Terraform module wrapper

Read any Terraform module and wraps all its parameters into an object variable and also generates a passthrough module source.

Usage

$ tfmodulewrap 
  -add-defaults
        Add default values
  -ignore-vars string
        Variables to ignore
  -module-path string
        Path containing the module
  -module-var string
        Variable for the module configuration

Example

Using it on Cloud Foundation Fabric's net-address module:

$ tfmodulewrap modules/net-address -add-defaults=true

Result:

    # Map of internal addresses used for Private Service Access.
