Persistent Volume Example in Kubernetes - Stateful Application
Welcome back on Kubernetes tutorial series. In today's tutorial , we will talk about using persistent volumes in kubernetes and a quick demo of setting up persistent volume on your local machine. Persistent volumes are useful for stateful application development where you always keep record of last information processed or maintain database transactional status. We all know by default if your Pod re-starts then you loose current status of your application which may not be applicable in every scenario.
