With the rapid development of cloud computing, virtualization technology as a key technology in cloud computing is also constantly evolving. Virtualization technology has faced a major challenges in the contradiction between application-to-application independence and resource interoperability. As a kind of virtual technology based on operating system, the container perfectly solved the problem of program independence and resource sharing.
