我有这个很好用的脚本。它创建了 3 个带有 sepcified 标签的实例以轻松识别它们。但问题是我想在代码中添加一个 remote-exec 配置程序（当前已注释）以安装一些软件包。如果我使用的是计数，我可以循环遍历它以对所有实例执行远程执行。我不能使用 count 因为我必须使用 for_each 来循环本地列表。由于 count 和 for_each 不能一起使用，我如何遍历实例以检索它们的 IP 地址以在 remote-exec 配置器中使用。
在数字海洋和 AWS 上，我能够使用 host = "${self.public_ip}"
但它不适用于 vultr 并给出 Unsupported attribute 错误
