私は実習でkubernetesを初めて体験しようとしています。rpi kubernetesノードのTraefikが返す404ページが見つかりません

kubernetes v1.9はクラスタとしてマウントされた5つのラズベリーパイに設定されています。

OS:hypriot V1.4

ホスト/静的IP構成/ラズベリーハードウェアバージョン:

  • マスタ:192.168.1.230/RPI V3
  • node01:192.168.1.231/RPI v3の
  • とnode02:192.168.1.232/RPI V3
  • node03の:192.168.1.233/RPI v2の
  • ノード04:192.168.1.234/rpi v2

私はウィーブネットを選択します。 Traefikはロードバランサとしてノード01にインストールされ、外部から私のサービスにアクセスします。 私は(原産地:https://blog.hypriot.com/post/setup-kubernetes-raspberry-pi-cluster/):マスターをsshとそれをインストールするには、これらのコマンドを使用し

$すべてのシステムポッドhttps://raw.githubusercontent.com/hypriot/rpi-traefik/master/traefik-k8s-example.yaml

$ kubectlラベルノードnode01 nginxのコントローラ= traefik

私はこのURL http://192.168.1.231/を使用してnode01に接続しようとすると問題があります。私が見つからない404ページを持って...

は、だから私は、ログをチェックして、彼らはデフォルトのアカウントに問題があることを把握:

実際にアカウントシステムに問題がありますか?serviceaccount:kube-system:defaultが使用されていますか?私の代わりにどんなアカウントを使うべきですか?

ありがとうございます。
