Set config variable (noob)

Hello,
Sorry for noob question but I would like to preconfigure rocket.chat before deploy, like it said in this topic: Environment Variable Setting Id's

I notice all settings I needed.

But simply, I don’t know how to do to set.

Thanks!

If you know the variable id’s you want, you can set them as an environment variable.

Native:
VARIABLE_ID=value

Docker:
docker run -e VARIABLE_ID=value

Kubernetes:
helm install stable/rocketchat --set config.VARIABLE_ID=value

Thanks a lot for your quick answer but I forgot important.

I use snap installation.

So for example, Site_Name=newname . How I can set setting?

Thanks!
