Update Wordpress core and plugin or theme when running on Docker

I’m running a Wordpress website on Docker but for some reason it can not auto update core / plugin / theme.

It asked for FTP, but maybe it lost permission. Default USER is www-data, Alpine image UID is 82 and Debian image is 33.

So I change owner to www-data:

$ sudo chown -R 33:33 /opt/stack/wordpress/html

Now it works.
