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

Introduction to Swift, the OpenStack object store


Swift is the object store service for OpenStack which can be used to store redundant, scalable data on clusters of servers that are capable of storing petabytes of data. It provides a fully distributed, API-accessible storage platform that can be integrated directly into applications or used for backup, archiving and data retention. Swift uses a distributed architecture with no central point of control, which makes it highly available, distributed and eventually a consistent object storage solution. It is ideal for storing unstructured data which can grow without bounds and can be retrieved and updated.

Data is written to multiple nodes that extend to different zones for ensuring data replication and integrity across the cluster. Clusters can scale horizontally by adding new nodes. In case of node failure, the data is replicated to other active nodes.

Swift organizes data in a hierarchy. It accounts for the stored list of containers, containers...
