In this video, I demonstrate two types of Kuberenetes volumes for persisting data between microservice calls. The first type is an emptyDir. This works on a single Kubernetes Pod but has limited value because if the Pod is restarted, the persisted value is lost. The second demonstration uses a HostPath. This is better than the emptyDir but still has problems as the persisted data exists on the Kubernetes Node. A better way of doing it is with a persistent volume, which will be demonstrated in the next video in the microservices playlist.
