gRPC Tests

This repo contains a gRPC application for testing with Envoy. The gRPC Server streaming endpoint sends one task into the stream per second to test timeout and keepAlive configurations.

Tests

• ✔ Unary RPC
• ✔️ Server-Streaming RPC
• ✔️ Stream Interceptor
• ✔️ Unary Interceptor

Gloo Edge

Deploy grpc-tests app

kubectl apply -f k8s/grpc-tests.yaml

Create a virtual service in Gloo Edge

kubectl apply -f k8s/vs-grpc-test.yaml

Apply access logging configuration to the gateway/gateway-proxy for logs (Optional)
(I am testing on AWS, if you are using GKE, set useProxyProto: false on line 35)

kubectl apply -f k8s/gateway-gateway-proxy.yaml

Enable Gloo Edge Function Discovery Service

kubectl label upstream -n gloo-system default-grpc-tests-8080 discovery.solo.io/function_discovery=enabled

kubectl get upstream -n gloo-system default-grpc-tests-8080 -o yaml

Enumerate the available grpc services

grpcurl -plaintext $(glooctl proxy address --port http) list

Describe gRPC Services

grpcurl -plaintext $(glooctl proxy address --port http) describe todo.Todo

Create a single task

grpcurl -plaintext -d '{"name":"Solo Test"}' $(glooctl proxy address --port http) todo.Todo/CreateTask

Create multiple tasks (Do this to test grpc server streaming endpoint)

GetTasks (Unary RPC)

grpcurl -plaintext $(glooctl proxy address --port http) todo.Todo/GetTasks

GetTasks (server streaming RPC)

grpcurl -plaintext  $(glooctl proxy address --port http) todo.Todo/GetTasksStream  

Get Access Logs

kubectl logs -f deploy/gateway-proxy -n gloo-system | grep '^{' | jq

Get app logs

kubectl logs -f deploy/grpc-tests
