Overview of this book

OpenStack is a very popular cloud computing platform that has enabled several organizations during the last few years to successfully implement their Infrastructure as a Service (IaaS) platforms. This book will guide you through new features of the latest OpenStack releases and how to bring them into production straightaway in an agile way. It starts by showing you how to expand your current OpenStack setup and how to approach your next OpenStack Data Center generation deployment. You will discover how to extend your storage and network capacity and also take advantage of containerization technology such as Docker and Kubernetes in OpenStack. Additionally, you'll explore the power of big data as a Service terminology implemented in OpenStack by integrating the Sahara project. This book will teach you how to build Hadoop clusters and launch jobs in a very simple way. Then you'll automate and deploy applications on top of OpenStack. You will discover how to write your own plugin in the Murano project. The final part of the book will go through best practices for security such as identity, access management, and authentication exposed by Keystone in OpenStack. By the end of this book, you will be ready to extend and customize your private cloud based on your requirements.

The Murano project defines a specific structure that should be used to develop and successfully publish an application in the catalog container. As we have explored in the previous chapter, a Murano application is simply a deployable package that includes a set of files in a ZIP format. Once uploaded to the catalog service, Murano unzips the package and runs a series of checks on the structure and presence of predefined files that we would expect to be present at different levels.

Let's break down the file tree and briefly parse the definition of each folder and file that Murano expects when uploading the .zip file:

  • manifest.yaml: This is a fixed file name that Murano expects as the first application entry point. The manifest file...
