wp/content has right ownership

[gammaw]

Description: currently wp-content is owned by root which prevents from uploading media because wp-content/uploads is not writible by www-data user inside the Wordpress container

Root cause: COPY command in Dockerfile and volumen setup (--volume) in docker run. Btw, why do we need both?

Workaround:
SSH into Wordpress container: docker exec -it lahma-wp /bin/bash
Change ownership: chown -R www-data:www-data wp-content/

Can be fixed manually. Enough for now
