Using Static/Existing Disks for Persistent Volumes in GKE
Welcome to our comprehensive guide on utilizing static persistent volumes in Kubernetes, specifically within a Google Kubernetes Engine (GKE) environment. In this tutorial, we set up and leverage static persistent volumes as opposed to the dynamically-provisioned volumes commonly used in GKE. This method allows for the preloading of data on disks that can be utilized across multiple pods, as well as other non-standard storage/volume use cases.
Key Highlights:
Understanding the concept of static persistent volumes in Kubernetes.
Step-by-step guide on setting up a Kubernetes cluster in Google Kubernetes Engine.
How to create a persistent volume backed by an existing Google Compute Engine disk, including YAML configuration details.
Insights on using disks in a read-only format to empower multiple workloads, with the option for read-write if used by a single pod.
Live demonstration of deploying Nginx containers across multiple pods to utilize the static persistent volume claim.
Overview of storage class implications.
