Question

我先部署traefik ingress controller吊舱，然后再部署两项服务，其中一项是用于反向代理的LoadBalancer类型，另一项是用于仪表板的ClusterIP类型。

我还创建了将所有<elb-address>/dashboard重定向到我的traefik仪表板的入口。

但是由于某些原因，当我尝试在aws-ip/dashboard上请求仪表板时收到404错误代码

那是我用来设置traefik的清单Yamls

更新

我正在查看日志，并在激活rbac并创建ClusterRole，ServiceRole和ServiceAccount的情况下收到以下错误：

Answer 1

我自己尝试过。因此，基本上，当您创建Ingress时，它是使用host（默认值）的traefik-ui.minikube创建的，因此您将无法使用<elb-address>/dashboard/访问仪表板。

您将必须使用traefik-ui.minikube/dashboard/访问它。例如：

$ kubectl -n kube-system get ingress
NAME              HOSTS                 ADDRESS                  PORTS   AGE
traefik-ingress   *                                                                                              80      8m13s
traefik-web-ui    traefik-ui.minikube   xxxx.elb.amazonaws.com   80      71d

$ curl -H 'Host: traefik-ui.minikube' xxxx.elb.amazonaws.com/dashboard/
<!doctype html><html class="has-navbar-fixed-top">
...
</html>

如果您想在浏览器中查看，也可以将条目添加到/etc/hosts文件中。

 <one-of-the-ips-of-your-elb> traefik-ui.minikube

您还可以在Ingress定义中使用host至rules：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  namespace: kube-system
  name: traefik-ingress
  annotations:
    kubernetes.io/ingress.class: traefik
spec:
  rules:
  - host: yourown.hostname.com
    http:
      paths:
      - path: /dashboard
        backend:
          serviceName: traefik-web-ui
          servicePort: web

Answer 2

解决方案

我应用

kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'

，然后安装带有头盔的稳定/ traefik模板

helm install stable/traefik --name=traefik-ingress-controller --values values.yaml

values.yaml文件是：仪表板：已启用：true 域：traefik-ui.k8s.io rbac：已启用：true kubernetes：命名空间： -默认 -kube系统

Traefik-ingress仪表板返回404
