Learning DevOps

By: Mikael Krief

Overview of this book

The implementation of DevOps processes requires the efficient use of various tools, and the choice of these tools is crucial for the sustainability of projects and collaboration between development (Dev) and operations (Ops). This book presents the different patterns and tools that you can use to provision and configure an infrastructure in the cloud. You'll begin by understanding DevOps culture, the application of DevOps in cloud infrastructure, provisioning with Terraform, configuration with Ansible, and image building with Packer. You'll then be taken through source code versioning with Git and the construction of a DevOps CI/CD pipeline using Jenkins, GitLab CI, and Azure Pipelines. This DevOps handbook will also guide you in containerizing and deploying your applications with Docker and Kubernetes. You'll learn how to reduce deployment downtime with blue-green deployment and the feature flags technique, and study DevOps practices for open source projects. Finally, you'll grasp some best practices for reducing the overall application lead time to ensure faster time to market. By the end of this book, you'll have built a solid foundation in DevOps, and developed the skills necessary to enhance a traditional software delivery process using modern software delivery tools and techniques

Integration of Newman in the CI/CD pipeline process

Newman is a tool that automates the execution of Postman requests from the command line, which will quickly allow us to integrate it into a CI/CD pipeline.

To simplify its integration into a pipeline, we go to the first step in the directory that contains the JSON files that were exported from Postman, and create an npm configuration file—package.json.

This will have the following content:

"name": "postman",
"version": "1.0.0",
"description": "postmanrestapi",
"scripts": {
"testapilocal": "newman run DemoBook.postman_collection.json -e Local.postman_environment.json -r junit,cli --reporter-junit-export result-tests-local.xml",
