Running ConvertX with an unprivileged, non-root user

[thecodygriffin]

Has anyone had any success with running ConvertX with an unprivileged, non-root user.

For example, my compose file:

services:
  convertx:
    image: ghcr.io/c4illin/convertx:v0.15.1
    user: 171:1223                 # added this this line to run as an unprivileged, non-root user
    group_add:
      - 108
    container_name: convertx
    restart: unless-stopped
    environment:
      - TZ=America/New_York
      - JWT_SECRET=${JWT_SECRET} # will use randomUUID() if unset
      - HTTP_ALLOWED=true # uncomment this if accessing it over a non-https connection
      - ACCOUNT_REGISTRATION=false
      - ALLOW_UNAUTHENTICATED=false
      - AUTO_DELETE_EVERY_N_HOURS=168
      - FFMPEG_ARGS=-hwaccel vaapi
      - LIBVA_DRIVER_NAME=iHD
      - HIDE_HISTORY=false
      - LANGUAGE=en
      - UNAUTHENTICATED_USER_SHARING=false
      - MAX_CONVERT_PROCESS=0
    volumes:
      - /path/to/convertx/data:/app/data
      - /usr/lib/x86_64-linux-gnu/dri:/usr/lib/x86_64-linux-gnu/dri:ro
      - /usr/lib/x86_64-linux-gnu/libigdgmm.so.12:/usr/lib/x86_64-linux-gnu/libigdgmm.so.12:ro
    devices:
      - /dev/dri:/dev/dri
    networks:
      - convertx_net

networks:
  convertx_net:
    external: true

Although the container will start and run, various conversions that require programs to start on the fly, such as javadlx for LibreOffice when attempting an Apple Pages document to Microsoft Word document conversion, will fail.

stderr: Warning: failed to launch javaldx - java may not function correctly
LibreOffice 25.2 - Fatal Error: The application cannot be started. 
User installation could not be completed. 

Failed to convert ./data/uploads/1/14/AppleDoc.pages from pages to docx using libreoffice. error: Error: Command failed: soffice --headless --infilter="Apple Pages" --convert-to docx:MS Word 2007 XML --outdir data/output/1/14 ./data/uploads/1/14/AppleDoc.pages

Has anyone manipulated the Dockerfile or found a way around this issue?

I suspect the behavior I am experiencing is similar to what was reported in #425. I honestly do not know if this is a bug or expected behavior when running as an unpriviledged, non-root user.
