ArgoCD Notifications#

ArgoCD Notifications is a built-in component (since ArgoCD 2.5) that monitors applications and sends alerts when specific events occur – sync succeeded, sync failed, health degraded, new version deployed. Before notifications existed, teams polled the ArgoCD UI or built custom watchers. Notifications eliminates that.

Architecture#

ArgoCD Notifications runs as a controller alongside the ArgoCD application controller. It watches Application resources for state changes and matches them against triggers. When a trigger fires, it renders a template and sends it through a configured service (Slack, Teams, webhook, email, etc.).
