Data Sources
In Terraform, a data source is a way to retrieve information about an entity that is not managed by the current Terraform configuration. Data sources provide dynamic information that can be used elsewhere in the Terraform configuration. Data sources are used to get information about resources external to Terraform and use them to set up Terraform resources. For example, a volume Dell Storage system exposes. Data sources are accessed via a special kind of resource known as a data resource, declared using a data block.Each data resource is associated with a single entity, which determines the kind of object it reads and what query constraint arguments are available.
