<p>I need to remove a part path in a request uri. I'm using an ingress on Goocle Cloud to access to the server and I want that if I go to localhost/symfony/ the symfony path is ignored in the uri request. </p>

<p>At moment It works if I go to localhost/symfony but If I go to localhost/symfony/something I receive 404 default backend. 
I have tried also to add $1 to set request_url but it not works.</p>

<p>This is my configuration:  </p>

<p>Any suggestion? </p>

<p>You need to use annotations in the Ingress object to rewrite URI. The <code>nginx.ingress.kubernetes.io/rewrite-target</code> annotation targets URI where the traffic must be redirected. Example:</p>

<pre><code>    apiVersion: extensions/v1beta1
    kind: Ingress
    metadata:
      annotations:
        nginx.ingress.kubernetes.io/rewrite-target: /
      name: symfony-nginx-ingress
    spec:
      rules:
      - http:
          paths:
          - path: /symfony
            backend:
              serviceName: symfony-nginx-np
              servicePort: 80
</code></pre>

<p>In this case, it will rewrite URI from <code>localhost/symfony/</code> to <code>localhost/</code>.</p>

<p>Please note that it works for all endpoints described in the Ingress object.</p>
