Summary
In this chapter, we described the knowledge that is gained in the post-implementation phases, primarily regarding the operational aspect of the Docker containers. We started the chapter by clarifying important terms, such as images, containers, registry, and repository, in order to enable you to acquire an unambiguous understanding of the concepts illustrated thereafter. We explained how to search for the images in the Docker repository. We also discussed the operation and handling of the Docker containers, how to track the changes inside the containers, how to control and housekeep the containers. In an easy-to-grasp manner, we will explain the process of the Docker image building in the next chapter.
