<p>I have this ingress and service created on my Kubernetes cluster</p>
<pre class="lang-yaml prettyprint-override"><code>apiVersion: v1

    nginx.ingress.kubernetes.io/backend-protocol: &quot;HTTPS&quot;

        backend:
          serviceName: google-storage-buckets
          servicePort: 443
</code></pre>
<p>However, this works only if I add <code>index.html</code> after gatsby.vegeta.kintohub.net.</p>
<p>Same if I go on gatsby.vegeta.kintohub.net/page-2.</p>
<p>How could I make this work plz?</p>
<p>Thanks</p>

<p>We had a very similar case, gatsby static site on a GCP bucket.</p>
<p>we also tested <code>try_files</code> and <code>index</code> directives but didn't work.</p>
<p>In our case these hacky <code>configuration-snippets</code> did the trick:</p>

<p>Everything seems to be working fine on our case, except for the 404s</p>
<p>There might be a more efficient way to do this but hopes this helps.</p>
