I am trying to use Terraformer ( https://github.com/GoogleCloudPlatform/terraformer ) to import some of our legacy into Terraform for ease of maintainability going forward. I keep running into a few issues though.
Current State - I am on Terraform version 1.1.7 with a remote backend configuration on S3. The desired end state is to use Terraformer to generate configurations for the legacy infrastructure, and include them as a separate module in the backend remote state.
Problem(s) -
- Terraformer only seems to work with Terraform version 0.21.31, and the state files it generates also confides in this. I did some lookup and the standard suggestion here was to use https://github.com/tfutils/tfenv and have multiple Terraform versions. However it seems that TF 0.21.31 does not support provider plugin sources, which means I can't install the Hashicorp AWS provider plugin, without which, Terraformer can't work. So I am stuck in a deadlock here. Curious to know how others solved it?
- Assuming I do somehow manage to solve the version issue, Terraformer seems to generate a local state file. Now, since my remote backend is on S3, how do I merge this local state file to the remote backend state file, so that Terraform realises that I am just planning to import some infra, and not re-create them?
Any help here would be much appreciated. Thanks in advance!
Please let me know if we need some more additional info for a better prognosis!
