Problems setting up docker on synology NAS. Apache AH00072

[unickq]

Hey there,

I'm trying to launch your app on my NAS and facing with apache issues. It's a Synology 218+ nas with the latest DSM 8, which has docker 24 and 2Core Intel Celeron J3355 and 10gb ram

Config for YML - latest prod - https://github.com/simjanos-dev/LinguaCafe/blob/main/docker-compose.yml

.env:

DB_ROOT_PASSWORD=rootpwd

When I start without .env - MySQL doesn't start - container for service mysql is unhealthy

From what I found, it doesn't seem like 80 port. From this I found that I need to edit /etc/apache2/ports.conf. But I can't, your dockerfile is built with --no-install-recommends and seems like doesn't have any text editor for Debian GNU/Linux 12 (bookworm).

I can't install anything because no root access and sudo is not available. And setting it up with su - doesn't work because of adduser --ingroup laravel --disabled-password in dockerfile.

Container crashes immediately, but when stud down DB container - I'm able to log in and

.                                                     

When the http daemon starts, it tries to bind the 80 port, which is a port within the system assigned ports and as such it can only be accessed by root. 
In order to be able to run it as a non-root user you could change the port to a non-reserved one (higher than 1024), or use an account with enough privileges.

But I don't know how to debug it for now - I need to build it myself, using my own docker cloud, and then PR with port up.

However, everything is working on my Mac 😿

omg, after 4 hours of debugging

user: root added to main app worked

services:
  webserver:
    image: ghcr.io/simjanos-dev/linguacafe-webserver:${VERSION:-latest}
    user: root

Hi!

Im not sure why it does not work on your nas.

I think using root as a user will cause other permission problems, for example when trying to import a book.
