<p>I use <a href="https://github.com/kubernetes/ingress-nginx/releases/tag/nginx-0.24.1" rel="noreferrer">nginx-ingress-controller:0.24.1</a> (<a href="https://github.com/kubernetes/ingress-nginx/issues/1809" rel="noreferrer">Inspired by</a>)</p>

<p>I would like to set a DNS A record to LB IP address, so it would connect it to the Google cloud public bucket (<code>my-back-end-bucket</code>) that has public index.html in the root AND to the back-end by another url rule.</p>

<p>By reaching <a href="https://my.ip.add.ress/c" rel="noreferrer">https://my.ip.add.ress/c</a> - got both outputs: <strong>Hello, world! bucket content.</strong></p>

<p><strong>"Hello, world!"</strong> form the <strong>hello-world-service</strong></p>

<p><strong>"bucket content"</strong> from the <strong>bucket</strong>' index.html file</p>

<p>Question: how to make it work so, that by <strong>ip/</strong> - I got a bucket content
and by <strong>ip/c</strong> - back-end response content ?</p>

ses
<p>You can split your ingress into two where one defines <code>path: /*</code> with necessary annotation and another ingress that defines <code>path: /c/</code>.</p>

<p>The problem with your single ingress is that its annotations that you want to apply to <code>path: /*</code> only gets applied to other paths as well.</p>
