First setup with unified container sqlite

I have a running setup from a while ago where the docker setup was still with a vikunja/api and vikunja/frontend and there I have no problems, but with the vikunja/vikunja integrated image I get permission problems. I’m following Full docker example | Vikunja

version: '3'

    image: vikunja/vikunja
      VIKUNJA_SERVICE_PUBLICURL: http://localhost:3456/
      # Note the default path is /app/vikunja/vikunja.db.
      # This config variable moves it to a different folder so you can use a volume and 
      # store the database file outside the container so state is persisted even if the container is destroyed.
      VIKUNJA_DATABASE_PATH: /db/vikunja.db
      - 3456:3456
      - ./files:/app/vikunja/files
      - ./db:/db
    restart: unless-stopped

I did

mkdir $PWD/files $PWD/db
chown 1000 $PWD/files $PWD/db

but get permission error on starting even though the files are owned by 1000

Any idea what I’m doing wrong?

Okay, eventhough user 1000 owns the files, vikunja creates vikunja.db with no permissions by default, chmod u+rw db/vikunja.db fixes it.
