Override config item in artisan kernel

[sinnbeck]

• Laravel Version: 5.7.28
• PHP Version: 7.2
• Database Driver & Version:

Description:

In 5.7.22 it was possible to override config items by overriding the bootstap method

public function bootstrap()
    {
        parent::bootstrap();
        if (App::environment('local')) {
            app('config')->set(['database.connections.mysql.host' => '127.0.0.1']);
        }
    }

This worked and used the new host when running database tasks
After upgrading to 5.7.28 this is no longer possible

Steps To Reproduce:

Install 5.7.22 and check that it is possible to override database host.
Install 5.7.28 and see that it no longer works.

Can you pinpoint the exact version which broke this? That might give a hint what's causing this.

Works in 5.7.24 and breaks in 5.7.25

[driesvints]

I can't really see what might have caused this honestly: v5.7.24...v5.7.25

It seems to be this
src/Illuminate/Database/DetectsLostConnections.php
Here you removed
'php_network_getaddresses: getaddrinfo failed: Name or service not known',

It seems that it first builds the connector (which generates an error), then bootstraps artisan (overriding the config) and then getting the connector again (now with the new config)

It would seem that I need to find a better way of overriding the config :( Any suggestions would be great!

[sinnbeck]

Alas. There seems to be no viable method of doing this currently :(
Fingers crossed for either a config file for artisan or even better a service provider, someday.

Seems like it was reverted for being to generic: #27418

I indeed fear there's not a viable way to do this atm.
