<p>I have a use case that I need to expose</p>
<p>/swagger-ui.html without authentication and</p>
<p>/apis/* with authentication</p>
<p>I created 2 ingress files in helm chart</p>

<p>But seems like the second ingress does not work.</p>
<p>================================================================</p>
<p>Sagar Velankar's answer is correct. Just need to change different service name</p>
<p>Below is my final ingress file</p>

John
<p>Please try changing the Ingress name for both templates to be unique. Currently I see both are set to below</p>
<pre><code>name: {{ .Chart.Name }}

<p>I just changed apiVersion from extensions/v1beta1 to networking.k8s.io/v1beta1 and added below yaml files to my kubernetes cluster</p>
