Summary

In this chapter, we covered some basic concepts of Docker containers starting from how we can think about the difference between containers, virtual machines, and processes. We also learned how to create virtual machines on Azure that serve as Docker hosts. We went on and learned about basic Docker concepts like images, containers, data volumes, Dockerfiles, and layers. Throughout the chapter, we also familiarized ourselves with basic Docker commands. As we have seen, containers are a powerful technology that can make us rethink how we build applications in the future.

Over the next chapters, we will use this knowledge to dive deeper into how to work with containers and how to build microservices architectures on top of containers.
