You can add a Registry so that you can access images for your Marketplace applications.

A registry is a repository of containers for storing and delivering application images.

Belden Horizon Data Operations supports Docker Registry v2.

Currently, these registries are available:

- AWS ECR
- Azure Container
- Docker
- GCR Docker

Each registry uses different configuration information.

To enable retrieval of applications from containers, you first must give Belden Horizon Data Operations access to the repository.

**Note**: If you add a registry for Azure in Docker configuration with a username/password, the format is `https://<your-registry-name>.azurecr.io/v2/`.&#x20;
