terraform-provider-kubernetes-alpha VS terraformer

Open since March with no progress on that issue but I just noticed 0.4 adds a fallback for OpenAPI validation failure ... so need to test if this is fixed (after almost 2 months) - https://github.com/hashicorp/terraform-provider-kubernetes-alpha/issues/181#issuecomment-852037406

You can use the new Kubernetes alpha provider to apply any YAML manifest against your cluster. It’s very new and still in Alpha or Beta but it solves this exact problem. Check it out: https://github.com/hashicorp/terraform-provider-kubernetes-alpha

or, alternatively, for more complex projects, check out terraformer, a CLI tool to import/update your tfstate from existing infrastructure.

‍Terraformer is a CLI tool developed by Google that generates Terraform files from existing infrastructure (reverse Terraform), simplifying the process of adopting Terraform in existing environments and speeding up the initial setup process. Terraformer supports multiple cloud providers, including AWS, Google Cloud, Azure, and others.

Looking into efficient ways to import existing infrastructure. Using Terraformer to get the everything into Terraform and then refactoring into modules, for_each, etc. using moved blocks seems like it would be a good approach. Refactoring them to use existing modules from providers will take a little work and likely going back and forth with terraform plan, and assuming many things won't translate straight across because of what resources a module might be creating and how they are creating them.

We had thought about the ability to convert HCL to Go, but not much thought in querying existing infra to generate HCL (like terraformer). If you want to experiment building on top of Lingon then please go ahead! I’d be happy to help provide the context from Lingon.

If "ClickOps" is your starting point, as you mention, you could try creating a new scratch cloud provider account, do all your "ClickOps", then use a TF export tool (e.g., Terraformer) to see the exported TF resources to find all the references to other TF resources in the cloud resource dependency chain.

I haven't worked with any of the ones that purport to work with AWS, but a quick Google shows terraformer and Terracognita as options - maybe look into trying those out?

This maybe a bit more complicated if you're not into coding/terraform but I'd use terraformer to convert all of your infrastructure from implementation to code while in AWS, then switch providers and with a bit of jiggly of the code implement your infra into gcs as IaC and keep it that way if/when you switch again.

Maybe terraformer could help. I never tried it personally . https://github.com/GoogleCloudPlatform/terraformer
