How to use a field from a Terraform multi-fields Output in Terratest

[arimaverick]

Hi,
I am printing all the attributes of a resource in Terraform via the following: value = "<resource_type>/<logical_name>"
for example value = aws_instance.web.
However when I get the output in Terratest I am getting it as a string which actually contains map[]. Hence any golang map activities to get particular attribute of that output fails.

Small Test:

output "aws_vm_details" { value = aws_instance.web }

awsVMDetails := terraform.Output(t, terraformOptions, "aws_vm_details") t.Logf("AWS_VM_DETAILS: %s of type %s", awsVMDetails["ami"], reflect.TypeOf(awsVMDetails))

I get the error in that case: non-integer string index "ami"
awsVMDetails is returned as string
Kindly help me to find the solution to get/interpret a particular field from a Terraform Output that provides multiple fields.

Hi,
I think it depends on which are keys and values of map:

• can be used OutputMap for string keys / values
• output can be read as map[string]interface{} and then casted to expected format
• can be used reading as JSON and then deserialized
