How to find all deb package dependencies?

Question

Debian

Hello everyone,
Inside the private cloud (part of the public cloud) there are virtual machines with some cloud provider modified Ubuntu 14 LTS.
Due to security requirements, virtual machines do not have access to the Internet. All installations/configurations/updates are done from some trusted node.
Task:
Need to install system components from saved packages: dpkg -i ./*.deb
The problem is that I can't find a normal way to build the package's dependencies in a digestible way, excluding those that I 100% know are installed, so that they can be download.
For example, we have some non-standard package rabbitmq-server _3.5.7-1 for which:
# dpkg -I rabbitmq-server_3.5.7-1_all.deb

new debian package, version 2.0.

RabbitMQ is an open source multi-protocol messaging broker.

Let's take the first erlang-nox dependency and inside the test machine from the cloud provider I will do:
# apt-cache depends erlang-nox

I don't understand why you do this shit.
https://help.ubuntu.com/community/AptGet/Offline/R... put all the packages in a directory, download the files with the repository meta-info and install with apt-get, it will resolve the dependencies and tell you what is missing in local directory.
