Hi, It’s possible to use variable when create new volumes container?  
Whit this, i could create named volumes even using scaleup on my service.

Something like this:

Variable substitution only works Rancher Compose and doesn’t work in the UI. The substitutions are based on environment variables from the host calling Rancher Compose, so `$CONTAINER_NAME` wouldn’t be set per container like I think you’re expecting.

Ok, and has another option to set a name to volume container based on main container name?

I think you’re asking for an option to set each name of a volume to be the container name. This option does not exist in Rancher today. You could add an enhancement request in our github repo.
