Terraform init is failing when trying to download the module from another GitHub repo (fro same organization) for GitHub Actions

Terraform

Hello,

I am setting up a new IaC code base (Terraform) for Azure, and I created a parent terraform module and my I used the User-Assigned-Managed-Identites for setting the authentication for my GitHub repo and the workflow (reference: here)

When I create local terraform module within my repo, and add it as a source from within the same repo, it worked fine no issues. However when I moved the terraform module to another Git Repo and when I use that as a source (as shown below):

module "postgres-server" {
  source              = "git::git@github.com:MyOrg/terraform-modules/postgres.git?ref=1.0.0"
  location            = var.location
  name                = var.pg_server_name
  resource_group_name = var.pg_resource_group_name
}

Now my GitHub Action runner is complaining that it can’t reach the new Git repo (my source repo):

Downloading git::ssh://git@github.com/MyOrg/terraform-modules/postgres.git?ref=1.0.0 for postgres-server...
╷

│ 
╵
Error: Terraform exited with code 1.
Error: Process completed with exit code 1.

I understand my GitHub runner needs permissions to this new source repo. I am trying to understand since I am using the Azure’s User-Assigned-Managed-Identity method, how can I provide the runner the necessary permission to be able to download the remote module?

Cheers for the help community :raising_hand_man:t2::raising_hand_man:t2:

Fixed it. I will close this one out.
