HTTPRoute를 배포합니다.

```
이 명령어는 app1이라는 HTTPRoute를 만들고 모든 RPC를 helloworld 서비스로 전송합니다.

parentRef 서비스도 helloworld 서비스이므로 HTTPRoute가 이 서비스에 연결되고 이 서비스에 전달된 모든 RPC를 처리합니다. 프록시리스 gRPC의 경우 대상 xds:///helloworld.default.svc.cluster.local:50051의 gRPC 채널에서 RPC를 전송하는 모든 클라이언트를 의미합니다.
새 app1 HTTPRoute가 생성되었는지 확인합니다.
```
kubectl get httproute
```
출력은 다음과 비슷합니다.
```
NAME   HOSTNAMES   AGE
app1               72s
```

클라이언트 설정

이 섹션에서는 gRPC 클라이언트를 사용하여 Cloud Service Mesh가 메시에서 트래픽을 올바르게 라우팅하는지 확인하는 방법을 설명합니다.

gRPC 클라이언트를 실행하고 HTTPRoute로 지정된 라우팅 구성을 사용하도록 지시합니다.

Google Cloud Managed Service for Prometheus 설정(선택사항)

Google Cloud Managed Service for Prometheus PodMonitoring 리소스를 배포하여 측정항목을 Cloud Monitoring으로 내보낼 수 있습니다.

서버의 경우 다음 명령어를 실행합니다.

kubectl apply -f - <<EOF

클라이언트의 경우 다음 명령어를 실행합니다.

PodMonitoring 리소스를 배포하면 일치하는 각 포드의 localhost:9464/metrics가 10초마다 스크래핑되고 그 결과를 Cloud Monitoring으로 내보냅니다.

Cloud Monitoring에서 측정항목을 보려면 다음 단계를 수행합니다.

Google Cloud 콘솔의 측정항목 탐색기 섹션으로 이동하고 Prometheus 대상 > Grpc를 선택하여 측정항목을 찾을 수 있습니다.

Cloud Service Mesh 관측 가능성 문제 해결

이 섹션에서는 일반적인 문제를 해결하는 방법을 설명합니다.

측정항목이 내보내지 않거나 표시되지 않음

관련된 모든 바이너리 (클라이언트 및 서버 모두)가 관측 가능성으로 설정되어 있는지 확인합니다.

Prometheus 내보내기 도구를 사용하는 경우 Prometheus 내보내기 도구의 URL이 예상대로 설정되어 있는지 확인합니다.

gRPC 채널에 Cloud Service Mesh가 사용 설정되어 있는지 확인합니다. 채널의 타겟은 xds:/// 형식이어야 합니다. gRPC 서버는 항상 Cloud Service Mesh에 사용 설정됩니다.

내보낸 측정항목 없음 / 측정항목의 속성 값이 알 수 없음으로 표시됨

Cloud Service Mesh 관측 가능성은 환경 라벨을 통해 메시 토폴로지 정보를 결정합니다. 클라이언트와 서비스 모두의 포드 또는 서비스 사양이 예시에 설명된 대로 모든 라벨을 지정하는지 확인합니다.

psm-grpc-server 배포를 설명합니다.

kubectl describe Deployment psm-grpc-server | grep "psm-grpc-server:" -A 12

출력은 다음과 비슷합니다.
