README

InfraMap

Read your tfstate or HCL to generate a graph specific for each provider, showing only the resources that are most important/relevant.

Cloud Providers

We support certain providers. This allows us to better represent information that comes from these providers.

If your state file or HCL is from a provider we do not support, the resulting representation will simply be all resources present without any simplification or refinement.

Support:

Terraform: 0.12.28

Provider	State	HCL
AWS	Yes	Yes
FlexibleEngine	Yes	Yes
OpenStack	Yes	Yes
Google	WIP	WIP
AzureRM	WIP	WIP

Installation

Development

You can build and install with the latest sources, you will enjoy the new features and bug fixes. It uses Go Modules (1.13+)

$ git clone https://github.com/cycloidio/inframap
$ cd inframap
$ go mod download
$ make build

Usage

The inframap --help will show you the basics.

The most important subcommands are:

• generate: generates the graph from STDIN or file.
• prune: removes all unnecessary information from the state or HCL (not supported yet) so it can be shared without any security concerns

Example

Visualizing with dot

$ inframap generate --tfstate state.tfstate | dot -Tsvg > graph.svg

or from the terminal itself

$ inframap generate --tfstate state.tfstate | graph-easy

or from HCL

$ inframap generate --hcl config.tf | graph-easy

or HCL module

$ inframap generate --hcl ./my-module/ | graph-easy

How does it work?

For each provider, we support specific types of connections; we have a static list of resources that can be nodes or edges. Once we identify the edges, we try to create one unique edge from the resources they connect.

For a state file, we rely on the depends_on key and, for HCL we rely on interpolation to create the base graph one which we then apply specific provider logic if supported. If not supported, then basic graph is returned.

AWS

Note: We are currently investigating/trying to implement the grouping (https://github.com/cycloidio/inframap/issues/6) and connections based on iam resources (https://github.com/cycloidio/inframap/issues/11).

About Cycloid

Cycloid is a European fully-remote company, building a product to simplify, accelerate and optimize your DevOps and Cloud adoption.

We built Cycloid, your DevOps framework to encourage Developers and Ops to work together with the respect of best practices. We want to provide a tool that eliminates the silo effect in a company and allows to share the same level of informations within all professions.

Cycloid supports you to factorize your application in a reproducible way, to deploy a new environment in one click. This is what we call a stack.

A stack is composed of 3 pillars:

1. the pipeline (Concourse)
2. infrastructure layer (Terraform)
3. applicative layer (Ansible)

Thanks to the flexible pipeline, all the steps and technologies are configurable.

To make it easier to create a stack, we build an Infrastructure designer named StackCraft that allows you to drag & drop Terraform resources and generate your Terraform files for you.

InfraMap is a brick that will help us to visualize running infrastructures.

The product comes also with an Open Source service catalog (all our public stacks are on Github) to deploy applications seamlessly. To manage the whole life cycle of an application, it also integrates the diagram of the infrastructure and the application, a cost management control to centralize Cloud billing, the monitoring, logs and events centralized with Prometheus, Grafana, ELK.

Don't hesitate to contact us, we'll be happy to meet you !
