Abstract: In order to solve the problem of large deployment volume and low deployment efficiency of the application software of passenger information system, this article proposed a software deployment architecture based on Docker container technology. The article analyzed the advantages of container technology and designed the architecture model which combined with the traditional structure of passenger information system. The feasibility of this architecture was verified by the concrete implementation of mirror image production, container instantiation and warehouse privatization. The introduction of container technology solved many problems of traditional software deployment and provided technical support for the further cloud of passenger information system.
