How to allow SOCK_RAW generation for php-fpm?

Question

PHP

Kind!

I can not in any way allow the creation of SOCK_RAW for nginx + php-fpm in an LXC container.

There is a simple monitoring software ( www.phpservermonitor.org/) that can also monitor the availability of servers by icmp ping. To do this, at the time of the poll, SOCK_RAW is created in php.

But when creating a socket, php-fpm throws an error:

FastCGI sent in stderr: "PHP message: PHP Warning:  socket_create(): 
Unable to create socket [1]: Operation not permitted

How do I allow socket creation?

The error appears in nginx+php-fpm7 on Debian 9 and Alpine 3.7 in an LXC container.
