By: Bryan Feuling

Overview of this book

The world of software delivery and deployment has come a long way in the last few decades. From waterfall methods to Agile practices, every company that develops its own software has to overcome various challenges in delivery and deployment to meet customer and market demands. This book will guide you through common industry practices for software delivery and deployment. Throughout the book, you'll follow the journey of a DevOps team that matures their software release process from quarterly deployments to continuous delivery using GitOps. With the help of hands-on tutorials, projects, and self-assessment questions, you'll build your knowledge of GitOps basics, different types of GitOps practices, and how to decide which GitOps practice is the best for your company. As you progress, you'll cover everything from building declarative language files to the pitfalls in performing continuous deployment with GitOps. By the end of this book, you'll be well-versed with the fundamentals of delivery and deployment, the different schools of GitOps, and how to best leverage GitOps in your teams.

After an extensive search for alternatives to Argo CD, they discovered many different tools that all marketed themselves as GitOps tools or Argo CD alternatives.

The first on the list was Flux, which came from a company called Weaveworks. Weaveworks was actually the company that coined the term GitOps a few years ago and they built a tool that is similar to what Argo CD does. And, considering the developers are leveraging helm charts, WeaveWorks has also built out a helm operator to work with their Flux GitOps tool as well. However, the manifest requirements and the lack...
