I have installed the varnish on the server.
Now I want to configure it with Magento 2

When I run the following command to check if varnish is enabled or not, it doesn't show X-varnish in the response header. It seems that varnish is not configured with Magento 2 properly.
curl -I -v --location-trusted 'http://4.1.173.181/magento2'
Am I doing anything wrong?
Please help.
