Configurar uma malha de serviço gRPC sem proxy no GKE
Esta página descreve como implantar um exemplo de servidor e cliente gRPC sem proxy em um do Cloud Service Mesh.
Pré-requisitos
Para começar, este guia pressupõe que você já:
- criou um cluster do GKE e o registrou em uma frota;
- Instalar as definições de recursos personalizados.
Requisitos
Esta seção lista os requisitos para os serviços compatíveis:
- gRPC em C++, versão 1.62.0 ou posterior
- gRPC em Java: versão 1.65.0 ou mais recente
- gRPC em Go: versão 1.65.0 ou mais recente
- gRPC Python: versão 1.65.0 ou mais recente
Configurar o serviço
Implante um serviço gRPC:
C++

Configuração do Google Cloud Managed Service para Prometheus (opcional)
É possível implantar o recurso PodMonitoring
do Google Cloud Managed Service para Prometheus para exportar as métricas para o Cloud Monitoring.
Para servidores, execute o seguinte 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 clientes, execute o seguinte 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
Depois de implantar o recurso
PodMonitoring
, olocalhost:9464/metrics
de cada pod correspondente será raspado a cada 10 segundos e exportará os resultados para o Cloud Monitoring.
Para conferir as métricas no Cloud Monitoring, siga estas etapas:
navegue até a seção Metrics Explorer do console do Google Cloud, selecione Prometheus Target > Grpc para encontrar as métricas.
Verificar a configuração da malha de serviço gRPC sem proxy e a Observabilidade da malha
Verifique a saída de métricas do pod do cliente:
kubectl exec $(kubectl get po | grep psm-grpc-client | awk '{print $1;}') -- /usr/bin/curl -s http://localhost:9464/metrics
A saída mostra as métricas (com os rótulos da malha de serviço) que foram extraídos do endpoint:

Resolver problemas de observabilidade do Cloud Service Mesh
Esta seção mostra como resolver problemas comuns.
Um valor de atributo na métrica aparece como desconhecido
Se um valor de atributo na métrica aparecer como desconhecido, verifique se todos binários envolvidos (cliente e servidor) são configurou uma malha de serviço gRPC sem proxy no GKE.
A Observabilidade do Cloud Service Mesh determina as informações topológicas da malha usando rótulos de ambiente. Verifique se a especificação do pod ou do serviço para o cliente e o serviço especifica todos os rótulos, conforme descrito no exemplo.
Descreva a implantação do psm-grpc-server:
kubectl describe Deployment psm-grpc-server | grep "psm-grpc-server:" -A 12
A saída é semelhante a:
psm-grpc-server: Image: grpc/csm-example-server:2024-02-13 Port: 50051/TCP Host Port: 0/TCP Args: --port=50051 Environment: GRPC_XDS_BOOTSTRAP: /tmp/grpc-xds/td-grpc-bootstrap.json POD_NAME: (v1:metadata.name) NAMESPACE_NAME: (v1:metadata.namespace) CSM_WORKLOAD_NAME: psm-grpc-server OTEL_RESOURCE_ATTRIBUTES: k8s.pod.name=$(POD_NAME),k8s.namespace.name=$(NAMESPACE_NAME),k8s.container.name=$(CONTAINER_NAME)
Descreva a implantação de psm-grpc-client:
kubectl describe Deployment psm-grpc-client | grep "psm-grpc-client:" -A 12
A saída é semelhante a:
psm-grpc-client: Image: grpc/csm-example-client:2024-02-13 Port: <none> Host Port: <none> Args: --target=xds:///helloworld.default.svc.cluster.local:50051 Environment: GRPC_XDS_BOOTSTRAP: /tmp/grpc-xds/td-grpc-bootstrap.json CSM_WORKLOAD_NAME: test-workload-name POD_NAME: (v1:metadata.name) NAMESPACE_NAME: (v1:metadata.namespace) CONTAINER_NAME: psm-grpc-client
As métricas não são exibidas
Se você estiver usando o exportador do Prometheus, verifique se o URL do Prometheus o exportador está configurado como esperado.
Verifique se os canais gRPC estão ativados no Cloud Service Mesh. Os canais
precisam ter um destino do formato xds:///
. Os servidores gRPC estão sempre ativados para
do Cloud Service Mesh.
