I tried a lot of combinations of configurations of php.ini file, config/logging.php, LOG_CHANNEL of .env, many options of stack configuration and much more.

I am using the PHP version 7.4.28. laravel/framework v7.11.0 Composer version 2.2.6

The project was cloned from Github: https://github.com/do-community/travellist-laravel-demo

All the containers are up and running:

How can i get the logs from Laravel in the stdout of my Docker Container?

Answer 1

Editing.

For anyone having a similar problem, when trying to get Laravel logs from Container stdout. In my case, I use the container with Laravel in a Kubernetes Pod, so I added the third step I needed to do.

Solution:

1 - Create logging.php file and set the stack with the single channel.

[... rest of the code omitted, for short...]

'channels' => [
    'stack' => [
        'driver' => 'stack',
        'channels' => ['single'],
        'ignore_exceptions' => false,
    ],

    'single' => [
        'driver' => 'single',
        'path' => storage_path('logs/laravel.log'),
        'level' => 'debug',
        'permission' => 0660,

[... rest of the code omitted, for short...]

2 - Configure the LOG_CHANNEL environment variable with the stack value:

LOG_CHANNEL=stack

3 - Use the Lifecycle that does the tail in the log file:
