Question

我尝试安装Traefik Web UI，但是在Vagrant下，没有Minikube。这是一个多节点设置。在主机上，我尝试在localhost:8081（Vagrantfile中公开给主机的guest 8080端口）和https://localhost:6443/api/v1/namespaces/kube-system/services/https:traefik-web-ui:/proxy/下都没有运气的情况下访问UI。你能推荐一个工作环境吗？在此最后一个URL上，出现此错误：

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {

  },
  "status": "Failure",
  "message": "no endpoints available for service \"https:traefik-web-ui:\"",
  "reason": "ServiceUnavailable",
  "code": 503
}

通过SSH进入主计算机，Web UI正在工作：

vagrant@my-project-master:/vagrant$ kubectl get services --namespace=kube-system
NAME                      TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)           AGE
...
traefik-ingress-service   ClusterIP   10.110.210.58    <none>        80/TCP,8080/TCP   4m30s
traefik-web-ui            ClusterIP   10.98.235.112    <none>        80/TCP            4m29s

vagrant@my-project-master:/vagrant$ curl 10.110.210.58:8080/dashboard/

当前的ui.yml：

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

已安装：

kubectl apply -f https://raw.githubusercontent.com/containous/traefik/master/examples/k8s/traefik-rbac.yaml
kubectl apply -f https://raw.githubusercontent.com/containous/traefik/master/examples/k8s/traefik-ds.yaml
#kubectl apply -f https://raw.githubusercontent.com/containous/traefik/master/examples/k8s/ui.yaml
kubectl apply -f /vagrant/hashicorp/manifests/traefik/ui.yml

如何才能在主机上访问Web UI，最好仅通过已安装的证书将其提供给主机浏览器使用？

我类似地使用Kubernetes仪表板，并将证书安装在主机浏览器上。

我在API下找到了正确的URL即可到达用户界面：

https://localhost:6443/api/v1/namespaces/kube-system/services/http:traefik-ingress-service:8080/proxy/dashboard/

绝对使这些命令：

kubectl apply -f https://raw.githubusercontent.com/containous/traefik/master/examples/k8s/ui.yaml
# or
kubectl apply -f /vagrant/hashicorp/manifests/traefik/ui.yml

在Vagrant下使用Kubernetes公开用于主机的Traefik Web UI
