[Howto] collabora Code 2.0 connect to nextcloud

I read on the collabora website that we must add an user to the dockercommand, like this:

docker run -t -d -p 127.0.0.1:9980:9980 -e ‘domain=cloud\.nextcloud\.com’ -e ‘username=admin’ -e ‘password=123456’ --restart always --cap-add MKNOD collabora/code

after execute this command collabora works fine for me…
