End-to-end DevOps CI/CD pipeline integrating Jenkins for continuous integration, ArgoCD for GitOps-driven deployment, and Kubernetes with ROS2 workloads across staging and production namespaces. Developer commits trigger Jenkins workflows that execute OWASP scanning, SonarQube analysis, Trivy vulnerability checks, and Bandit security testing before containerization with Docker and image signing via Cosign and Syft. Validated images are pushed to Harbor Registry, then synced to a GitHub Deploy Repo where ArgoCD watches for changes and automatically deploys to Kubernetes staging with smoke tests and manual approval gates before production rollout. Production deployments include HPA scaling, NetworkPolicy enforcement on UDP 7400/7401 for ROS2 CycloneDDS communication, and comprehensive observability via Prometheus, Grafana, Loki, and Alertmanager with Slack notifications. This architecture demonstrates defense-in-depth security scanning, GitOps best practices, and production-grade monitoring for containerized robotics workloads. Fork and customize this diagram on Diagrams.so to match your Jenkins, ArgoCD, and Kubernetes versions or add additional security gates.
