Chapter 8. Using LXC with OpenStack
In previous chapters, we looked at examples of common design patterns that help autoscale services running inside LXC containers by leveraging tools such as Jenkins, custom REST-based APIs, and monitoring tools. In this chapter, we'll explore a fully automated way of provisioning LXC containers on a set of servers, using OpenStack.
OpenStack is a cloud operating system that allows for the provisioning of virtual machines, LXC containers, load balancers, databases, and storage and network resources in a centralized, yet modular and extensible way. It's ideal for managing a set of compute resources (servers) and selecting the best candidate target to provision services on, based on criteria such as CPU load, memory utilization, and VM/container density, to name just a few.
In this chapter, we'll cover the following OpenStack components and services:
Deploying the Keystone identity service, which will provide a central directory of users and services, and a...
