Nginx Ingress Controller - 404 not found

General Discussions
1

Hi all, we’re new to Kubernetes we’re trying to build a nginx-php app, and with a persistent volume claim. We’re able to see the phpinfo from an initcontainer, however when tried accessing from our nginx ingress it’s giving a 404 not found. How can we edit the nginx config and add a running vhost? Thanks!

Here are the details for our configs:

      root /dir;

      location / {
          try_files $uri $uri/ /index.php?$query_string;
      }

      location ~ \.php$ {
          try_files $uri =404;
          fastcgi_split_path_info ^(.+\.php)(/.+)$;
          fastcgi_pass php:9000;
          fastcgi_index index.php;
          include fastcgi_params;
