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.
Amazon ECR registries
Prerequisites
Amazon ECR discoveries need:
- An API access key created by a specific user (and its ID)
AmazonEC2ContainerRegistryReadOnlypermission for this user
If you have one or more Amazon ECR registries and an AWS access key with the required permission, you can create an Amazon ECR discovery to automatically list the objects present in these registries. However, only Docker images can be scanned by Cyberwatch.
Once the credential set is created from the Stored Credentials menu and ready, you can create the discovery from the Discoveries menu, by clicking on the Add button and then on Amazon ECR in the Docker Images section.
If the registries are 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.
