About This Architecture

OpenShift Platform Engineering Stack integrates ingress routing via HAProxy, GitOps automation through ArgoCD, identity management with Keycloak SSO, and persistent storage via Longhorn across three worker nodes. External users and developers authenticate through the Ingress Controller, which routes traffic to ArgoCD, Grafana, Gitea, and Argo Workflows namespaces, while CertManager handles TLS certificates and Bank-Vaults secures secrets. The control plane manages API Server, etcd, HPA scaling, NetworkPolicy, and RBAC through ServiceAccount and ClusterRole bindings. PostgreSQL Primary and Replica databases, managed by CNPG Operator, back Keycloak and Gitea, while Prometheus and Loki feed observability data to Grafana dashboards. This architecture demonstrates enterprise-grade platform engineering on OpenShift with declarative infrastructure, automated secret management, and comprehensive monitoring.
