CNB provides hosting capabilities for common artifacts, where you can publish and share your artifacts.

Permission Control

In CNB, you can publish artifacts to specified repositories and share them based on repository visibility and permission controls.

The visibility of artifacts is consistent with the visibility of the repository they are published to. Authentication will use the user's repository permissions, with no need for additional artifact-specific configuration.

Resource	Action	Required Permission
Public Repository Artifacts	Pull	Anyone can pull, no authentication required
Public Repository Artifacts	Push	Repository Developer and above
Public Repository Artifacts	Delete	Repository Administrator and above
Private Repository Artifacts	Pull	Repository Guest and above, authentication required
Private Repository Artifacts	Push	Repository Developer and above
Private Repository Artifacts	Delete	Repository Administrator and above

CNB Artifact uses access tokens as authentication credentials. When logging in for artifact authentication, use 'cnb' as the username and your access token as the password. For example, using the Docker login command:

docker login docker.cnb.cool -u cnb -p {token-value}

Artifact Types

CNB currently supports the following artifacts:

Artifact Type	Domain
docker	docker.cnb.cool
helm	helm.cnb.cool

Storage Statistics

We charge based on the storage space occupied by your artifacts hosted on CNB. You can view the storage capacity used by each artifact in Repository-Usage Statistics.

Note: For Docker artifacts, duplicate base images are deduplicated when calculating storage capacity.
