WhiteBoard WebSocket Server Container Image HealthCheck Port ignores Config

[gajanak]

The default image for the whiteboard server
ghcr.io/nextcloud-releases/whiteboard:stable

defines a health command
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3
CMD node -e "require('http').get('http://localhost:3002', (res) => { process.exit(res.statusCode === 200 ? 0 : 1) })"

If the Port is Changed with the configuration variable PORT - the check always fails.

Perhaps its possible to use the ENV Var PORT instead of 3200 ?

Thanks in advantages.
