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.

Introduction to Zun


Zun is an OpenStack service started in the Mitaka cycle developed by the members of the Magnum team. A decision was made at the OpenStack Austin Summit in 2016 to create a new project to allow for the management of containers and let the Magnum Container Infrastructure Management service manage only the infrastructure for running containers. The result was the Zun project.

Zun is a container management service for OpenStack that provides APIs to manage containers abstracted by different technologies at the backend. Zun supports Docker as the container runtime tool. Today, Zun integrates with many OpenStack services such as Neutron for networking, Glance for managing container images, and Cinder for providing volume to the containers.

Zun has various add-ons over Docker, which makes it a powerful solution for container management. Here is a list of some of the salient features of Zun:

  • Provides a standard API for the complete life cycle management of containers
  • Provides KeyStone...
