Traefik 仪表板拒绝使用 minikube 连接

Question

我尝试使用 helm 将 Traefik (v1.7) 部署到本地 minikube 集群

helm install --values values.yml stable/traefik

values.yml：

dashboard:
  enabled: true
  domain: dashboard.localhost
kubernetes:
  namespaces:
    - default
    - kube-system

我在 /etc/hosts 文件中添加了 dashboard.localhost 但我无法访问仪表板。

curl http://dashboard.localhost:31745/
404 page not found

curl http://dashboard.localhost/ 

没有回应...

在浏览器中：

有科动物吗？

更新：

A 根据 Traefik 文档创建并应用了两个服务。 我的变种：

apiVersion: v1
kind: Service
metadata:
  name: traefik-web-ui
  namespace: default
spec:
  selector:
    app: traefik
  ports:
  - name: web
    port: 80
    targetPort: 8080
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: traefik-web-ui
  namespace: default
spec:
  rules:
  - host: dashboard.localhost
    http:
      paths:
      - path: /
        backend:
          serviceName: traefik-web-ui
          servicePort: web

Traefic 1.7 文档变体：

apiVersion: v1
kind: Service
metadata:
  name: traefik-web-ui
  namespace: kube-system
spec:
  selector:
    k8s-app: traefik-ingress-lb
  ports:
  - port: 80
    targetPort: 8080
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: traefik-web-ui
  namespace: kube-system
  annotations:
    kubernetes.io/ingress.class: traefik
spec:
  rules:
  - host: traefik-ui.minikube
    http:
      paths:
      - backend:
          serviceName: traefik-web-ui
          servicePort: 80

我的 /etc/hosts

127.0.0.1   localhost
255.255.255.255 broadcasthost
::1             localhost
127.0.0.1   test
192.168.99.111  dashboard.localhost
192.168.99.111 traefik-ui.minikube

打开http://traefik-ui.minikube 最终结果是 ERR_CONNECTION_TIMED_OUT...

要访问仪表板，您必须创建两个服务，如 traefik docs 中所述：

apiVersion: v1
kind: Service
metadata:
  name: traefik-web-ui
  namespace: kube-system
spec:
  selector:
    k8s-app: traefik-ingress-lb
  ports:
  - port: 80
    targetPort: 8080
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: traefik-web-ui
  namespace: kube-system
  annotations:
    kubernetes.io/ingress.class: traefik
spec:
  rules:
  - host: traefik-ui.minikube
    http:
      paths:
      - backend:
          serviceName: traefik-web-ui
          servicePort: 80

然后在etc/hosts:中添加一个条目

echo "$(minikube ip) traefik-ui.minikube" | sudo tee -a /etc/hosts
