Container Registry Limits

The DigitalOcean Container Registry (DOCR) is a private Docker image registry that lets you store and manage private container images. DOCR integrates natively with Docker environments and DigitalOcean Kubernetes 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.

  • You cannot upload images over 2 GB to a container registry.
