Enable WebDriver on Synology

[Lunchtime0614]

I have the basic changedetection.io running within a docker container on my synology nas by following https://mariushosting.com/how-to-install-changedetection-on-your-synology-nas/. My synology is running DSM 6.2.4-25556 Update 5. However if I run the below scripts, the second one doesn't complete and it just says interrupted.

Any thoughts on how to correct the issue?

`docker run -d
--name selenium
--restart unless-stopped

--shm-size="2g"
selenium/standalone-chrome-debug:3.141.59

docker run -d
--name changedetectionio
--restart unless-stopped
--link selenium
-p 5000:5000
