Hello everybody,
i need some help and I hope that some of you can help me.
I downloaded all needed docker tools and setup some VM’s for following problem:
I want to create a LEMP Stack in Docker Container in a Docker swarm. I have 3 VM’s which are used as 3 nodes in the swarm. That is already working.
My problem is to distribute the mysql+nginx+php.
The nginx is running but PHP doesn’t work. I only could download the php file when i try to open the URL in the browser.
I use docker stack to deploy the containers about a docker-compose.yml file in the swarm. I don’t know what I’m doing wrong and I hope, that some of you could help me. The config files and the docker-compose.yml will follow.
Thank you a lot and sorry if something is wrong, it is my first post in this forum 
My docker-compose.yml file looks following:
version: '3'
services:
nginx:
image: nginx
ports:
- "8080:80"
volumes:
- ./code:/usr/share/nginx/html
- ./site.conf:/etc/nginx/default.conf
#- ./code:/var/www/html # I tried it with and without - no difference
php:
volumes:
- ./code:/usr/share/nginx/html
- ./php-fpm.conf:/etc/php/7.0/fpm/php-fpm.conf
working_dir: /usr/share/nginx/html
image: php:7-fpm
environment:
MYSQL_PASSWORD: Passw0rd
mysql:
image: mysql:5.7
volumes:
- mysql-data:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: Passw0rd
command: ['mysqld', '--character-set-server=utf8']
volumes:
mysql-data:
I also have following config file for my nginx:
site.conf
server {
listen 80;
root /usr/share/nginx/html;
index index.html index.htm index.php
location / {
try_files $uri =404;
}
location ~ \.php$ {
fastcgi_pass test-php:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
and this php-fpm.conf:
listen 0.0.0.0:9000
listen.allowed_clients = any
