Argo CD Install: Helm-Based Setup for Enterprise DevOps Team

Argo CD, a Kubernetes-native continuous delivery controller, is designed for enterprises to standardize GitOps—a model where Git serves as the source of truth, enabling a pull-based reconciliation loop that ensures cluster states align with Git declarations. This guide describes installing Argo CD using Helm for version control and predictable upgrades, emphasizing secure access with SSO, RBAC, and multi-team AppProjects for safe GitOps adoption. It outlines installing Argo CD as a shared infrastructure with high availability, monitoring, and backup plans to maintain reliability at scale. The installation process involves choosing between Helm for repeatable, audit-friendly setups or upstream manifests for quick evaluations, and it highlights the importance of stable operations through version pinning, ingress configuration, and TLS management. Enterprise practices stress the significance of monitoring, backup strategies, and controlled upgrades, treating Argo CD as a foundational platform infrastructure rather than a mere tool, with a focus on high availability and operational maturity for shared dependency management.
