Docker + nginx + slim - docker

Question

I'm a new user of Docker. What I want to do is to setup (on my Windows PC) the Docker platform with a nginx server and a slim framework on this server, so that I be able to "host" a simple "hello world" page.
My question is: should I create a container containing the Nginx and inside that container install the Slim framework?
Or should i create two different containers (one for Nginx, one for Slim). And if so, how those two communicate?
Anyway whatever the solution is, first I would like to understand the "architecture" of this "build" and after that how to do it.
Thanks in advance

You can use two containers, using docker-compose to connect slim and nginx, something like this:
docker-compose.yaml
version: "3.8"
services:
php:
container_name: slim
build:
context: ./docker/php
ports:
- '9000:9000'
volumes:
- .:/var/www/slim_app
nginx:
container_name: nginx
image: nginx:stable-alpine
ports:
- '80:80'
volumes:
- .:/var/www/slim_app
- ./docker/nginx/default.conf:/etc/nginx/conf.d/default.conf
depends_on:
- php
DOCKERFILE in ./docker/php
FROM php:7.4-fpm
RUN docker-php-ext-install ALL_YOUR EXTENSIONS
WORKDIR /var/www/slim_app
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
Docker nginx in /docker/nginx/default.conf
server {
listen 80;
index index.php;
server_name localhost;
root /var/www/slim_app/public;
location / {
try_files $uri /index.php$is_args$args;
}
location ~ ^/index\\.php(/|$) {
fastcgi_pass php:9000;
fastcgi_split_path_info ^(.+\\.php)(/.*)$;
internal;
}
location ~ \\.php$ {
return 404;
}
}
Just execute the containers
docker-compose up -d
go to http://localhost/
