I have the above error in my API. I am using Laravel version 8 and I deployed the API on the Google Cloud App Engine.

I followed the directions of this tutorial. I am trying to store a generated file in the /tmp folder and upload it to Google Cloud Storage. Following the tutorial to Set up Stackdriver Logging and Error Reporting but I got

There is no existing directory at ".../storage/logs" and it could not be created: Read-only file system

Please I have very little DevOps knowledge and I appreciate any help you can offer.

This is my app.yaml file

runtime: php73

env_variables:
  ## Put production environment variables here.
  LOG_CHANNEL: stackdriver
  APP_KEY: my_app_key
  APP_STORAGE: /tmp
  VIEW_COMPILED_PATH: /tmp
  SESSION_DRIVER: cookie

In my filesystems.php file I set the symbolic link to the /tmp folder

'links' => [
        public_path('storage') => storage_path('/tmp'),
],

and this is my composer.json file

    it seems similar to this [question](https://stackoverflow.com/q/59511828/8753991) – JM Gelilio Apr 20 '21 at 20:08
  • Yes, @JohnMichaelGelilio you are right, but, I could not find a solution there. I have tried changing the permission in the ```composer.json``` file. The tutorial referenced ```laravel version 5.4``` and I am seeking someone who has deployed it with a later version. I have very little cloud knowledge. – aghwotu Apr 20 '21 at 20:43

GAE doesn't have access to the local files/storage in Standard environment and would usually give an error of Read-only file system in such situations.

Since you are following an official Google Tutorial which is for GAE Standard, confirm that the path $app->useStoragePath(env('APP_STORAGE', base_path() . '/storage')); (from the tutorial) in your code, actually points to a path on google cloud env and not your local file structure.
