'How do I route to 'cloud' hosted ingress if IoT hosted ingress fails to fetch data? (Kubernetes + istio gateway)
We have IoT edge hosted kubernetes environment. We also have a Kubernetes hosted 'cloud' environment. When an edge device makes a call onto the local kubernetes cluster on edge, it hits the local ingress and tries to fetch data from locally hosted API. But, there are some end points that are "cloud" only. This means, if a call comes into a route called "TradesAcrossRegions?Regionids=1,2", this call cannot hit the local API hosted on edge and must automatically go to our cloud hosted ingress. How do we configure these routing rules? We have plans to use istio service mesh + istio gateway for ingress on both edge device and cloud. I don't need the syntax on how to do this. Just some pointers and if this is possible will be great! Would it be possible to configure this route based on query params?
