Why can't I run the application through docker?

Question

PHP

Hello! I'm trying to run a symfony application using docker. I downloaded the symfony application using composer'a api

composer create-project symfony/skeleton my_project_name

. Created in the installed project Dockerfile. Filled it with content like this

FROM php:7.4-cli

ADD . /opt/symfony
WORKDIR /opt/symfony

EXPOSE 8080

CMD ["php", "-S", "localhost:8080", "-t", "public/"]

That is, in fact, port 8080 opens and I php -S localhost:8080 -t public/start the server with the command.
Then I build this project sudo docker build -t name/symfony .
And run it sudo docker run -p 8080:8080 name/symfony
I get this:


And I try to go to localhost:8080 from the browser, but I get this


How can I fix this? Why can't I access the app?

Answer 1

And will you also run it in production on the server built into the php?
Since you are already using docker, use the php-fpm 7.4 application server, and nginx 1.19 as the web server. (Well, or try to reproduce the combination on which the application will work in production)
There will be fewer surprises later, because you will learn about them in the development process.
For docker-compose, the config will look something like this:

version: '2'
services:
    nginx:
        image: nginx:1.19
        ports:
              - "80:80"
        volumes:
            - ./path_to_nginx_config:/etc/nginx/conf.d
            - ./path_to_app:/var/www/app
        links:
            - php
    php:
        image: php:7.4-fpm
        ports:
            - "9000:9000"
        volumes:
            - ./path_to_app:/var/www/app
