Hi,

I have a simple app with PHP 8.3/Laravel/Octane which I want to put in container. I use Laravel sample logging config 'single':

        'single' => [
            'driver' => 'single',
            'path' => 'php://stdout',
            'level' => env('LOG_LEVEL', 'debug'),
            'replace_placeholders' => true,
        ],

Starting this app (without container) with:
php artisan octane:frankenphp --log-level=debug
produces caddy access log, but no application logging is shown.
If I set path to 'php://stderr' - it works as expected. Of course it works as well if I log to a file.

Is there some configuration I am missing to emit application log on stdout to caddy/frankephp logger?

When logging to stdout, don't you have to use a configuration like this?

'stdout' => [
    'driver' => 'monolog',
    'level' => env('LOG_LEVEL', 'debug'),
    'handler' => StreamHandler::class,
    'formatter' => env('LOG_STDERR_FORMATTER'),
    'with' => [
        'stream' => 'php://stdout',
    ],
    'processors' => [PsrLogMessageProcessor::class],
],

It's because laravel octane runs frankenphp as a sub process and then forwards the output.

I just run it directly with a custom caddyfile. Much less hassle.

# in the dockerimage.
CMD ["frankenphp", "run", "-c", "/etc/caddy/Caddyfile"]

And a custom bootstrap stub in public/frankenphp-worker.php

<?php

// These env vars are required for the octane bootstrap file to work.
$_SERVER['MAX_REQUESTS'] = $_SERVER['LARAVEL_OCTANE_MAX_WORKER_REQUESTS'];
$_SERVER['REQUEST_MAX_EXECUTION_TIME'] = $_SERVER['LARAVEL_OCTANE_MAX_EXECUTION_TIME'];
$_SERVER['APP_BASE_PATH'] = dirname(__DIR__);
$_SERVER['APP_PUBLIC_PATH'] = $_SERVER['APP_BASE_PATH'].'/public';

require dirname(__DIR__).'/vendor/laravel/octane/bin/frankenphp-worker.php';

Had the same issue a while ago, logging to stderr instead of stdout solved the issue for us. As log levels are set explicitly anyhow, this does not affect logging services.
