You need to rewrite where Laravel stores things as per step (1) and (3) in these instructions:

https://cloud.google.com/community/tutorials/run-laravel-on-appengine-standard

Briefly -

Step 1, in app.yaml you need to add:

APP_STORAGE: /tmp

Then in Step 3 you make Laravel use this. Modify bootstrap/app.php by adding the following block of code before the return statement. This will allow you to set the storage path to /tmp for caching in production.

# [START] Add the following block to `bootstrap/app.php`
/*
|--------------------------------------------------------------------------
| Set Storage Path
|--------------------------------------------------------------------------
|
| This script allows you to override the default storage location used by
| the  application.  You may set the APP_STORAGE environment variable
| in your .env file,  if not set the default location will be used
|
*/
$app->useStoragePath(env('APP_STORAGE', base_path() . '/storage'));
# [END]
