<p>I created a single-node kubeadm cluster on bare-metal and after some research I would go for a host network approach (<a href="https://kubernetes.github.io/ingress-nginx/deploy/baremetal/#via-the-host-network" rel="noreferrer">https://kubernetes.github.io/ingress-nginx/deploy/baremetal/#via-the-host-network</a>), since NodePort is not an option due to network restrictions. </p>

<p>I tried installing nginx-ingress with helm chart through the command:</p>

<pre><code>   helm install stable/nginx-ingress \
     --set controller.hostNetwork=true
</code></pre>

<p>The problem is that it is creating a LoadBalancer service which is Pending forever and my ingress objects are not being routed:</p>

<p>Is there any other configuration that needs to be done to succeed in this approach?</p>

<p>@ijaz-ahmad-khan @vkr gave good ideas for solving the problem but the complete steps for setup are:</p>

<p>1) Install nginx-ingress with: </p>

<pre><code>helm install stable/nginx-ingress --set controller.hostNetwork=true,controller.service.type="",controller.kind=DaemonSet
</code></pre>

<p>2) In your deployments put:</p>

<pre><code>spec:
  template:
    spec:
      hostNetwork: true
</code></pre>

<p>3) In all your Ingress objects put:</p>

<pre><code>metadata:
  annotations:
    kubernetes.io/ingress.class: "nginx"  
</code></pre>
