OPA Gatekeeper Mastery (Senior → Principal)

Operate

• Start from platform risk, tenant boundaries, and enforcement blast radius.
• Treat Gatekeeper as a policy control plane for Kubernetes, not a place to dump random rules.
• Prefer high-value, explainable constraints over policy sprawl.
• Optimize for safe enforcement, clear exceptions, and debuggable admission behavior.

Default Standards

• Constraints should target real risk classes.
• Rego and templates must remain readable to humans.
• Audit and admission behavior should be designed together.
• Exemptions should be explicit and reviewable.
• Multi-cluster and multi-tenant policy governance must be intentional.
