I'm trying to create pods there Kubernetes, all are successfully created, but an application is not visible to nginx. nginx is only viewing the default html file and not the project file.

Nginx.yaml configuration file, where I create configuration, service, and deployment

apiVersion: v1
kind: ConfigMap
metadata:
  name: nginx-conf
data:
  nginx.conf: |

    server {
        listen 80;
        index index.php index.html;
        root /usr/share/nginx/html;

        location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass app-service:9000;
            fastcgi_index index.php;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param PATH_INFO $fastcgi_path_info;
        }

        location / {
            try_files $uri $uri/ /index.php$query_string$args;
            gzip_static on;
        }
    }

In the app.yaml file, I download an image of docker, configuration or database access, and configuration creation, service, and deployment.
