Docker CLI Image - Permission issues. #908
Description
Possibly related to #906.
The cli:latest docker image doesn't have the xfs user (assigned to UID 33). When trying to run CLI commands to install plugins, I get permission errors:
test_wpcli-1 | Success: WordPress installed successfully.
test_wpcli-1 | Warning: Unable to create directory wp-content/uploads/2024/07. Is its parent directory writable by the server?
test_wpcli-1 | Installing Contact Form 7 (5.9.6)
test_wpcli-1 | Downloading installation package from https://downloads.wordpress.org/plugin/contact-form-7.5.9.6.zip...
test_wpcli-1 | Unpacking the package...
test_wpcli-1 | Warning: Could not create directory. "/var/www/html/wp-content/upgrade"
test_wpcli-1 | Warning: The 'contact-form-7' plugin could not be found.

test_wpcli-1 | Warning: Failed to activate plugin. Contact Form 7 to Odoo connector requires 1 plugin to be installed and activated: contact-form-7. .
test_wpcli-1 | Error: No plugins activated.
This user used to have a shared UID with the www-data user (in the base Wordpress container), but the xfs has been removed.

This means I cannot install plugins, as there isn't a user that has access to these files.

I can no longer use the xfs in user as the CLI user.
I am unsure if the xfs was supposed to share the UID of the www-data to ease permission issues, or if this was just a happy coincidence and another solution needs to be used.
Workaround
Use an older CLI image, eg: wordpress:cli-2.9.0-php8.3 resolves this issue.
