Issue with DRAWIO_LIGHTBOX_URL and local viewer

[pmenga52]

Hi, I would like to use the internal readonly viewer of the docker server (lightbox?) dealing with the docs ( https://github.com/jgraph/docker-drawio/tree/dev/self-contained ), I tested several settings according to the DRAWIO_* parameters

I just installed last version of docker-drawio (22.04) on a local machine ( local DN draw.fc) with the simpliest docker-composed.yml for a local machine

docker-compose.yml

version: '3.5' services: drawio: image: jgraph/drawio container_name: drawio restart: unless-stopped ports:

• 80:8080
• 443:8443 environment: DRAWIO_SERVER_URL: http://draw.fc DRAWIO_BASE_URL: http://draw.fc/

  DRAWIO_VIEWER_URL: http://draw.fc

  DRAWIO_LIGHTBOX_URL: http://draw.fc

  healthcheck: test: ["CMD-SHELL", "curl -f http://draw.fc || exit 1"] interval: 1m30s timeout: 10s retries: 5 start_period: 10s

• first test: DRAWIO_VIEWER_URL and DRAWIO_LIGHTBOX_URL commented _drawio | window.DRAWIO_SERVER_URL = 'http://draw.fc'; drawio | window.DRAWIO_BASE_URL = 'http://draw.fc'; drawio | window.DRAWIO_VIEWER_URL = ''; drawio | window.DRAWIO_LIGHTBOXURL = '';

on the menu: File/Publish/Link + lightbox checked, -> the url link start with https://viewer.diagrams.net (not what I want) File/Publish/Link + lightbox unchecked, -> the url link starts with http://draw.fc but still on edit mode (not read-only)

• second test: DRAWIO_VIEWER_URL=http://draw.fc DRAWIO_LIGHTBOX_URL commented: same results

• third test: DRAWIO_LIGHTBOX_URL=http://draw.fc --> the client stops with the error message "Error loading file" - no file selected

So at the end, I don't know if the DRAWIO_LIGHTBOX_URL is correctly set (and how it could retrieve the /js/viewer.min.js

DRAWIO_LIGHTBOX_URL in current version must be different from the BASE/SERVER URL (e.g, a different subdomain)

In the next version, we'll remove this limitation
