Build CD pipelines following GitOps principles like declarative and immutable changes stored in version control all being continuously reconciled by Argo CD and minimize the failure of deployments

Key Features

Discover how to apply GitOps principles to build real-world CD pipelines
Understand Argo CD components and how they work together to reconcile cloud native applications
Learn to run Argo CD in production with declarative config changes, security, observability, disaster recovery, and more

Book Description

GitOps follows the practices of Infrastructure as Code (IaC) allowing developers to use their day-to-day tools and practices such as source control and pull requests to manage apps. With this book, youll understand how to apply GitOps bootstrap clusters in a repeatable manner, build CD pipelines for cloud native apps running on Kubernetes, and minimize the failure of deployments.

Youll start by installing Argo CD in a cluster, setting up user access using single sign-on, performing declarative configuration changes, and enabling observability and disaster recovery. Once you have a production-ready setup of Argo CD, youll explore how CD pipelines can be built using the pull method, how that increases security, and how the reconciliation process occurs when multi-cluster scenarios are involved. Next, youll go through the common troubleshooting scenarios, from installation to day-to-day operations and learn how performance can be improved. Later, youll explore the tools that can be used to parse the YAML you write for deploying apps. You can then check if it is valid for new versions of Kubernetes, verify if it has any security or compliance misconfigurations, or if it follows the best practices for cloud native apps running on Kubernetes.

By the end of this book, youll be able to build a real-world CD pipeline using Argo CD.
