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

Architecture


In this section, we will see the OpenStack architecture using Kolla. The following figure shows a highly available (HA) OpenStack multimode setup done by Kolla.

The infrastructure engineering here means the code or application written for infrastructure management. The code is submitted to Gerrit for review and then the CI system reviews and checks for correctness of the code. Once the code is approved by CI, the CD system feeds the output of build, that is the OpenStack containers that are based on Kolla, into a local registry.

After this, the Ansible contacts Docker and launches our OpenStack multinode environment with HA:
