tf_validation_backend

This module shows how to fetch the backend block from a Terraform configuration file.

How to use

You can run the tf_validation_backend.go to fetch the backend name from a .tf file.

go run tf_validation_backend.go ${path_to_your_tf_file}

What's more

Actually, the function fetchBackendName in tf_validation_backend.go is just a simple demo. You can extend it to get more information about the backend configuration. As you can see, all the attributes and blocks in the backend block are parsed into the Remain field which type is hcl.Body. We can get all the information by accessing the fields of the hcl.Body.

For example, the following code prints all the keys of the attributes of the backend block.

attrsMap, _ := config.Terraform.Backend.Remain.JustAttributes()
for k := range attrsMap {
    fmt.Println(k)
}
