Docker containers for Symfony 3.4

This repository provides standard containers for Symfony 3.4.

Containers are:

• webserver-tech: Nginx
• app-tech: Php
• db-tech: MySql

Clone the repo and run

docker-compose build

And then:

docker-compose up -d

You should be able to access the site at http://localhost:90

Common problems

• If you have already MySql running on the port 3306, change the port in the docker-compose.yml file

• Same with the port 80 (or 90): if Apache or any other webservers are running on the port 80 (or 90), change the port in the docker-compose.yml file

• If you see the error 404, you should check the index path in environment/nginx/conf.d

• For the error 500, open the localhost:90/app_dev.php file and you should be able to see the problem (or open the logs)

• If you receive an error like:

  An exception occured in driver: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known  

most probably you have a problem in the database configuration in symfony/app/config/parameters.yml. Run:

docker inspect db-tech

to find out the gateway IP address of the container. Also, double check the database credentials.

• If you receive the error "You are not allowed to access this file. Check app_dev.php for more information.", inspect your app-tech container and find the gateway IP Address:

docker inspect app-tech

check your /symfony/web/app_dev.php and modify it with the IP address you found:

if (isset($_SERVER['HTTP_CLIENT_IP'])
    || isset($_SERVER['HTTP_X_FORWARDED_FOR'])
    || !(in_array(@$_SERVER['REMOTE_ADDR'], ['127.0.0.1', 'fe80::1', '::1', '172.20.0.1']) || php_sapi_name() === 'cli-server')
) {
    header('HTTP/1.0 403 Forbidden');
    exit('You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
}
