Working on a CI/CD platform and seeing how real teams actually build their apps, I can tell you that the majority are still not using containers. It ain't easy. It changes the entire build/test/deploy process. But it is the best way to build for the cloud. So we wrote this book for developers who need to GTD. You'll learn just enough to start using Docker and Kubernetes in production — in days, not weeks or months. The book is also open source on GitHub: https://github.com/semaphoreci/b... I'd love to hear your feedback, and any particular questions or struggles you've had while transitioning to containers. ✌️
