所以我有以下Terraform代码：'
我有以下模板文件：

#cloud-config
users:
  %{ for user in user_list ~}
  - name: ${user.username}
    gecos: ${user.username}
    ssh-authorized-keys:
      - ${user.ssh_public_key}
    lock_passwd: true
    groups: sudo
    shell: /bin/bash
  %{ endfor } 
packages:
    jp

以下Terraform代码：

...
output "users" {
  value = [for k in local.external_users : k.username]
}

data "template_cloudinit_config" "config" {
  gzip          = true
  base64_encode = true
  part {
    filename     = "cloud-init.cfg"
    content_type = "text/cloud-config"
    content = templatefile("${path.module}/templates/userdataloop.yaml", {
      user_list = local.external_users
    })
  }
…
resource "azurerm_virtual_machine" "jphostvm" {
...
os_profile {
    computer_name  = "${var.environment}-jp-${format("%02d", count.index + 1)}"
    admin_username = "deploy"
    custom_data    = data.template_cloudinit_config.config.rendered
  }

最后是以下用户（在不同的tf文件中声明）：'

locals {
  external_users = [
    {
      username       = "ian"
      ssh_public_key = data.vault_generic_secret.ian.data["key"]
    },
    {
      username       = "fred"
      ssh_public_key = data.vault_generic_secret.fred.data["key"]
    },
    {
      username       = "ken"
      ssh_public_key = data.vault_generic_secret.ken.data["key"]
    }
  ]
}

我只是不能创建多个用户。注意输出循环显示所有用户名。如下所示传递单个用户可以很好地工作：

data "template_cloudinit_config" "config" {
  gzip          = true
  base64_encode = true
  part {
    filename     = "cloud-init.cfg"
    content_type = "text/cloud-config"
    content = templatefile("${path.module}/templates/userdataloop.yaml", {
      username       = "fred"
      ssh_public_key = data.vault_generic_secret.fred.data["key"]
    })
  }

并使用以下模板：

#cloud-config
users:
  - default
  - name: ${username}
    gecos: ${username}
    ssh-authorized-keys:
      - ${ssh_public_key}
    lock_passwd: true
    groups: sudo
    shell: /bin/bash
}

有人能帮我吗？我只是不知道哪里出了问题，代码失败了，所以没有错误消息指向我。这是一个debian映像，代码用于虚拟机。谢谢。
