Why am I unable to connect to the gRPC service exposed via an Ingress?
Issue description​
The gRPC service exposed by an Ingress is inaccessible.​
Cause analysis​
  • A valid back-end protocol was not specified in the Ingress Annotation.​
  • The gRPC service can be accessed only by using a TLS port.​
Solution​
  • In the corresponding Ingress, add nginx.ingress.kubernetes.io/backend-protocol:"GRPC" Annotation.​
  • Confirm that the client sends requests over the TLS port and that the traffic is encrypted.​
