Vultr Container Registry is a managed storage and distribution system for Open Container Initiative (OCI) images or related artifacts. You can securely host multiple container images, build and deploy your applications on platforms such as Docker or Kubernetes.

A Vultr Container Registry contains multiple repositories that match your main repository name. For instance, a registry name example creates repository names with the format example/container-name. In addition, every container image you push to the registry creates a new repository tag you can pull and distribute on your target platforms.
