Learning DevOps - Second Edition

By: Mikael Krief

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.

Shifting security left with DevSecOps

As we discussed in Chapter 14, Security in the DevOps Process with DevSecOps, security and compliance analyses must be part of DevOps processes. However, in companies, there is often a lack of awareness among development teams about security rules, and this is why security is implemented too late in DevOps processes.

To integrate security into processes, it is, therefore, necessary to raise awareness among developers of aspects of application code security, but also of the protection of CI/CD pipeline configuration.

In addition, it is also necessary to eliminate the barrier between DevOps and security by integrating security teams more often into the various meetings that bring together Dev and Ops teams, thus ensuring better consistency between developers, operational teams, and also security. Regarding the choice of tools, don't use too many different tools, because the goal is for these tools to also be used by developers and be...
