Hi,

The nginx config sets the document root to /var/www/html however the volume is mounted at /usr/share/www/html. Delete the pod and set the nginx-container volume mount to /var/www/html. Then copy the index.php file and curl localhost:8099 from the nginx-container. You should be able to view the php you copied. Good luck

After that, do we need to write the YAML file for the pod and apply that???
