If you want to run PHP locally and leave docker for just external services (mysql, redis, elastic and rabbitmq):
- Make sure to have a local PHP installation. The minimum PHP version needed is 7.4.1.
- Needed PHP extensions: bcmath, pdo_mysql, pcntl, posix, mysqli.
- Make sure to install Symfony CLI.

Local Symfony Webserver + Docker for external services
