Dockerfile

FROM wodby/wordpress-php:7.2-dev-4.12.5

COPY ./web /var/www/html/web

When I hit the localhost url I get a 404 from Nginx. If I ssh into the nginx container, I see that there is no web folder(expected, since I am commenting out the volumes in the nginx section of the docker-compose.yml) I don't see why is it needed there, since it's just proxying to the php container where I have backed the wordpress files, via the Dockerfile

what I am missing? why does the nginx container need to have access to the WordPress codebase? I want the php(WordPress) to be stateless, and that is why I am backing in the Wordpress files.

@csandanov any insight into this issue? thanks in advance.

I don't see why is it needed there, since it's just proxying to the php container where I have backed the wordpress files, via the Dockerfile

it's needed because you have static files in the codebase (WP core, plugins, themes), plus you have wp-content/uploads directory.

got it, thanks.
