如何在 Terragrunt 中引用私有 git 存储库的特定分支？

Question

I want to refer to a feature/IaC (any specific branch other than the main) branch of a multibranch private git repo as a source parameter of Terragrunt's configuration file .

Here is a piece of code from my terragrunt.hcl file

terraform {
 source = "what_link_to_put_here?"
}

Thanks in advance.

As official docs said :

By default, Terraform will clone and use the default branch (referenced by HEAD) in the selected repository. You can override this using the ref argument. The value of the ref argument can be any reference that would be accepted by the git checkout command, such as branch , SHA-1 hash (short or full), or tag names. The Git documentation contains a complete list.

So:

source = "git::https://example.com/vpc.git?ref=xxx"  //xxx is a branch name.
