Getting error as below

''' github.com/gruntwork-io/terratest/modules/terraform.TgInvalidBinary.Error(...) c:/go/pkg/mod/github.com/gruntwork-io/terratest@v0.30.15/modules/terraform/errors.go:12

Detailed error func (err TgInvalidBinary) Error() string { return fmt.Sprintf("terragrunt must be set as TerraformBinary to use this function. [ TerraformBinary : %s ]", err) } '''

I used same code which i used to call terraform code from terratest Go script for calling terragrunt code also but it is not working

Can anyone help me / direct me to location like how to invoke working terragrunt code from terratest Go script ?

  • On a side note, have you really "set terragrunt as TerraformBinary to use that function" as the error message suggests? – kostix Oct 29 '20 at 09:48
  • @kostix I am not getting how to set "set terragrunt as TerraformBinary" example code is not available for that anywhere ... So struggling hard... – Sanjay Gayakwad Oct 29 '20 at 09:56
  • A couple notes: 1. There's no such thing as a "go [script](https://en.wikipedia.org/wiki/Scripting_language)". 2. [Don't paste images of code](https://meta.stackoverflow.com/questions/303812/discourage-screenshots-of-code-and-or-errors). – Jonathan Hall Oct 29 '20 at 11:07

Hello You need to set TerraformBinary to terragrunt in the terraform options like this :

terraformOptions := &terraform.Options{

    TerraformDir: "D:/vertica-terragrunt-US-286094-Modules/with-infra",
    TerraformBinary : "terragrunt",
}

because the default binary is terraform and TgInvalidBinary occurs when a terragrunt function is called and the TerraformBinary is set to a value other than terragrunt.

here's a ref

https://godoc.org/github.com/gruntwork-io/terratest/modules/terraform#TgInvalidBinary

https://github.com/gruntwork-io/terratest/blob/master/modules/terraform/cmd.go
