将所有DigitalOcean水滴实例添加到Terraform中的项目中

我正在尝试循环DigitalOcean Droplet中的所有实例，其中有未知数量的实例要添加到DigitalOcean项目中

类似于下面的内容，但不知道如何

resource "digitalocean_droplet" "web" {
  count = var.droplet_count 
  name = "web-${var.name}-${var.region}-${count.index +1}"
  size   = "512mb"
  image  = "centos-7-x64"
  region = "nyc3"


}

resource "digitalocean_project_resources" "barfoo" {
  project = data.digitalocean_project.foo.id
  resources = [
     digitalocean_droplet.web.*.urn, # this part having issues with
     digitalocean_droplet.bastion.urn,
  ]
}

---

资源-与项目关联的资源的统一资源名称（URN）列表

试一试

resources = flatten([digitalocean_droplet.web.*.urn, digitalocean_droplet.bastion.urn])
