internal server error after moving the docker container to another server

hi,

I wanted to move a redmine docker-compose installation to another server.
The source server is running redmine 5.0.5 with postgresql, so I created a docker-compose file on the new server:

version: '3'

services:
  redmine:
    image: redmine:5
    container_name: redmine
    restart: always
    environment:
      - REDMINE_DB_POSTGRES=postgres
      - REDMINE_DB_DATABASE=redmine
      - REDMINE_DB_USERNAME=redmine
      - REDMINE_DB_PASSWORD=topsecret
      - REDMINE_DB_ENCODING=utf8
    depends_on:
      - 'postgres'
    volumes:
      - ./redmine:/usr/src/redmine/files
      - ./redmine-config:/usr/src/redmine/config
      - ./redmine-plugins:/usr/src/redmine/plugins
    ports:
      - '3000:3000'

  postgres:
    image: postgres:14
    container_name: postgres
    restart: always
    volumes:
      - ./postgres:/var/lib/postgresql/data
    environment:
      - POSTGRES_DB=redmine
      - POSTGRES_USER=redmine
      - POSTGRES_PASSWORD=topsecret

First I started up only the database and imported the dump form the old db.
Then I rsyncd the three directories:

rsync -avz redmine root@newserver:/docker/redmine
rsync -avz redmine-config root@newserver:/docker/redmine
rsync -avz redmine-plugins root@newserver:/docker/redmine

after that I adjusted the database.yml

I can start redmine just fine, but most sites print "internal server error", for example the register page. I get this errors, but they're not really helpful for me :)

RE: internal server error after moving the docker container to another server - Added by Holger Just about 2 hours ago

The config directory of Redmine contains a lot of files which must not be edited nor preserved between Redmine updates. Instead, most of these files are part of the respective Redmine release and must be updated along with Redmine.

It seems that you have mounted / overwritten the entire config directory from an external volume in your docker config. This won't work (reliably or at all). You should only map the actual files you are configuring, usually only these files:

config/database.yml (if overwritten)
config/configuration.yml
either config/initializers/secret_token.rb or config/secrets.yml depending on your setup
