 Kubero [pronounced: Kube Hero] is a self-hosted PaaS (Platform as a Service) that allows any developer to deploy their application on Kubernetes without specialized knowledge. Kubero follows the principles of 12-factor apps. It is possible to run apps based on existing containers or from source code.
