Containerization with LXC

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.

Summary


In this chapter, we looked at an example of a basic OpenStack deployment using only the identity service Keystone for storing a catalog of services, and authentication and authorization, the Nova compute services for provisioning the LXC instance, the image service Glance, which stores the LXC container images, and the networking services with Neutron that created the bridge and assigned the IP address to our container.

A full production-ready deployment would consist of multiple controller nodes that run the aforementioned services, along with a pool of compute servers to provision the containers on.

OpenStack with LXC is a great way to create and manage multitenant cloud environments, running various software applications in a centralized and highly scalable way.
