gRPC

This example demonstrates how to route traffic to a gRPC service through the Ingress-NGINX controller.

Prerequisites

  1. You have a kubernetes cluster running.
  2. You have a domain name such as example.com that is configured to route traffic to the Ingress-NGINX controller.
  3. You have the ingress-nginx-controller installed as per docs.
  4. You have a backend application running a gRPC server listening for TCP traffic. If you want, you can use https://github.com/grpc/grpc-go/blob/91e0aeb192456225adf27966d04ada4cf8599915/examples/features/reflection/server/main.go as an example.
  5. You're also responsible for provisioning an SSL certificate for the ingress. So you need to have a valid SSL certificate, deployed as a Kubernetes secret of type tls, in the same namespace as the gRPC application.

Step 1: Create a Kubernetes Deployment for gRPC app

  • Make sure your gRPC application pod is running and listening for connections. For example you can try a kubectl command like this below: 
    $ kubectl get po -A -o wide | grep go-grpc-greeter-server
-

  • If you have a gRPC app deployed in your cluster, then skip further notes in this Step 1, and continue from Step 2 below.

  • As an example gRPC application, we can use this app https://github.com/grpc/grpc-go/blob/91e0aeb192456225adf27966d04ada4cf8599915/examples/features/reflection/server/main.go.

  • To create a container image for this app, you can use this Dockerfile.

  • If you use the Dockerfile mentioned above, to create a image, then you can use the following example Kubernetes manifest to create a deployment resource that uses that image. If necessary edit this manifest to suit your needs.

cat <<EOF | kubectl apply -f -
