Interactive visualizations of Terraform dependency graphs

Project description

# Blast Radius

[![PyPI version](](

*Blast Radius* is a tool for reasoning about *Terraform* dependency graphs with interactive visualizations. Use *Blast Radius* to:
* **Learn** about *Terraform* or one of its cloud providers, through [example configurations](
* **Document** your infrastructure
* **Reason** about relationships between resources, and evaluate changes to them.

* **Interact** with this diagram (and many others) [here](

# Quickstart

Install *Blast Radius* with pip, and *Graphviz* through your system's package manager.

[...]$ pip3 install BlastRadius
[...]$ brew install graphviz

Point *Blast Radius* at an `init-ed` *Terraform* project, and connect with your browser.

[...]$ blast-radius --serve /path/to/terraform-project
* Running on (Press CTRL+C to quit)

*Alternatively*, you can launch *Blast Radius* in a docker container. (In this example, the current working directory contains a *Terraform* project.)

[...]$ docker run -it --rm -p 5000:5000 -v $(pwd):/workdir 28mm/blast-radius

# Embeded Figures

You may wish to embed figures produced with *Blast Radius* in other documents. You will need the following:

1. an `svg` file and `json` document representing the graph and its layout.
2. `javascript` and `css` found in `.../blastradius/server/static`
3. a uniquely identified DOM element, where the `<svg>` should appear.

Further details available [here](doc/

# Implementation Details

*Blast Radius* uses the [*Graphviz*]( package to layout graph diagrams, [*PyHCL*]( to parse [*Terraform*]( configurations, and [*d3.js*]( to implement interactive features and animations.

# Further Reading

* The motivations for *Blast Radius* are documented in a series of [blog]( posts: [part 1](, [part 2](, and [part 3](
* A catalog of example *Terraform* configurations, and their dependency graphs can be found at [](
