How Does Persistent Storage Work With Containers?
PVs are defined as the resources that have a independent lifecycle that makes use of PV. These are known as physical volume present on host machines that are used to store persistent data. The storage resources are provided in clusters by the PersistentVolumes. These volumes can be provisioned statistically or dynamically and can even be customized for use by defining their properties such as size, performance and the access modes.
PersistentVolumeClaim (PVC) are defined as the requests for resources that acts like a claim checks to the resources. It is a request platform used for creating the PersistentVolume and for attaching the PVs to pods through PVC.
What is Persistent Storage?
Any data storage system that keeps data after its power is turned off is said to be using persistent storage. It’s also known as nonvolatile storage at times. Persistent storage in the context of containerization refers to storage volumes that are accessible after a container has stopped running. These volumes are typically connected to stateful applications like databases. Ephemeral storage volumes, which are linked to stateless apps that live and die with containers, can be contrasted with persistent storage volumes.
