Adding container registries

The Container Registries page lets administrators record and manage information about public and private Docker container registries, including the registry location and access credentials. These registries can then be used to create containers directly from the Skytap web interface.

Admin container registries

By default, Skytap includes the Public Docker Hub registry, which can be used to download and install common Docker images, such as web servers and databases. The administrator can add other registries, including private registries.

Notes

  • You can have a maximum of 500 registries for your account.
  • For more information about Docker registries, see Docker Registry.
  • The Docker Hub registry is available at index.docker.io.
