Enterprise Java CI/CD with GitOps & Observability
Jenkins builds, Argo CD reconciliation, Grafana dashboards
Overview
A GitOps delivery model for enterprise Java services. Jenkins handles build and image publishing, Argo CD continuously reconciles the cluster against the desired state in Git, and Prometheus with Grafana provides the metrics and dashboards that make each rollout observable rather than hopeful.
Engineering focus
Git is the source of truth, so drift correction is automatic — which means the manifests repository needs the same review discipline as application code.
