import_key variable does not insert public ssh key into ~/.ssh/authorized_keys

[scarolan]

I configured the module below using a variable to define the import_key input:

module "terraform-enterprise" {
  source  = "hashicorp/terraform-enterprise/azurerm"
  version = "0.1.0"
  # insert the 8 required variables here
  domain                        = "${var.domain}"
  key_vault_name                = "${var.key_vault_name}"
  license_file                  = "${var.license_file}"
  tls_pfx_certificate           = "${var.tls_pfx_certificate}"
  tls_pfx_certificate_password  = "${var.tls_pfx_certificate_password}"
  key_vault_resource_group_name = "${var.key_vault_resource_group_name}"
  domain_resource_group_name    = "${var.domain_resource_group_name}"
  resource_group_name           = "${data.terraform_remote_state.azure-tfe-infra.tfe_rg}"
  virtual_network_name          = "${data.terraform_remote_state.azure-tfe-infra.tfe_vnet}"
  subnet                        = "${data.terraform_remote_state.azure-tfe-infra.tfe_subnet}"
  import_key                    = "${var.import_key}"
}

But the VMs never get the content of the import_key variable inserted into ~/.ssh/authorized_keys

So that variable looks like it might only work on Ubuntu (which is a thing we'll need to call out) but also follows the schema defined here:

https://cloudinit.readthedocs.io/en/latest/topics/modules.html#ssh-import-id

Are you passing the public ssh key in directly?

[evanphx]

Yes, this needs to be documented more about the format that the value should take, namely conforming to the docs @erindatkinson listed above.

Can I second what @scarolan has stated above?
I have supplied my own public key via the import_key var and the public key is not being inserted into the ~ubuntu/.ssh/authorized_keys file.

I took at a look in the cloud-init-output.log for some ssh content and this is what it came back with:

root@tfe-vpkqok5r-primary-0:/var/log# cat cloud-init-output.log | grep -i ssh
