从terraform代码中的Azure DevOps的现有项目中获取存储库id

Question

I need to get the repository id of an existing project to work on that repo. There seems no other way than using Azure DevOps REST API.

I tried to utilize the REST API to get the repo id in my terraform code:

data "http" "example" {
  url = "https://dev.azure.com/{organization}/{project}/_apis/git/repositories?api-version=6.0"

  request_headers = {
    "Authorization" = "Basic ${base64encode("PAT:${var.personal_access_token}")}"
  }
}

output "repository_id" {
  value = data.http.example.json.value[0].id
}

It yields error while I was running terraform plan:

Error: Unsupported attribute
line 29, in output "repository_id":
29:   value = data.http.example.json.value[0].id

I tried also with jsondecode (jq is already installed):

resource "null_resource" "example" {
  provisioner "local-exec" {
    command = "curl -s -H 'Authorization: Bearer ${var.pat}' https://dev.azure.com/{organization}/{project}/_apis/git/repositories?api-version=6.0 | jq '.value[0].id'"
    interpreter = ["bash", "-c"]
  }
}
output "repo_id" {
  value = "${jsondecode(null_resource.example.stdout).id}"
}

That did not work either!!

Azure DevOps REST API works fine, I just cannot fetch the value from the responce into terraform! What would be the right code or can it be done without using REST API!

Thank you!

To proper way to interact with external API and return its output to TF is through external data source . TF docs linked provide example of how to use and create such a data source.
