适用于Nginx和php-fpm的Docker

Question

I'm getting started with Docker and docker-compose

My first step was to build a stack with 2 containers : 1 for nginx and 1 for php-fpm

With that config, it's working

version: '3.3'
services:
    web:
        image: nginx
        ports:
            - "9090:80"
        volumes:
            - ./conf/default.conf:/etc/nginx/conf.d/default.conf:ro
            - ./content:/usr/share/nginx/html:ro
        links:
            - php
    php:
        image: php:7.1.8-fpm
        volumes:
            - ./content:/usr/share/nginx/html:ro

In /content I have both a index.html and phpinfo.php

I can get both pages in my browser.

But I don't understand why I have to put all my pages in both containers ?

If I don't put the volume for the php service , the index.html is displaying but not the phpinfo.php (File not found.)

If I don't put the volume for the web service , the nginx index.html is displaying but not the phpinfo.php (404 error).

So now if I want to deploy a wordpress site I will have to copy all the files in both containers ?

Bad configuration. Good practice is to separate all processes, so you should have 3 services: nginx, php-fpm and php. Source code should be ONLY inside php container.
