# Registry space

DCE 5.0 Container Registry provides a feature of isolating images based on registry spaces.
Registry spaces are divided into two types: public and private.

- Public registry: accessible by all users, usually storing public images. There is a default public registry space.
- Private registry: only authorized users can access, usually storing images of the registry space itself.

You can choose different instances to view all registry spaces underneath.

Click a name of registry space to view the current image list and retention rules for that space.
You can create retention rules for the current registry space. All retention rules are calculated
independently and apply to all qualified images, with a maximum of 15 retention rules supported.

After entering the registry space through the __Integrated Registry (Workspace)__ on the left navigation bar,
click the __Push command__ button located on the right side.

Click the __Upload image__ button to upload an image file in tar or tar.gz format.
Please note that the file size should not exceed 2 GB, and each file corresponds to one image.
Currently, only image compression packages made with container runtime v1.11.2 and above are supported to upload.
