storage directory creation causes permission issues with bref/php-82-fpm-dev:2

[aknosis]

When storage directories are created for the first time they get created as root:root (due to being executed by bref hooks).

The issue is that web requests cannot write to the storage directory because fpm runs under the nobody user and you end up with errors like below.

If I delete /tmp/storage after initial creation and fire a web request, it will happily create the storage directories as nobody:nobody.

Curious on thoughts of how to solve this.

Thank you for the detailed report and investigation!

Maybe a simple fix could be to chmod 777 the storage dir? Any downside?

[georgeboot]

Is this only an issue on the dev images, or on all fpm images?

[mnapoli]

oh good point!

I tested in Lambda with php-82-fpm and it seems that everything is run under sbx_user1051. This means that the initial bref startup and the fpm user are both the same so this won't be an issue in Lambda.

777 perms on storage will work, but I am curious why are we assigning the user to nobody?

[mnapoli]

but I am curious why are we assigning the user to nobody?

IIRC this is because when running in Docker, things run as root and FPM doesn't like running as root.

Maybe a simple fix could be to chmod 777 the storage dir? Any downside?

I'm fine with this, I don't foresee any negative impact in the dev image or in Lambda
