COPY server folder when used volumes

Hi. Should I copy my server folder, when I indicate field ‘volumes’ in my container?
Now, when I use docker port (81 for my example), I see " It works!" - but must be a started page!
Then, I thought “Maybe this is some kind of local serving and not docker?”, but when I stoped all docker docker stop $(docker ps -a -q) this port was not working.
I decided that I would connect to a random index.php in docker /var/www/myserv, not my server folder.

I feel like you keept like 95% of the context for yourself :slight_smile:
I am afraid you will need to share more details.
