Kubernetes is one of the most popular orchestration solutions for hosting containers in a production environment. The platform allows users to automate the deployment of numerous instances of an application while scaling up and down according to demand.

However, due to the volatile nature of Kubernetes pods, storage volumes needed to be resolved with an entirely new approach.

I will try to explain what Kubernetes persistent volumes are and why they are so significant.

What are Kubernetes Persistent Volumes?

Kubernetes persistent volumes are user-provisioned storage volumes assigned to a Kubernetes cluster. Persistent volumes’ life-cycle is independent from any pod using it. Thus, persistent volumes are perfect for use cases in which you need to retain data regardless of the unpredictable life process of Kubernetes pods.

Without persistent volumes, maintaining services as common as a database would be impossible. Whenever a pod gets replaced, the data gained during the life-cycle of that pod would be lost. However, thanks to persistent volumes, data is contained in a consistent state.
