Look inside

Interpop, a popular music-streaming service, wants its millions of customers across the globe to be able to view the same data—their user profiles and music playlists, for example—every time they open the service’s app. As Interpop’s new Kubernetes administrator, it’s up to you to prevent loss of data by setting up Interpop’s Kubernetes clusters to persist indefinitely. Using YAML, you’ll configure and create a persistent volume that allows for data to persist beyond the life of a pod (because pods are natively ephemeral). You’ll also create a persistent volume claim, ensuring that the app has enough storage to run efficiently. Using various storage allocation methods, you’ll streamline the process of creating storage on-the-fly, helping to boost Interpop’s developers’ productivity. To prepare for production, you’ll configure and run a MySQL database* and attach persistent storage to it. When you’re finished, you’ll have the skills and knowledge to prevent the loss of vital data, and Interpop will sing your praises!

*The approximate cost to run EKS in AWS Cloud is $4.33 USD.

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