Visual representation of a Terraform plan, showing added, deleted and updated resources.

Installing

This extension is available for free in the Visual Studio Code Marketplace

Generate Terraform graph

You can generate a Terraform graph in three steps:

1. If you haven't done so already, install Terraform
2. Open command palette using Ctrl+Shift+P
3. Select command Generate Terraform Graph

This will open a terminal in your current working directory and run the following command:

terraform plan -out=plan && terraform show -json plan > plan.tfgraph

You can customize the command using the terraform-graph.command configuration option, e.g. in .vscode/settings.json:

{
    "terraform-graph.command": "terraform plan -out=plan && terraform show -json plan > plan.tfgraph"
}

If a file is currently open in your editor, the command will be run in the directory of the file.

The command generates two files:

1. a Terraform plan file, which can be later applied using terraform apply command
2. a .tfgraph file (which is actually a simple json file)

Visualize Terraform graph

You can visualize your terraform graph by simply opening the .tfgraph file in your editor.

On the left you can see all the resource changes. Red are the deleted resources, green the added ones and orange the updated ones.

When clicking on a resource, you can see on the left the properties that changed, with the same color mapping.
