Configura una malla de servicios de gRPC sin proxy en GKE
En estas páginas, se describe cómo implementar un ejemplo de cliente y servidor de gRPC sin proxy en una malla de servicios de Cloud.
Requisitos previos
Como punto de partida, en esta guía se supone que ya hiciste lo siguiente:
- Creaste un clúster de GKE y lo registraste en una flota.
- Instalaste las definiciones de recursos personalizados.
Requisitos
En esta sección, se enumeran los requisitos para los servicios compatibles:
- gRPC C++, versión 1.62.0 o posterior
- gRPC Java: versión 1.65.0 o posterior
- gRPC Go: versión 1.65.0 o posterior
- gRPC Python: versión 1.65.0 o posterior
Configura el Service
Implementa un servicio de gRPC:

también eshelloworld
, lo que significa que nuestro HTTPRoute se adjunta a este servicio y procesará todas las RPC dirigidas a este servicio. En el caso de gRPC sin proxy, significa cualquier cliente que envíe RPC en un canal de gRPC para elxds:///helloworld.default.svc.cluster.local:50051

kubectl get httproute
La salida es similar a lo siguiente:

Configura el cliente
En esta sección, se describe cómo usar un cliente gRPC para verificar que Cloud Service Mesh enrute el tráfico correctamente en la malla.
Ejecutar un cliente de gRPC y indicarle que use la configuración de enrutamiento especificada por la HTTPRoute:

Configuración de Google Cloud Managed Service para Prometheus (opcional)
Puedes implementar Google Cloud Managed Service para Prometheus
Recurso PodMonitoring
para exportar las métricas a Cloud Monitoring.
Para los servidores, ejecuta el siguiente comando:
kubectl apply -f - <<EOF apiVersion: monitoring.googleapis.com/v1 kind: PodMonitoring metadata: name: psm-grpc-server-gmp spec: selector: matchLabels: app: psm-grpc-server endpoints: - port: 9464 interval: 10s EOF
Para los clientes, ejecuta el siguiente comando:
kubectl apply -f - <<EOF apiVersion: monitoring.googleapis.com/v1 kind: PodMonitoring metadata: name: psm-grpc-client-gmp spec: selector: matchLabels: app: psm-grpc-client endpoints: - port: 9464 interval: 10s EOF
Después de implementar el recurso
PodMonitoring
, cada Pod que coincida Se copiarálocalhost:9464/metrics
cada 10 segundos y exportará la los resultados a Cloud Monitoring.
Para ver las métricas en Cloud Monitoring, sigue estos pasos:
Puedes navegar a la sección Explorador de métricas de la consola de Google Cloud, seleccionar Prometheus Target > Grpc para encontrar las métricas.
Verifica la configuración de la malla de servicios de gRPC sin proxy y la observabilidad de la malla
Verifica el resultado de las métricas del Pod cliente:
kubectl exec $(kubectl get po | grep psm-grpc-client | awk '{print $1;}') -- /usr/bin/curl -s http://localhost:9464/metrics
El resultado muestra las métricas (con las etiquetas de la malla de servicios) que se recuperaron del extremo:

Soluciona problemas de observabilidad de Cloud Service Mesh
En esta sección, se muestra cómo solucionar problemas habituales.
Un valor de atributo en la métrica se muestra como desconocido.
Si un valor de atributo en la métrica aparece como desconocido, asegúrate de que todos los objetos binarios involucrados (cliente y servidor) tengan configurada una malla de servicios de gRPC sin proxy en GKE.
Ten en cuenta que la observabilidad de la malla de servicios de Cloud determina la topología de la malla información mediante etiquetas de entorno. Asegúrate de que la especificación del pod o servicio del cliente y del servicio especifique todas las etiquetas como se describe en el ejemplo.
Describe la implementación de psm-grpc-server:
kubectl describe Deployment psm-grpc-server | grep "psm-grpc-server:" -A 12

No se muestran las métricas
Si usas el exportador de Prometheus, verifica que la URL del exportador de Prometheus esté configurada según lo esperado.
Asegúrate de que los canales de gRPC tengan habilitado Cloud Service Mesh. Los canales deben tener un objetivo con el formato xds:///
. Los servidores gRPC siempre están habilitados
la malla de servicios en la nube.
