an e-commerce company with a newly containerized e-commerce application. As part of an ongoing effort to ensure web page updates are delivered seamlessly, you’ll store web page-related configuration information with Kubernetes objects, including ConfigMaps and Secrets, then inject them into your microservice containers. When done, you’ll have gained familiarity with maintaining stateful applications with Persistent Volumes and Persistent Volume Claims, as well as a solid understanding of how ConfigMaps and Secrets are used in a production environment.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
