Configurer un maillage de services gRPC sans proxy sur GKE
Cette page explique comment déployer un exemple de client et de serveur gRPC sans proxy dans un maillage de services Cloud.
Prérequis
Pour commencer, nous partons du principe que vous avez déjà:
- créé un cluster GKE et l'avoir enregistré dans un parc ;
- Installer les définitions de ressources personnalisées
Conditions requises
Cette section liste les exigences concernant les services compatibles :
- gRPC C++ 1.62.0 ou version ultérieure
- Java gRPC : version 1.65.0 ou ultérieure
- Go gRPC : version 1.65.0 ou ultérieure
- gRPC Python 1.65.0 ou version ultérieure
Configurer le service
Déployez un service gRPC :
C++
kubectl apply -f - <<EOF

Configuration de Google Cloud Managed Service pour Prometheus (facultatif)
Vous pouvez déployer la ressource PodMonitoring Google Cloud Managed Service pour Prometheus pour exporter les métriques vers Cloud Monitoring.
Pour les serveurs, exécutez la commande suivante:
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 EOFPour les clients, exécutez la commande suivante :
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 EOFAprès avoir déployé la ressource
PodMonitoring, lelocalhost:9464/metricsde chaque pod correspondant sera extrait toutes les 10 secondes et les résultats seront exportés vers Cloud Monitoring.
Pour afficher les métriques dans Cloud Monitoring, procédez comme suit:
accédez à la section "Explorateur de métriques" Console Google Cloud, sélectionnez Prometheus Target > grpc pour trouver les métriques.
Accéder à l'explorateur de métriques
Vérifier la configuration du maillage de services gRPC sans proxy et l'observabilité du maillage
Vérifiez la sortie des métriques du pod client :
kubectl exec $(kubectl get po | grep psm-grpc-client | awk '{print $1;}') -- /usr/bin/curl -s http://localhost:9464/metricsLe résultat affiche les métriques (avec les étiquettes du maillage de services) qui ont été à partir du point de terminaison:

Résoudre les problèmes d'observabilité de Cloud Service Mesh
Cette section explique comment résoudre les problèmes courants.
Une valeur d'attribut de la métrique s'affiche comme inconnue
Si une valeur d'attribut de la métrique s'affiche comme inconnue, assurez-vous que tous les binaires impliqués (client et serveur) ont configuré un maillage de services gRPC sans proxy sur GKE.
Notez que l'observabilité Cloud Service Mesh détermine la topologie du maillage grâce aux étiquettes d'environnement. Assurez-vous que les spécifications du pod ou du service pour le client comme pour le service spécifient tous les libellés, comme décrit dans à titre d'exemple.

Les métriques ne s'affichent pas
Si vous utilisez l'exportateur Prometheus, vérifiez que l'URL de l'exportateur Prometheus est configurée comme prévu.
Assurez-vous que les canaux gRPC sont compatibles avec Cloud Service Mesh. Les canaux
doit avoir une cible au format xds:///. Les serveurs gRPC sont toujours activés pour
Cloud Service Mesh.
