Learning DevOps - Second Edition

Overview of this book

In the implementation of DevOps processes, the choice of tools is crucial to the sustainability of projects and collaboration between developers and ops. This book presents the different patterns and tools for provisioning and configuring an infrastructure in the cloud, covering mostly open source tools with a large community contribution, such as Terraform, Ansible, and Packer, which are assets for automation. This DevOps book will show you how to containerize your applications with Docker and Kubernetes and walk you through the construction of DevOps pipelines in Jenkins as well as Azure pipelines before covering the tools and importance of testing. You'll find a complete chapter on DevOps practices and tooling for open source projects before getting to grips with security integration in DevOps using Inspec, Hashicorp Vault, and Azure Secure DevOps kit. You'll also learn about the reduction of downtime with blue-green deployment and feature flags techniques before finally covering common DevOps best practices for all your projects. 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.

Summary

In this chapter, we introduced Postman, which is an excellent tool for testing APIs. We created a Postman account and installed it locally.

Then, we created collections and environments, in which we created requests that contain the settings of our APIs that are to be tested.

We also talked about automating these tests using the Newman command-line tool, with the exporting of Postman collections and environments.

Finally, in the last part of this chapter, we created and executed a CI/CD pipeline in Azure DevOps that automates the execution of API tests in a DevOps process.

In the next chapter, we will stay on the subject of testing, and we will look at the analysis of static code with a well-known tool called SonarQube.
