Kubernetes is an open-source container-orchestration system for automating application deployment, scaling, and management. It groups containers that make up an application into logical units for easy management and discovery.
Kubernetes Volumes enables data to outlive the lifetime of a pod. By default, when a pod is deleted, the data in the pod is also deleted. However, there are cases when data needs to be persisted even after the pod is deleted, for example, when an application is being updated. In such cases, Kubernetes Volumes comes in handy.
Kubernetes Volumes offers the following features:
1. Volumes are clustered and replicated.
2. Volumes can be attached and detached from running pods.
3. Volumes can be used with any container runtime.
4. Volumes can be used with any Kubernetes object.
Kubernetes Volumes have the following advantages:
1. Data is persisted even after the pod is deleted.
2. Volumes can be used with any container runtime.
3. Volumes can be used with any Kubernetes object.
The pricing of Kubernetes Volumes depends on the storage provider. For example, Amazon EBS charges $0.10 per GB-month, while Google Cloud Storage charges $0.026 per GB-month.
