<p>I try to install Traefik Web UI, but under Vagrant, without Minikube. This is a Multi-Node setup. On the host machine, I tried to reach UI both under <code>localhost:8081</code> (guest 8080 port exposed to host in Vagrantfile) and <code>https://localhost:6443/api/v1/namespaces/kube-system/services/https:traefik-web-ui:/proxy/</code> without luck. Can you recommend a working setting? On this last URL, I'm getting this error:</p>

<pre class="lang-json prettyprint-override"><code>{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {

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

<p>SSHing into the master machine, the Web UI is working:</p>

<pre class="lang-bash prettyprint-override"><code>vagrant@my-project-master:/vagrant$ kubectl get services --namespace=kube-system

<p>The current <code>ui.yml</code>:</p>

<pre class="lang-yaml prettyprint-override"><code>---

<p>Installed with:</p>

<pre class="lang-bash prettyprint-override"><code>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
</code></pre>

<p>How can I reach the Web UI on the host machine, preferably make it available for the host browser with only an installed certificate?</p>

<p>I use the Kubernetes Dashboard similarly, with the certificate installed on the host browser.</p>

Lanti
<p>I found the correct URL under the API to reach the UI:</p>

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

<p>Making these commands obsolute:</p>

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