ReferencedResourceNotFound	analysis-message

This message occurs when an Istio resource references another resource that does not exist. This will lead to errors when Istio tries to look up the referenced resource but cannot find it.

For example, you receive this error:

{{< text plain >}} Error [IST0101] (VirtualService httpbin.default) Referenced gateway not found: "httpbin-gateway-bogus" {{< /text >}}

In this example, the VirtualService refers to a gateway that does not exist:

{{< text yaml >}} apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: name: httpbin-gateway spec: selector: istio: ingressgateway servers:

• port: number: 80 name: http2 protocol: HTTP2 hosts:
  • "*"

---

apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: httpbin spec: hosts:

• "*" gateways:
• httpbin-gateway-bogus # Should have been "httpbin-gateway" http:
• route:
  • destination: host: httpbin-gateway {{< /text >}}

To resolve this problem, look for the resource type in the detailed error message, correct your Istio configuration and try again.
