# retrieve information by name
storage-get -s data/0
Details¶
When no <key> is supplied, all keys values are printed.
Further details: storage-get obtains information about storage being attached to, or detaching from, the unit.
If the executing hook is a storage hook, information about the storage related to the hook will be reported; this may be overridden by specifying the name of the storage as reported by storage-list, and must be specified for non-storage hooks.
storage-get can be used to identify the storage location during storage-attached and storage-detaching hooks. The exception to this is when the charm specifies a static location for singleton stores.
