Phalcon with docker, php-fpm.sock not created in container

Hello,

I create one container with (Ubuntu 14.04 + nginx + php5-fpm + Phalcon).
In my .conf I configured with “fastcgi_pass php:9000;” because I dont find “php-fpm.sock” in container.

Anybody knows why dont create the “php-fpm.sock” ?

Sry for my english, tnks.
