Discover Podman, a next-generation container engine that manages containers rootlessly and provides extra layers of exceptional security unavailable in Docker and other container platforms.
In Podman in Action
you will learn how to:
Podman in Action
- 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
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. It also demonstrates how, with Podman, you can easily convert containerized applications into Kubernetes-based microservices.
about the technology
Podman is a daemonless container engine that lets you build and run containers on all Linux distributions, Windows, and MacOS. It supports the fork exec model for running containers, which allows for better integration with a system and makes it easier to run rootless. It also boasts unique advanced features, such as the ability to create and run Pods that are similar to Kubernetes, and execute Kubernetes YAML. And if you’re not ready to completely move on from Docker, Podman can run as a service and support the Docker API in a way that works with docker-compose and docker-py.
about the book
Podman in Action
teaches you how to develop and manage rootless containers using Podman. 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. Every chapter includes easy-to-follow examples, including steps to deploy a complete containerized web service. You’ll learn the power and security of the user namespace, how to install and run Podman on MacOS and Windows, and dive into key security concepts like SELinux and SECCOMP.
