Persistent Volume Expansion on Google Kubernetes Engine
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.
Testing our persistent volume's capabilities, from creating a test file to expanding the volume from 8GB to 16GB— all without losing any data!
