如何通过kubectl代理访问此Kubernetes服务？

我想通过kubectl代理服务器访问我的Grafana Kubernetes服务,但由于某种原因,即使我可以使其适用于其他服务,它也无法工作.鉴于以下服务定义,为什么它不能在http:// localhost:8001/api/v1/proxy/namespaces/monitoring/services/grafana上找到？

grafana-service.yaml

apiVersion: v1
kind: Service
metadata:
  namespace: monitoring
  name: grafana
  labels:
    app: grafana
spec:
  type: NodePort
  ports:
  - name: web
    port: 3000
    protocol: TCP
    nodePort: 30902
  selector:
    app: grafana

grafana-deployment.yaml

          valueFrom:

        emptyDir: {}
      - name: grafana-dashboards
        configMap:
          name: grafana-dashboards

我在访问上述URL时看到的错误是"没有端点可用于服务"grafana"",错误代码503.

正如迈克尔所说,很可能你的标签或命名空间不匹配.但是除此之外,请记住,即使您修复了端点,您所访问的URL(http:// localhost:8001/api/v1/proxy/namespaces/monitoring/services/grafana)也可能无法正常工作.

根据您的root_url和/或static_root_path grafana配置设置,当您尝试登录时,您可能会尝试将POST发送到http:// localhost:8001/login并获得404.

尝试使用kubectl port-forward代替:

kubectl -n monitoring port-forward [grafana-pod-name] 3000

然后通过http:// localhost:3000 /访问grafana

问题是Grafana的端口名为web，因此需要将其附加:web到kubectl代理URL：http：// localhost：8001 / api / v1 / proxy / namespaces / monitoring / services / grafana：web。

另一种选择是，不命名Grafana端口，因为这样您就不必:web在服务的kubectl代理URL后面附加：http：// localhost：8001 / api / v1 / proxy / namespaces / monitoring / services / grafana：web。最后我选择了这个选项，因为它更容易。

我不知道为什么，但是我无法在AKS上使用此模式。相反，我必须遵循此模式（末尾使用代理）：http：// localhost：8001 / api / v1 / namespaces / / services / ： / proxy /
