Why are so many companies adopting GitOps for their DevOps and cloud native strategy? This reliable framework is quickly becoming the standard method for deploying apps to Kubernetes. With this practical, developer-oriented book, DevOps engineers, developers, IT architects, and SREs will learn the most useful recipes and examples for following GitOps practices. Through their years of experience in application modernization, CI/CD, and automation, authors Alex Soto Bueno and Natale Vinto from Red Hat walk you through all the steps necessary for successful hands-on application development and deployment with GitOps. Once you start using the recipes in this book, you'll have a head start in development cycles on Kubernetes following the GitOps approach. You'll learn how to: Develop and deploy applications on Kubernetes Understand the basics of CI/CD and automation on Kubernetes, and apply GitOps practices to implement development cycles on the platform Prepare the app for deployment on multiple environments and/or multiple Kubernetes clusters Deploy apps for either multiple environments using GitOps and Argo CD, or for Kubernetes clusters Create Kubernetes-native pipelines with Tekton Provide and extend DevOps skills for the team working on Kubernetes Use progressive delivery to put your applications into production

Optimized for Kubernetes, Quarkus is designed to help you create Java applications that are cloud first, container native, and serverless capable. With this cookbook, authors Alex Soto Bueno and Jason Porter from Red Hat provide detailed solutions for installing, interacting with, and using Quarkus in the development and production of microservices. The recipes in this book show midlevel to senior developers familiar with Java enterprise application development how to get started with Quarkus quickly. You’ll become familiar with how Quarkus works within the wider Java ecosystem and discover ways to adapt this framework to your particular needs. You’ll learn how to: Shorten the development cycle by enabling live reloading in dev mode Connect to and communicate with Kafka Develop with the reactive programming model Easily add fault tolerance to your services Build your application as a Kubernetes-ready container Ease development with OpenAPI and test a native Quarkus application

With the Ansible automation tool, developers and system administrators in the enterprise can automate the provisioning, configuration, and management of distributed and on-premises systems. This study guide prepares you for the Red Hat Certified Engineer (RHCE) certification exam, 90% of which covers Ansible. Alex Soto Bueno, director of developer experience at Red Hat, and Andrew Block, Distinguished Architect at Red Hat, walk you through all the material covered in the exam. You'll begin with foundational concepts that build on one another and then dive into specific exam topics. The performance-based exam requires a deep knowledge of Ansible systems and tasks under time pressure. This comprehensive guide is the ideal way to prepare. With this book, you will: Learn how Ansible can simplify your day-to-day operations Solve real-world Ansible problems in a hands-on command-line environment Learn how to install Ansible and set up managed environments Use ad hoc commands and include them in scripts as requested in the exam Prepare your Ansible configuration file and inventory file Install virtualization software Set up and prepare nodes, including SSH key-based authentication Install required Ansible packages And more

Safely manage your secret information like passwords, keys, and certificates in Kubernetes. This practical guide is full of best practices and methods for adding layers of security that will defend the critical data of your applications. In Kubernetes Secrets Management you will find: Strategies for storing secure assets in Kubernetes Cryptographic options and how to apply them in Kubernetes Using the HashiCorp Vault server on Kubernetes for secure secrets storage Managing security with public cloud providers Applying security concepts using tools from the Kubernetes ecosystem End-to-end secrets storage from development to operations Implementing in Kubernetes in CI/CD systems Secrets, like database passwords and API keys, are some of the most important data in your application. Kubernetes Secrets Management reveals how to store these sensitive assets in Kubernetes in a way that’s protected against leaks and hacks. You’ll learn the default capabilities of Kubernetes secrets, where they’re lacking, and alternative options to strengthen applications and infrastructure. Discover a security-first mindset that is vital for storing and using secrets correctly, and tools and concepts that will help you manage sensitive assets such as certificates, keys, and key rotation. About the technology Kubernetes relies on passwords, tokens, keys, certificates, and other sensitive information to keep your system secure. But how do you keep these “secrets” safe? In this concise, practical book you’ll learn secrets management techniques that go far beyond the Kubernetes defaults. About the book Kubernetes Secrets Management reveals security best practices and reliable third-party tools for protecting sensitive data in Kubernetes-based systems. In this focused guide, you’ll explore relevant, real-world examples like protecting secrets in a code repository, securing keys with HashiCorp Vault, and adding layers to maintain protection after a breach. Along the way, you’ll pick up secrets management techniques you can use outside Kubernetes, as well. What's inside Cryptographic options you can apply in Kubernetes Managing security with public cloud providers Secrets storage, from development to production End-to-end Kubernetes secrets management in CI/CD systems About the reader For readers experienced with Kubernetes and CI/CD practices.

Summary Testing Java Microservices teaches you to implement unit and integration tests for microservice systems running on the JVM. You'll work with a microservice environment built using Java EE, WildFly Swarm, and Docker. You'll learn how to increase your test coverage and productivity, and gain confidence that your system will work as you expect. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology Microservice applications present special testing challenges. Even simple services need to handle unpredictable loads, and distributed message-based designs pose unique security and performance concerns. These challenges increase when you throw in asynchronous communication and containers. About the Book Testing Java Microservices teaches you to implement unit and integration tests for microservice systems running on the JVM. You'll work with a microservice environment built using Java EE, WildFly Swarm, and Docker. You'll advance from writing simple unit tests for individual services to more-advanced practices like chaos or integration tests. As you move towards a continuous-delivery pipeline, you'll also master live system testing using technologies like the Arquillian, Wiremock, and Mockito frameworks, along with techniques like contract testing and over-the-wire service virtualization. Master these microservice-specific practices and tools and you'll greatly increase your test coverage and productivity, and gain confidence that your system will work as you expect. What's Inside Test automation Integration testing microservice systems Testing container-centric systems Service virtualization About the Reader Written for Java developers familiar with Java EE, EE4J, Spring, or Spring Boot.
