Kubernetes has become the de facto standard for container orchestration, drastically improving how we deploy and manage cloud-native apps. Although it has simplified the lives of support professionals, we cannot say the same for developers who need to be equipped with better tools to increase productivity. An automated workflow that solves a wide variety of problems that every developer faces can make all the difference!Enter Skaffold – a command-line tool that automates the build, push, and deploy steps for Kubernetes applications.This book is divided into three parts, starting with common challenges encountered by developers in building apps with Kubernetes. The second part covers Skaffold features, its architecture, supported container image builders, and more. In the last part, you'll focus on practical implementation, learning how to deploy Spring Boot apps to cloud platforms such as Google Cloud Platform (GCP) using Skaffold. You'll also create CI/CD pipelines for your cloud-native apps with Skaffold. Although the examples covered in this book are written in Java and Spring Boot, the techniques can be applied to apps built using other technologies too.By the end of this Skaffold book, you'll develop skills that will help accelerate your inner development loop and be able to build and deploy your apps to the Kubernetes cluster with Skaffold.

This book is a fast-paced tutorial that explores the key features of EJB 3 with many accompanying examples. This book is not a complete reference guide, but a concise exploration of EJB 3's core elements. This book is primarily aimed at professional developers who already have a working knowledge of Java. Enterprise architects and designers with a background in Java would also find this book of use. Previous experience of working with Java is essential and knowledge of relational databases is desirable. As this book is an introduction to EJB 3, it is aimed at those who are new to EJB 3. As the new version of EJB is so radically different from the previous version (EJB 2.x), the book is suitable for and should be of interest to those who have had experience working with EJB 2.x. The text makes it clear where the differences between the versions of EJB lie, although they are not explored in detail.
