Additional information

The official PHP documentation https://www.php.net/manual/en/function.glob.php says:

Note: The GLOB_BRACE flag is not available on some non GNU systems, like Solaris or Alpine Linux.

Failing code: https://github.com/magento/magento-composer-installer/blame/master/src/MagentoHackathon/Composer/Magento/Deploystrategy/DeploystrategyAbstract.php#L345

    protected function removeContentOfCategory($sourcePath, $destPath)
    {
        $sourcePath = preg_replace('#/\*$#', '/{,.}*', $sourcePath);
        $matches = glob($sourcePath, GLOB_BRACE);
        if ($matches) {

Possible workaround is also discussed here: https://github.com/docker-library/php/issues/719
