--- description: Explains how to use the in-memory storage drivers keywords: registry, service, driver, images, storage, in-memory title: In-memory storage driver (testing only) --- For purely tests purposes, you can use the `inmemory` storage driver. This driver is an implementation of the `storagedriver.StorageDriver` interface which uses local memory for object storage. If you would like to run a registry from volatile memory, use the [`filesystem` driver](filesystem.md) on a ramdisk. **IMPORTANT**: This storage driver *does not* persist data across runs. This is why it is only suitable for testing. *Never* use this driver in production. ## Parameters None
