Viderum's cluster uses ckan-cloud-operator at https://github.com/ViderumGlobal/ckan-cloud-operator

Notable improvements and fixes in ckan-cloud-operator:

• Docker architecture improvements based on OKFN docker stack - https://github.com/okfn/docker-ckan - a more production-ready and stable docker image, used successfully for most production deployments.
• Centralized DB / SOLR / Storage - supports backup/restore, data migrations, custom initialization / configurationg
• Jenkins - running on Kubernetes with worker nodes running in separate ckan-cloud-operator pods, allowing to continuously deploy the operator code, and ensure consistent version is used in all clients.
• Routers - customizable routers management, supports SSL self-registration using Let's Encrypt
