This is the code repository for Argo CD in Practice, published by Packt.
The GitOps way of managing cloud-native applications
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, you’ll 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.
This book covers the following exciting features: Understand GitOps principles and how they relate to IaC Discover how Argo CD sets the background for reconciling Git state with the cluster state Run Argo CD in production with an emphasis on reliability and troubleshooting Bootstrap Kubernetes clusters with essential utilities following the GitOps approach Set up a CD pipeline and minimize the failure of deployments Explore ways to verify and validate the YAML you put together when working with Kubernetes Understand the democratization of GitOps and how the GitOps engine will enable its further adoption

Spiros Economakis started as a Software Engineer in 2010 and went through a series of jobs and roles from Software Engineer, Software Architect to Head of Cloud. In 2013 founded its own startup and that was the first touch with DevOps culture and built with a small team a couple of CI/CD pipelines for a microservice architecture and mobile apps releases. After this in most of the companies involved to influence DevOps culture and automation.
In 2019 started as an SRE in Lenses (acquired by Celonis) and soon influenced the organization with Kubernetes, GitOps, Cloud and transitioned to a position as Head of Cloud where he introduced GitOps across the whole company and used Argo CD for bootstrapping k8s clusters with utilities and continuous delivery applications. Now he works in an open-source company which is called Mattermost as a Senior Engineering Manager/SRE where he transformed the old GitOps approach (fluxcd) to GitOps v2.0 with Argo CD and built a scalable architecture for multi-tenancy.
Liviu Costea started as a developer in the early 2000 and his career path took him to different roles from Developer to Coding Architect and from Team Lead to CTO. In 2012 he transitioned to DevOps, when at a small company, someone had to start working on pipelines and automation because the traditional way wasn’t scalable anymore.
In 2018 he started with the Platform Team and then he was the Tech Lead in the Release Team at Mambu, where they designed most of the CI/CD pipelines, adopting GitOps practices. They have been live with Argo CD since 2019. More recently he joined Juni, a promising startup, where they are planning the GitOps adoption. For his contributions to OSS projects, including Argo CD, he was named CNCF Ambassador in August 2020.
