Note that this sounds good but is not good at all when hooking tasks on cap deploy (see this article Show archive.org snapshot ). Make sure to hook your calls properly when using this.

cap deploy:migrations

Little is known what happens when the deployment goes through, but a migration or a rake task afterwards fails. Please update this note when you find out.
