appendHeaders feature: different header for different destination. #332

Open akyyy opened 6 years ago

akyyy commented 6 years ago

Is this a BUG or FEATURE REQUEST?: FEATURE REQUEST

What Version of Istio and Kubernetes are you using, where did you get Istio from, Installation details

istioctl version: 0.7.1
kubectl version: 1.9.6-gke.1

What happened: Since appendHeaders is a field for RouteRule Spec, the same headers are appended for all destinations. https://github.com/istio/api/blob/28cb7ff671111dbcc1f4ba86046d8dc46d437400/routing/v1alpha1/route_rule.proto#L158

What you expected to happen: We can append different headers for different destinations.

Feature Request: Y

@rshriram not sure if we want to do this via route-rule or whether this would move into an extension
