Podman in Action
The next generation of containers is here. Learn Podman directly from its creator, discover its exceptional security features, and start managing rootless containers that integrate easily into your systems. In Podman in Action you will learn how to: Build and run containers in rootless mode Develop and manage pods Use SystemD to oversee a container’s lifecycle Work with the Podman service via Python Keep your containers confined using Podman security features Manage containerized applications on edge devices Podman in Action shows you how to deploy containerized applications on Linux, Windows, and MacOS systems using Podman. Written by Daniel Walsh, who leads the Red Hat Podman team, this book teaches you how to securely manage the entire application lifecycle without human intervention. You’ll quickly get to grips with Podman’s unique advantages over Docker, and learn how easy it is to migrate your Docker-based infrastructure. It also demonstrates how, with Podman, you can easily convert containerized applications into Kubernetes-based microservices. About the technology It’s time to upgrade your container engine! The Podman container manager delivers flexible image layer control, seamless Kubernetes compatibility, and rootless containers that can be created, run, and managed by users without admin rights. Plus, its OCI-compliant support for the Docker API lets you shift existing containers to Podman without breaking your scripts or changing the way you work. About the book Podman in Action introduces the Podman container manager. The easy-to-follow explanations and examples give you a clear view of what containers are, how they work, and how to manage them using Podman’s powerful features. You’ll get a deep look at the Linux components Podman uses and even learn more about Docker along the way. You’ll especially appreciate author Dan Walsh’s unique insights into container security.

Build resilient and scalable, cloud-native enterprise Java applications using the Quarkus framework. Quarkus lets you live-reload your Java code, deliver continuous background testing, and automatically provide database instances—plus tons more productivity-boosting features! Quarkus in Action quickly gets you up to speed with Quarkus by building a real-world business application. In Quarkus in Action, you will: • Use Quarkus Dev mode to speed up and enhance Java development • Understand how to use the Dev UI to observe and troubleshoot running applications • Automatic background testing using the Continuous Testing feature • New frameworks and libraries such as Quarkus Messaging, gRPC, and GraphQL • Simplify deployment of applications into Kubernetes and OpenShift • Automatic management of remote services such as databases and message brokers via Docker containers • Set up observability for applications by using metrics, health checks and distributed tracing Quarkus in Action is written by Martin Štefanko and Jan Martiška, Red Hat engineers who are both active contributors to the Quarkus project. In it, you’ll learn how Quarkus works and how you can integrate it into your stack for more productive Java development. Discover what makes Quarkus different from classic enterprise Java frameworks, how Quarkus streamlines creating cloud-native applications, and makes deployment easy. Foreword by Markus Eisele. Purchase of the print book includes a free eBook in PDF and ePub formats from Manning Publications. About the technology Choose a Java framework that’s as modern as your applications! Quarkus is a cloud-first framework designed for speed and cost optimization. It’s Kubernetes-aware by default and includes amazing productivity features like live reloading, continuous testing, and a developer-friendly UI that lets you code fluidly without tedious setup. About the book Quarkus in Action provides a carefully designed learning path through Quarkus’ key features and use cases. You’ll learn hands-on by implementing a working car rental application with a cloud-native microservices design that includes Kubernetes, SQL and NoSQL databases, messaging, and observability. Along the way, you’ll learn how Quarkus simplifies deployment on cloud platforms like OpenShift. What's inside • Speed up development with Quarkus Dev mode • Troubleshoot running apps with Dev UI • Continuous testing in the background • Automatic startup of development databases About the reader For intermediate Java developers who have experience deve- loping server-side Java applications.
