In addition to the PV. PVS and StorageClass concepts, you may expand your knowledge by reading further on some of the important topics in Kubernetes. It is not a mandatory but good to have knowledge as a Kubernetes practitioner.
Ephemeral Volumes for Temporary Storage in Kubernetes
Ephemeral volumes offer a convenient way to provide temporary storage for pods in Kubernetes. They're perfect for applications that need scratch space for caching or require read-only data like configuration files or secrets. Unlike persistent volumes, ephemeral volumes are automatically deleted when the pod terminates, simplifying deployment and management.
Benefits:
- Temporary storage for pods
- Automatic deletion with pod termination
- Simplified deployment and management
Types:
- emptyDir: Creates an empty directory on the node's local storage
- ConfigMap, downwardAPI, secret: Injects data from Kubernetes objects into the pod
- CSI ephemeral volumes: Provided by external CSI drivers...
