» Command: graph
terraform graph command is used to generate a visual
representation of either a configuration or execution plan.
The output is in the DOT format, which can be used by
GraphViz to generate charts.
terraform graph [options] [DIR]
Outputs the visual dependency graph of Terraform resources according to configuration files in DIR (or the current directory if omitted).
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.
The -type flag can be used to control the type of graph shown. Terraform creates different graphs for different operations. See the options below for the list of types supported. The default type is "plan" if a configuration is given, and "apply" if a plan file is passed as an argument.
-draw-cycles- Highlight any cycles in the graph with colored edges. This helps when diagnosing cycle errors.
-type=plan- Type of graph to output. Can be:
-module-depth=n- (deprecated) In prior versions of Terraform, specified the depth of modules to show in the output.
