Dependency Resolution (Imports / Exports / Nested Stacks)

[afronski]

More complicated CloudFormation environments consists of multiple files. Also there are nested stacks available for us, in order to increase reuse.

Dependencies between those stacks are mostly bound to:

• Imports and exports.
• Nested stacks availability.

We would like to:

• Detect uniqueness for exported values across multiple files in the project.
• Detect import and export dependencies between multiple files (predicable, valid execution order).
• Validate nested stacks usage and its presence, also for proper execution order.
