## Where is my data?
By default, your registry stores its data on the local filesystem, inside the container.
In a production environment, it's highly recommended to use [another storage backend](https://github.com/docker/distribution/blob/master/docs/storagedrivers.md), by [configuring it](https://github.com/docker/distribution/blob/master/docs/configuration.md#storage).
If you want to stick with the local posix filesystem, you should store your data outside of the container.
This is achieved by mounting a volume into the container:
$ docker run -d -p 5000:5000 \
-e REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/var/lib/registry \
-v /myregistrydata:/var/lib/registry \
--restart=always --name registry registry:2
