A practical guide to hardening Oracle Kubernetes Engine (OKE) clusters for production using Terraform. Covers four key security layers: replacing overlay networks with OCI VCN-Native CNI for pod-level micro-segmentation, making the Kubernetes API server strictly private using an enhanced cluster, enabling AMD SEV memory encryption and shielded instances for hardware-level node security, and eliminating static credentials by adopting OCI IAM Workload Identity for short-lived cryptographic tokens. Together these form a zero-trust, defense-in-depth architecture suitable for financial and PII workloads.
