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

Efforts within the OpenStack community to support containers


OpenStack provides the following:

  • Compute resources
  • Multi-tenant security and isolation
  • Management and monitoring
  • Storage and networking

The preceding mentioned services are needed for any cloud/data center management tool regardless of which containers, virtual machines, or bare metal servers are being used. Containers complement existing technology and bring a new set of benefits. OpenStack provides the support to run containers on bare metal or virtual machines.

In OpenStack, the following projects have taken initiative or provided support for containers and related technologies.

Nova

Nova is a compute service for OpenStack. Nova provides APIs to manage virtual machines. Nova supports the provisioning of machine containers using two libraries, that is, LXC and OpenVZ (Virtuozzo). These container related libraries are supported by libvirt, which Nova uses to manage virtual machines.

Heat

Heat is an orchestration service for OpenStack....
