This is the php.docker file

RUN docker-php-ext-enable pdo_mysql
When I run the WordPress installation, I get error
Unable to write to wp-config.php file
It seems like PHP container didn't have the correct permissions to write to the filesystem that is on my local volume ./files.
I searched a lot and I think I am having the same problem as this one Laravel and Docker permission issue - can't save files but for WordPress.
According to above solution, I tried to add user: "1000:1000" into my docker-compose.yml but it throws following error due to docker-compose version I think
ERROR: The Compose file './docker-compose.yml' is invalid because:
services.php.build contains unsupported option: 'user'
What should be the workaround here to resolve this permission issue
