Minikube / Grafana：連接被拒絕

Question

我正在嘗試使用 minikube 1.13.0 在 minikube 本地集群中minikube 1.13.0

這是整個過程：

minikube start # this step is OK

我使用以下命令部署 Grafana：

kubectl config use-context minikube
kubectl create namespace monitoring --dry-run=client -o yaml | kubectl apply -f -
kubectl create secret generic grafana-env --from-env-file=.env.local --namespace=monitoring --dry-run=client -o yaml | kubectl apply -f -
kubectl apply -f deployment/local/grafana-pvc.yml
kubectl apply -f deployment/local/grafana-secret.yml
kubectl apply -f deployment/local/grafana-deployment.yml
kubectl apply -f deployment/local/grafana-svc.yml
kubectl apply -f deployment/local/grafana-ingress-local.yml

服務 ：

apiVersion: v1
kind: Service
metadata:
  name: grafana-local
  namespace: monitoring
  labels:
    app: grafana-local
    component: core
spec:
  type: NodePort
  ports:
    - port: 3000
  selector:
    app: grafana-local
    component: core

和入口：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: grafana-ingress
  namespace: monitoring
  annotations:
    kubernetes.io/ingress.class: traefik
spec:
  rules:
  - host: grafana.local
    http:
      paths:
      - backend:
         serviceName: grafana-local
         servicePort: 3000

我還在/etc/hosts添加了一個 grafana.local 條目以將其鏈接到127.0.0.1

Pod、service、ingress都部署成功了，沒看到錯誤。

但是當我嘗試通過 chrome 訪問它時，我收到一個ERR_CONNECTION_REFUSED錯誤。

重要的是要說之前，我使用 none 驅動程序啟動 minikube，並且運行良好：

sudo minikube start --vm-driver none

另外，當我這樣做時：

minikube dashboard

我可以毫無問題地訪問儀表板。

我缺少什么？

Answer 1

只需在單獨的終端中運行kubectl port-forward ：

kubectl -n monitoring port-forward svc/grafana-local 3000

然后你就可以在http://127.0.0.1:3000上訪問 Grafana。
