In today’s tutorial, we explore the world of expandable persistent volumes on Google Cloud. Here’s a quick breakdown of what we cover: setting up a standard Kubernetes cluster; authenticating the kubectl client and checking storage classes; uncovering the “allow volume expansion” field and understanding its role in volume expansion; taking a detailed look at the different storage classes and their support for volume expansion; crafting a persistent volume claim and introducing a pod through a YAML file; and testing our persistent volume’s capabilities, from creating a test file to expanding the volume from 8GB to 16GB— all without losing any data!
