This was the final chapter on our journey to becoming a Docker Certified Associate. We covered all the topics learned in previous chapters with some mock exam questions. As mentioned before, some of these questions are real questions posed in old exams.
The journey to becoming a Docker Certified Associate is not easy. We started this book from the very beginning, understanding why containers are so popular these days when we talk about microservices architectures. Then, we described how containers are executed using Docker Engine, integrating various isolation strategies to ensure security between container-embedded processes. As containers are based on images, we learned how to build and maintain them using Docker tools. We learned about different Docker objects and how to deploy applications using different networking methods, volumes, or security approaches.
