Active DevOpsKubernetes Sandbox Architecture
Modular, multi-tier k3d cluster simulating production environments. Provisioned via Terraform across 4 layers with NGINX Ingress and Prometheus/Grafana observability stack.
// key_features
4-Layer Terraform Isolation
Infrastructure provisioned across 4 isolated layers using Terraform — each layer independently managed for modularity and safe teardown.
k3d Local Cluster
Lightweight k3d cluster (1 server + 2 agent nodes) simulating a production-grade multi-node Kubernetes environment on local hardware.
NGINX Ingress via Helm
Ingress controller deployed via Helm chart, enabling path-based and host-based routing across services within the cluster.
Full Observability Stack
Kube-Prometheus-Stack deployed for metrics collection and Grafana dashboards — real-time visibility into node health, pod status, and workload performance.
Zero-Trust Security Baseline
RBAC policies, isolated namespaces per workload, and dedicated ServiceAccounts enforcing least-privilege access across the cluster.
Production Simulation
Mirrors real production cluster behaviour — rolling updates, health probes, resource limits, and namespace-level isolation.
