How to setup DRAWIO_CONFIG variate in docker-compose.yaml

[pengshp]

Hello!
DRAWIO_CONFIG variate,
What should I write after the variable?
I can't understand! it's a path for json file or content of json file?
Please give example DRAWIO_CONFIG for self-contained.

Thanks!

You don't set it in the compose, you set window.DRAWIO_CONFIG in the PreConfig.js file and mount it into docker.

@pengshp just put json as string:

services:
  drawio:
    image: jgraph/drawio:28.2.3
    environment:
      - DRAWIO_CONFIG: '{"customFonts":[]}'

    # ...

Note

DRAWIO_CONFIG used to construct PreConfig.js file:

docker-drawio/main/docker-entrypoint.sh

Line 67 in e12d208

echo "window.DRAWIO_CONFIG = ${DRAWIO_CONFIG:-null};" >> $CATALINA_HOME/webapps/draw/js/PreConfig.js
