Containerization with LXC

By: Konstantin Ivanov

Overview of this book

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.

Chapter 2. Installing and Running LXC on Linux Systems

LXC takes advantage of the kernel namespaces and cgroups to create process isolation we call containers, as we saw in the previous chapter. As such, LXC is not a separate software component in the Linux kernel, but rather a set of userspace tools, the liblxc library, and various language bindings.

In this chapter, we'll cover the following topics:

  • Installing LXC on Ubuntu and CentOS using distribution packages

  • Compiling and installing LXC from source code

  • Building and starting containers using the provided templates and configuration files

  • Manually building the root filesystem and configuration files using tools such as debootstrap and yum
