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.
-no-color - If specified, output won't contain any color.
-type=plan - Type of graph to output. Can be: plan, plan-destroy, apply, legacy.
The output of
terraform graph is in the DOT format, which can easily be converted to an image by making use of
dot provided by GraphViz:
$ terraform graph | dot -Tsvg > graph.svg
