Containers in OpenStack

Overview of this book

Containers are one of the most talked about technologies of recent times. They have become increasingly popular as they are changing the way we develop, deploy, and run software applications. OpenStack gets tremendous traction as it is used by many organizations across the globe and as containers gain in popularity and become complex, it’s necessary for OpenStack to provide various infrastructure resources for containers, such as compute, network, and storage. Containers in OpenStack answers the question, how can OpenStack keep ahead of the increasing challenges of container technology? You will start by getting familiar with container and OpenStack basics, so that you understand how the container ecosystem and OpenStack work together. To understand networking, managing application services and deployment tools, the book has dedicated chapters for different OpenStack projects: Magnum, Zun, Kuryr, Murano, and Kolla. Towards the end, you will be introduced to some best practices to secure your containers and COE on OpenStack, with an overview of using each OpenStack projects for different use cases.

Preface

Chapter 4. Containerization in OpenStack

This chapter starts by explaining the need for containers in OpenStack. Then, it also explains the different processes going on inside OpenStack to support containers.

Containers are a pretty hot topic today. Users want to run their production workloads on containers along with virtual machines. They are popular for the following reasons:

  • Containers provide immutable infrastructure models using the concept of packaging
  • It's easy to develop and run microservices using containers
  • They facilitate quicker development and testing of applications

The Linux kernel has supported containers for several years. Microsoft also recently started to support containers in the form of Windows Server containers and Hyper-V containers. As containers have evolved over time, so has OpenStack support for containers. OpenStack provides APIs to manage containers and their orchestration engines within the data centers.

In this chapter, we will discuss how OpenStack and containers...
