Deploy to Kubernetes the GitOps way — make Git the source of truth and let Argo CD reconcile your clusters automatically.

Welcome to Argo CD: GitOps Continuous Delivery for Kubernetes.

Argo CD is the leading GitOps tool for Kubernetes: declare your desired cluster state in Git and let an in-cluster agent continuously reconcile reality to match it. This free book teaches it from the ground up — the GitOps model and pull-based delivery, Argo CD's architecture and reconciliation loop, the Application resource, sync status vs health and drift detection, Helm and Kustomize rendering, scaling to a fleet with App-of-Apps and ApplicationSets, sync waves, hooks and rollbacks, security with Projects, RBAC, SSO and secrets management, and operating Argo CD in production with HA, observability, and sound repo structure. Ten focused chapters with real manifests and clear diagrams that take you from concepts to running GitOps for real workloads.

This title is part of the ShriIra library and is free to read in full, right here — our small contribution to making world-class knowledge easy to reach.

A note on reading it: open the Contents menu at the top of the reader to jump between chapters, use the Aa menu to set a comfortable text size, theme (light, sepia, or night), and single- or two-page layout. Your place is saved automatically, so you can always pick up where you left off.

We hope it serves you well.
