Chapter 15. Running Docker Containers at Scale
Chapter 14 explained how containers are really just fancy Linux processes that, in the case of Docker, ship with all their dependencies using the Docker format. On a single system, processes are usually managed by the init system and the Linux kernel. However, how do we manage containers on multiple hosts? We need an orchestration solution that not only deploys containers; we need to handle other logistics such as intercontainer communication, container state management (for example, running, stopped, recover from failure), and so on. This chapter focuses on technologies that enable container management at scale across multiple hosts.
