Harden GKE clusters with Pulumi by applying infrastructure-as-code modules that enforce private clusters, Workload Identity, and network policies consistently across QAC, DEV, STG, and PRD environments.

Production GKE workloads require private clusters, Workload Identity, Binary Authorization, network policies, Pod Security Standards, and runtime security controls to ensure defense-in-depth and auditable configurations.

Yes, you can enforce Binary Authorization and network policies using Pulumi by deploying IaC templates that validate policies and establish secure-by-default configurations for your GKE clusters.

Yes, the guide supports environment promotion workflows for GKE by providing reference materials and example configurations to accelerate secure provisioning across QAC, DEV, STG, and PRD environments.

Yes, you need kubectl, gcloud, pulumi, and git installed to bootstrap a hardened GKE cluster following the guide’s environment-promotion workflow and apply the IaC templates.

Prevent GKE misconfigurations in infrastructure as code by using Pulumi-based policy validation and reference materials that enforce secure-by-default configurations across control plane, data plane, and runtime layers.
