How to run terraform in azure functions.

Answer 1

The error message you are receiving may or may not be related to your attempt to use terraform in Azure Functions.

I'd initially ask whether Azure Functions is the ideal solution to the problem you're trying to solve?

Based on the fact that the functions runtime doesn't include the terraform binary in order to run tf cli commands. You may have more success using Azure Devops pipelines or Github Actions to deploy your terraform code.

Both AzDo and Github can trigger CI/CD operations via a webhook.

and

Unless I am missing something obvious, you may have to provide more context around why you're using Azure Functions for this scenario
