Argo CD: GitOps Continuous Delivery for Kubernetes

by Shriira Press

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.
