About This Architecture

OpenShift cluster with dual-namespace architecture spanning subnets 10.0.1.0/24 and 10.0.2.0/24, featuring a Control Plane managing API Server and etcd, plus Ingress routing to ClusterIP and NodePort Services. Namespace-1 hosts app-frontend and app-backend Pods with Deployment, ReplicaSet, and HPA controllers, while namespace-2 runs worker Pods with PersistentVolume attachment and NetworkPolicy enforcement. This multi-namespace design demonstrates resource isolation, RBAC boundaries via ServiceAccounts, and production-grade traffic management for microservices. Fork and customize this diagram on Diagrams.so to model your own OpenShift topology, adjust CIDR ranges, or add additional namespaces and workload tiers. The architecture exemplifies best practices for namespace-scoped resource governance and network segmentation in enterprise Kubernetes deployments.

People also ask

How do I design an OpenShift cluster with multiple namespaces, Ingress routing, and network policies for microservices?

This diagram shows a production OpenShift cluster spanning two namespaces (10.0.1.0/24 and 10.0.2.0/24) with a Control Plane managing API Server and etcd, Ingress routing external traffic to ClusterIP and NodePort Services, and Deployments with ReplicaSets and HPA for auto-scaling. NetworkPolicy and ServiceAccounts enforce isolation and least-privilege access across namespaces.
