Stateful applications are applications with memory of the past. Kubernetes has achieved wide adoption for deploying stateless applications. Kubernetes also provides a rich set of features for running stateful applications. Adoption of Kubernetes for stateful applications is growing and so is the list of stateful workloads that are supported by Kubernetes. In this lab, you will deploy a stateful application in a Kubernetes cluster to understand how Kubernetes supports stateful applications.

Learning Objectives

Upon completion of this lab you will be able to:

  • Describe methods for deploying Kubernetes clusters in the cloud
  • Explain how Kubernetes can deploy stateful applications
  • Determine if it is a good idea to move a stateful application into Kubernetes
  • Use Kubernetes to automatically provision persistent cloud storage volumes
  • Expose Kubernetes applications via cloud load balancers
  • Monitor and manage Kubernetes clusters using the Kubernetes Dashboard


You should be familiar with:

  • Basic Kubernetes concepts such as pods, services, and deployments
  • AWS EBS volumes
  • Working on the command line in Linux
