With the development of Internet technology and the popularity of cloud computing technology, the organizations or companies try to build a private cloud platform. PaaS is a form of cloud computing service resources and provides application development environment. As the existing PaaS platform hosting and virtual machine environment simplification of the problem of excessive consumption of resources, we have conducted in-depth research on the PaaS platform in this paper. We propose a mechanism to create PaaS platform based on Docker [8]. Docker provides a running application solutions and is built on a lightweight virtualization LXC container [3]. We also develop a dashboard to facilitate users operations. Even though users do not know the professional knowledge of cloud, they can easily deploy their application.
