How to call Terragrunt HCL files from Terratest Go script?

I have a terragrunt script which is working fine after running terragrunt apply-all command line but same thing i am not able to do/invoke form Go script. using TgApplyAll function

Below is my Go script Working terragrunt script is kept in D:\vertica-terragrunt-US-286094-Modules\with-infra location and it is working fine with manual terragrunt apply-all command but from Go script i am getting error

enter image description here

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 ?

Solution

  • 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.
