terraformer

https://github.com/googlecloudplatform/terraformer shutdown earlier this year, but this tool might help others to at least reverse-engineer their Github, Gitlab Gitea, Forgejo into infrastructure-as-code.

The Terraformer tool was the biggest blessing when I had to reverse engineer our AWS stack into .tf modules. Shoutout to the Waze team for creating it! https://github.com/GoogleCloudPlatform/terraformer We built out a large serverless stack on AWS, and we got a request from higher ups to convert it all into Terraform modules for portability and transparency purposes. The Terraformer tool pulled in the entire stack and spit out the whole thing into tf files in less than 30 seconds. Everyone was super impressed on the team lol.

And here comes Terraformer: https://github.com/GoogleCloudPlatform/terraformer It doesn't import anything, but generates the .tf files for you. Disclaimer: I have used that, but not for GitHub.

Seems like a potentially useful tool. Another related approach is https://github.com/GoogleCloudPlatform/terraformer ("reverse Terraform"), which might be better if your end goal is to build Terraform scripts for existing infra. However I like the idea of using these visualizations to grok or monitor infra; say as a Platform or Security engineering team, you might want to keep an eye on specific classes of resource like storage buckets, load balancers, etc.

> I was really hoping this was "automatically generate Terraform FROM AWS" to import existing resources. You might be interested in Terraformer. https://github.com/GoogleCloudPlatform/terraformer

I haven't found a good way to handle resources that were created outside TF. Like a EC2 instance running in staging to debug an issue, but then forgotten about. They don't exist in TF state or config so TF simply ignores them. I've tried terraformer[1], but I can't tell how well maintained that is (it failed to get my creds, I had to modify the code to fix it, and then it crashed with an obscure error). Anyone have a good approach? 1. https://github.com/GoogleCloudPlatform/terraformer

I wasn't aware of terraformer[1] - anyone have any experience with it? [1] https://github.com/GoogleCloudPlatform/terraformer

How does this compare to https://github.com/GoogleCloudPlatform/terraformer -- looks like it is more continuously updating and user friendly?

For the latter: https://github.com/GoogleCloudPlatform/terraformer

Check out Terraformer: https://github.com/GoogleCloudPlatform/terraformer This has been instrumental in importing and generating configs from existing infrastructure.

Yes! Its great to capture a bespoke configuration in code. You may already know this but there is a tool called terraformer that has limited support for doing just this: https://github.com/GoogleCloudPlatform/terraformer
