Outputs the visual graph of Terraform resources. If the path given is
|
|
the path to a configuration, the dependency graph of the resources are
|
|
shown. If the path is a plan file, then the dependency graph of the
|
|
plan itself is shown.
|
|
|
|
The graph is outputted in DOT format. The typical program that can
|
|
read this format is GraphViz, but many web services are also available
|
|
to read this format.
|

|

Options:
|
|
|
|
-module-depth=n The maximum depth to expand modules. By default this is
|
|
zero, which will not expand modules at all.
