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]
Outputs the visual execution graph of Terraform resources according to either the current configuration or an execution plan.
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.
-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
-plan=tfplan- Render graph using the specified plan file instead of the configuration in the current directory.
-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.
The output of
terraform graph is in the DOT format, which can
easily be converted to an image by making use of
$ terraform graph | dot -Tsvg > graph.svg
Here is an example graph output:
