Docker discoveries

The Docker discoveries let you list the set of Docker images available from a registry, or pulled into an existing Docker deployment. The discovered Docker images can then be added to Cyberwatch with a grouped action for scanning.

Docker registries

Prerequisites

Docker discoveries need:

• A service account with permission to list all the registry artifacts

If you have a private Docker registry, and a service account able to enumerate its images catalog, you may create an asset discovery in Cyberwatch to list all the available present objects. However, only Docker images can be supervised by Cyberwatch.

To use the Docker images discovery, you need to add your Docker registry using the Stored credentials menu. You will then be able to add a Docker registry discovery from menu Discoveries, with clicking Add, then Docker registry in the Docker images category.

If the registry is properly configured, the discovery will list all the found registry artifacts.

Add the discovered Docker images

From the discovery assets list, you may see and filter the Docker images without any associated assets. To add them to Cyberwatch, pick the images you wish to scan and click Bulk actions > Scan as Docker images.

To scan an images, you will need a Docker engine. If you have not configured one yet, please refer to Add a Docker image.

Newly discovered Docker images can be automatically added to Cyberwatch as they are discovered. To enable this feature, you need to go to the discovery edition form and specify a Docker engine.

The registry is automatically selected based on the name of the discovered image. For instance, the image example.com/library/hello would automatically use the registry example.com, provided it has been added as a stored credential. New registries are automatically added as stored credentials, and you can manually edit them if they require authentication. You may in certain contexts select a preferred registry, but it will only be selected when the registry in the name of the discovered image matches the entry point of the registry.
