Configuration maps are objects that provide mechanisms to inject configuration data into containers.

The values in secrets are always encoded (not encrypted).

A persistent volume claim (PVC) resource represents a request from an application for storage, and specifies the minimal storage characteristics, such as the capacity and access mode.

Kubernetes supports two volume modes for persistent volumes: Filesystem and Block.

Storage classes are a way to describe types of storage for the cluster and to provision dynamic storage on demand.

A reclaim policy determines what happens to the data on a PVC after the PVC is deleted.

A storage class with block volume mode support can improve performance for applications that can use raw block devices.

A stateful set is the representation of a set of pods with consistent identities.

Stateful set pods are assigned individual persistent volumes.
