Terragrunt 从特定分支下载模块

Question

我最近开始使用 terragrunt 并且一直想知道是否可以从特定分支而不是特定标签（或除标签之外）而不是默认情况下下载模块 master

从主站下载特定标签：

terraform {
  source = "git@github.com:<repo>/infrastructure-modules.git//gcp/bucket?ref=v.0.0.1"
}

从 repo 下载特定分支？

# Pseudo code
terraform {
  source = "git@github.com:<repo>/infrastructure-modules.git//gcp/bucket?ref=v.0.0.1%branch=test"
}

Answer 1

查看 terragrunt cli/download_source_test.go 源代码，没有明显的方法来指定分支。

这意味着您需要向该分支添加一个标签，并将该标签用作 ref。
也就是说，首先检查 ref=<mybranch> 是否有效。

但是直接引用分支名的OP potatopotato confirms 是不行的

I just made changes on branch, and:
git add
 git commit
 git tag -a 'v1.branch'
 git push --follow-tags -u origin <branch_name>
and I could use the tag reference to the branch, not master.

和German Dautin's points to Terraform / Module Sources / Selecting a Revision.

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:
module "vpc" {
  source = "git::https://example.com/vpc.git?ref=v1.2.0"
}
The value of the ref argument can be any reference that would be accepted by the git checkout command, including branch and tag names.

因此可以使用分支名称。

Answer 2

我能够使用以下方法指定一个分支：

terraform {
  source = "git@github.com:<repo>/infrastructure-modules.git//gcp/bucket?ref=branch-name"
}
