Hi,
I spent the last year and a half writing a book on Docker and microservices, which was finally released on O'Reilly this week.
"Using Docker: Developing and Deploying Software with Containers" takes a holistic approach, showing how containers can be used as the central artifact in a modern software development workflow. If anyone has any q's or feedback, please feel free to comment below.
The book is available at:
