About This Book

• Get the most practical and up-to-date resource on LXC and take full advantage of what Linux containers can offer in the day-to-day operations of large-scale applications
• Learn how to deploy and administer various workloads such as web applications inside LXC
• Save your organization time and money by building robust and secure containers and by speeding the deployment process of your software

Who This Book Is For

This book is for Linux engineers and software developers who are looking to deploy applications in a fast, secure, and scalable way for use in testing and production.

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.
