This is an AIO container done mostly right. It contains Nginx, PHP 8.3 and FPM preconfigured. It also comes with a watchdog that ensures that a failure will bring down the container, allowing for self-healing by recreating containers.
The support will ensure that composer is installed by checking for the presence of a *vendor* directory, and that the cache directories exist and are writable.
It will invoke the following hooks in the `/application/` directory if present:
-`.symfony-preinit` - invoked before the *vendor* directory check and any composer calls.
-`.symfony-init` - invoked after the *vendor* directory check.
