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

Summary


In this chapter, we learned about the OpenStack container management service, Zun. We looked into the different objects in Zun. Then, we also learned about the components and the architecture of Zun. The chapter also provided a detailed overview of the workflow of a user request to manage containers in Zun. Then, we looked at how to install a development setup in Zun using DevStack, and we did a hands-on exercise using Zun CLI to create a container and start and stop various other operations on containers. In the next chapter, we will learn about Kuryr, which provides the networking resources to containers using Neutron.
