Description

Kubernetes provides both ephemeral volumes that store their data only for the lifetime of the Pod, and persistent volumes that persist their data beyond the lifetime of the Pod they are mounted to. This lab explores ephemeral volumes. There are a variety of use cases for ephemeral volumes including:

  • Sharing data between containers in a Pod (multi-container Pods)
  • Providing read-only input configuration data to a Pod
  • Temporary data caches

You will understand how Kubernetes provides ephemeral storage and understand how to utilize ephemeral storage in this lab.

This lab is valuable to anyone working with Kubernetes, but the content has been prepared considering topics described in the Certified Kubernetes Application Developer (CKAD) Exam Curriculum. Completion of the lab will help you get hands-on experience, which is essential for passing the CKAD exam.

Learning Objectives

  • Utilize ephemeral volume types in Kubernetes applications
  • Specify ephemeral storage requirements and limits in Pod specs

Intended Audience

  • Kubernetes admins and operators
  • Application developers and DevOps engineers deploying applications in containers and using or considering Kubernetes
  • This lab is recommended for Certified Kubernetes Application Developer (CKAD) examinees

Prerequisites

  • Knowledge of Kubernetes Pod Design (Pods, Deployments, Services)
  • Experience with kubectl

You can complete the Kubernetes Pod Design for Application Developers lab series to satisfy the prerequisites.
