Use Linux containers as an alternative virtualization technique to virtualize your operating system environment. This book will cover LXC’s unmatched flexibility with virtualization and LXD’s smooth user experience. Practical LXC and LXD begins by introducing you to Linux containers (LXC and LXD). You will then go through use cases based on LXC and LXD. Next, you will see the internal workings of LXC and LXD by considering the repositories and templates used. You will then learn how to integrate LXC and LXD with common virtualization and orchestration tools such as libvirt and SaltStack. Finally, you will dive into containerization and security. The book will explore some of the common problems in security and provide a case study on how containerization can help mitigate some of the operating system-level security issues in an IoT environment. What You Will Learn Get an introduction to Linux containers Discover the basics of LXC and LXD See use cases that can be solved with LXC and LXD – for developers, devops, and system administrators Master LXC and LXD repositories Use LXC and LXD with common virtualization and orchestration tools Consider a containerization and security in IoT case study Who This Book Is For The audience for this book should have basic knowledge of Linux and software development in general. The intended readership is primarily software developers, operations engineers, and system administrators who are interested in devops, though managers and enthusiasts will also benefit from this book.

The book covers internals of virtualization, types of virtualization from vm based to container based virtualization. It also covers other alternate means of virtualization. The book starts from covering basics of virtualization and how its realized in terms of how packet flow happens when a network request is made from a VM. The book then starts to focus on the containerized form of virtualization and how this is realized in the Linux kernel. The different data structures within the Linux Kernel which facilitate this form of virtualization are discussed . It entails the 3 pillars of containerization namely namespaces, cgroups and layered filesystem. The book goes into details of how namespaces are realized within the linux kernel and which data structures help in providing this isolation. Then the book talks about cgroups are realized within kernel with example of couple of cgroup controllers. It covers how layered filessystem is created and whats its purpose with examples. Once the conceptual understanding is developed, the book moves on to explanation of how one can create their own container. The book then covers in depth with examples on how various namespaces are realized with explanation of individual namespaces like pid, usernamespace and in particular the network namespace. Finally a user can see his own container working with all the namespaces and packet flow happening between host and container. The book finally covers code to create own cgroups within the container and takes some example to apply cgroups within your own container runtime. The basic theme of the book is to give the user an idea of how virtualization is being done in cloud today and what all options exist for the same. The book then details out how container eco systems work today and finally peels the different layers of containers and enables user to create his own container runtime like Docker.

This book is a practical, comprehensive guide to creating secure and efficient Linux containers using the Rust programming language. It utilizes a hands-on approach to teach Rust's programming constructs, security features, and its application in containerization. Author Shashank Mohan Jain starts with a gentle introduction to Rust to help you grasp the language's core concepts, syntax, and unique memory safety guarantees. He then transitions into the realm of Linux container development, where Rust shines as a robust and secure language for building containerized applications. Through hands-on examples, you will gain a deep understanding of how to harness Rust's features to create lightweight and secure Linux containers and how to leverage its strong type system and ownership model to eliminate common bugs and ensure memory safety in containerized applications. As you progress, you’ll explore the intricacies of working with system resources, networking, and interacting with the host operating system while maintaining isolation and security within the containers, as well as how Rust's concurrency model can build performant and responsive containerized applications. The book also covers advanced topics such as secure configuration handling, logging, and handling authentication within your containerized environment. After completing this book, you will be well-versed in Rust programming, equipped to create efficient and secure Linux containers, and confident in your ability to develop containerized applications for a variety of use cases. What You Will Learn Understand the basics of the Rust programming language Understand Rust's security features Create Linux constructs like namespaces in Rust Develop your own container runtime using Rust Who This Book Is For Developers, Architects and SREs working with cloud applications and dealing with container based workloads.

What You Will Learn Deep dive into the foundations of Linux containers with kernel namespaces and cgroups Install, configure, and administer Linux containers with LXC and libvirt Begin writing applications using Python libvirt bindings Take an in-depth look at container networking Set up monitoring and security with LXC Build and deploy a highly available application with LXC in the cloud In Detail In recent years, containers have gained wide adoption by businesses running a variety of application loads. This became possible largely due to the advent of kernel namespaces and better resource management with control groups (cgroups). Linux containers (LXC) are a direct implementation of those kernel features that provide operating system level virtualization without the overhead of a hypervisor layer. This book starts by introducing the foundational concepts behind the implementation of LXC, then moves into the practical aspects of installing and configuring LXC containers. Moving on, you will explore container networking, security, and backups. You will also learn how to deploy LXC with technologies like Open Stack and Vagrant. By the end of the book, you will have a solid grasp of how LXC is implemented and how to run production applications in a highly available and scalable way. Style and approach A practical guide that introduces the core technologies behind Linux containers and provides a deep dive into installation, configuration, and operations of LXC.
