php-fpm & nginx in separated docker container, can not execute .php file

Question

I'd like to setup an completely LNMP environment with docker on a machine. But there is something wrong with separated php-fpm & nginx container.

What I'v done is :

pull images from docker.io :

docker pull php:7.1-fpm

docker pull nginx
run with image :

docker run -d --name php-fpm -v /data/Docker/php-fpm/configs/:/usr/local/etc/php-fpm.d -v /data/Docker/nginx/html:/var/www/html php:7.1-fpm

docker run -d --name nginx -v /data/Docker/nginx/configs/:/etc/nginx -v /data/Docker/nginx/html:/var/www/html -p 80:80 --link php-fpm nginx

All directories & files are 755 privileges.

Config files r below :

nginx.conf

server {
    listen  80  default_server;
    server_name SkyEyeLab;
    root    /var/www/html;

    fastcgi_read_timeout 90;
    location ~ \.php {
    fastcgi_pass    php-fpm:9000;
    }
}

And php-fpm.conf(some of important config sections):

listen 0.0.0.0:9000
listen.allowed_clients = any

Then I checked the environment of nginx & php-fpm :

[root@w-Lab01 ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                         NAMES

Everything seems fine. Then I create a.php under /data/Docker/nginx/html(which is mouted to nginx's /var/www/html directory) with following content :

<?php
phpinfo();
?>

Then access http://localhost:80/a.php in web browser. But I only got an empty page, I checked the access.log of nginx :

[root@w-Lab01 ~]# docker logs 6faf4a4b4f7e
220.181.171.120 - - [11/Oct/2016:10:25:11 +0000] "GET /a.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0"

It seems a.php is correctly parsed & executed. But why I can not see phpinfo() result in web browser ?

well, after I changed nginx's config file :

server {
    listen  80  default_server;
    server_name SkyEyeLab;
    root    /var/www/html;

    fastcgi_read_timeout 90;
    location ~ \.php {
    fastcgi_pass    php-fpm:9000;
    }
}

to

server {
    listen  80  default_server;
    server_name SkyEyeLab;
    root    /var/www/html;

    fastcgi_read_timeout 90;
    location ~ \.php {
    fastcgi_pass    php-fpm:9000;
    include fastcgi.conf;
    }
}

erverything goes fine.

fastcgi.conf is environment config file. you can check under your nginx's config directory(usually /etc/nginx), and see if there is fastcgi.conf or fastcgi_param in it.
