Book Description

Get a novel perspective on Linux containers and understand the world of virtualization. This book takes you down the rabbit hole to discover what lies below the API. You’ll go on a journey of virtualization and see how containers are realized in the Linux world. Linux Containers and Virtualization details the data structures within the Linux kernel which make up Linux containers. You will start with the fundamentals of virtualization including how different resources such as memory, CPU, network, and storage are virtualized. Then you will move on to hypervisors and virtualization using the Kernel virtual Machine (KVM) and Quick Emulator (QEMU). Next, you will learn about Linux namespace, cgroups, and layered file systems, which are the essential building blocks of Linux containers. The explanation traverses the Linux kernel codebase to show how these are realized in the Linux kernel. In the final chapter, you will code your own container by applying the concepts learnt in the previous chapters. On completion of the book, you will have the knowledge to start coding a Linux container.

Book Description

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.

Book Description

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.
