tf2yed

Convert Terraform graphs to GML for use with yEd.

Usage:

tf2yed input.dot [output.gml]

If no outputs is specified, output gous to stdout.

Advanced

Build an executable with:

mvn clean package
cat script/stub.sh target/tf2yed-*-jar-with-dependencies.jar > tf2yed && chmod +x tf2yed

Move the tf2yed app to your path, then enter a Terraform directory and run:

terraform init
tf2yed <(terraform graph) > graph.gml

Open graph.gml with yEd, and execute the steps:

• "Tools->Fit Node to Label"
• "Layout->Hierarchial"

I generally order the graph bottom to top, and follow up with "Grouping->AutoGrouping" and/or "Tools->Centrality Measures" to get a good overview.
