What We Learned From the Gateway API - Designing Linkerd's New Policy CRD

Explore the insights gained from the Gateway API in designing Linkerd's new Policy CRD in this 24-minute conference talk by Matei David from Buoyant, Inc. Delve into the world of policy attachment, a pattern introduced by the SIG Network community through the new Gateway APIs. Learn how Linkerd maintainers have leveraged this concept to enhance Linkerd's authorization mechanism. Discover the fundamentals of Gateway APIs, understand the concept of policy attachment, and see how it functions in real-world scenarios. Gain valuable knowledge about the revision of Linkerd's authorization policies, which now incorporate the policy attachment pattern. Understand how this approach allows for the creation of platform-level policies, such as timeouts, retries, and custom health checks, that can be attached to any Kubernetes type. Uncover the flexibility this brings to users, enabling them to develop custom policies that seamlessly integrate with the API rather than being hardcoded into it.
