The Open Policy Agent (OPA) is widely known for enforcing security policies, but its capabilities extend far beyond compliance. This session explores how OPA can be harnessed for FinOps practices in Kubernetes. Learn how to create policies to enforce cost-efficient resource requests, limit the use of high-cost instance types, and ensure workloads adhere to budget constraints. Discover how to integrate OPA with tools like Gatekeeper and OpenCost to provide real-time cost visibility and actionable insights. Through practical examples, attendees will gain the skills to use OPA for both security and cost optimization in Kubernetes environments.
