Summary

In this chapter, we studied the basic containerization concept with the help of application and OS-based containers. The differences between them explained in this chapter will clearly help developers to choose the containerization approach which fits perfectly for their system. We have thrown some light on the Docker technology, its advantages, and the lifecycle of a Docker container. The eight Docker design patterns explained in this chapter clearly show the way to implement Docker containers in a production environment. At the end of the chapter, the Unikernels concept was introduced which is the future of where the containerization domain is moving. In the next chapter, we will be starting with Docker installation troubleshooting issues and its deep pe resolutions.
