Container Registry Limits

The DigitalOcean Container Registry (DOCR) is a private Docker image registry with additional tooling support that enables integration with your Docker environment and DigitalOcean Kubernetes clusters. DOCR registries are private and co-located in the datacenters where DigitalOcean Kubernetes clusters are operated for secure, stable, and performant rollout of images to your clusters.

• Each DigitalOcean account can only create one registry, although a registry may contain multiple repositories.

• Registry names must be globally unique and not collide with the registry names of other users.

• Untagged images are not displayed in the control panel. However, you can delete untagged manifests using doctl and free up space in your registry.

• Manifest lists (for example, multi-arch images) are supported but may not display correctly in the control panel.

• You cannot change the datacenter region of a registry after creation.

• The name of a registry must:

  • Be unique across all DigitalOcean container registries.
  • Be no more than 63 characters in length.
  • Contain only lowercase letters, numbers, and/or hyphens.
  • Begin with a letter.
  • End with a letter or number.
