sigs.k8s.io/gateway-api@v1.0.0/site-src/reference/policy-attachment.md (about) 1 # Metaresources and Policy Attachment 2 3 The Gateway API defines a Kubernetes object that _augments_ the behavior of an object 4 in a standard way as a _Metaresource_. ReferenceGrant 5 is an example of this general type of metaresource, but it is far from the only 6 one. 7 8 Gateway API also defines a pattern called _Policy Attachment_, which augments 9 the behavior of an object to add additional settings that can't be described 10 within the spec of that object. 11 12 A "Policy Attachment" is a specific type of _metaresource_ that can affect specific 13 settings across either one object (this is "Direct Policy Attachment"), or objects 14 in a hierarchy (this is "Inherited Policy Attachment"). 15 16 This pattern is EXPERIMENTAL, and is described in [GEP-713](https://gateway-api.sigs.k8s.io/geps/gep-713/). 17 Please see that document for technical details.
