Docker containers that host applications need underlying storage to store and manage application data and metadata related to the containers. Storage can either come from disk arrays or Direct Attached Storage (DAS) devices. There are three ways to provision storage for Docker containers.
Manually provision storage to a Docker daemon which in turn assigns storage to Docker containers.
Directly provision Docker volumes to Docker containers without the need of provisioning storage from Docker daemons.
Automatically provision storage for Docker containers through the Vertias Volume driver.
