all user data missed after changing mount volume in docker

The issue

I had sucessfully installed a flarum site by using RikoDEV's docker image This site has been smoothly ran for half a year.

Below is part of the config for the flarum docker container:

services:
  flarum:
    image: ghcr.io/rikodev/flarum-docker:latest
    container_name: flarum
    env_file:
      - flarum.env
    volumes:
      - ./data/flarum/public/assets:/flarum/app/public/assets
      - ./data/flarum/extensions:/flarum/app/extensions
      - ./data/flarum/storage/logs:/flarum/app/storage/logs
      - ./data/flarum/nginx:/etc/nginx/flarum
      - ./data/flarum/vendor:/flarum/app/vendor
      - ./data/flarum/composer.json:/flarum/app/composer.json
      - ./data/flarum/composer.lock:/flarum/app/composer.lock
    ports:
      - 8080:8888
    depends_on:
      - mariadb
      - meili

I did the following things and lost all forum settings and posts:

copy all files except assets in public from docker container to local directory ./data/flarum/public
- assets is already in local directory and mounted to docker container, so no need to copy
- three files were copied: index.php, web.config, and .htaccess
change docker-compose.yml to mount the entier public directory instead of only the assets

./data/flarum/public/assets:/flarum/app/public/assets
to

./data/flarum/public:/flarum/app/public

Then after restart the flarum, I find that the forum is re-initilized and all user data, including forum settings, user profile and all posts are gone. I tried to resotre all changes and restart the flarum but all those missing data won't come back. I don't see anything in the storage/logs.

Can anyone please help me resolve this problem? Thanks!

Can you manually check whether there is data in your database?

Aside from that, this has nothing to do with Flarum and everything with your docker environment. Best bet is to open an issue on the git repository of the image you use and asking what can cause a wipe of data.

Thanks for the hint! I finally figured out.

In that docker container, a startup script will check the existance of /flarum/app/public/assets/rev-manifest.json, and it will re-initilize the flarum if this file does not exist, which will wipe off mysql database. Somehow the docker has problem in maping/volume the subdirectory in my case. I found that only few files in assets were mapped, so the startup script can't find assets/rev-manifest.json, and always re-inililized flarum on start up, no matter what changes were made previously.

Now that I have added a volume mapping of assets in docker yml and fortunately find a backup of mysql database and now my site runs normally.

Thanks for the help!
