$ terraform -v
Terraform v0.12.6
provider.aws v2.23.0
provider.null v2.1.2
因此,我已将问题减少到我什至无法使用 null_resource 为超过 2 个 Windows EC2 实例运行一个 remote-exec 配置程序的程度。
用于重现错误消息的 Terraform 模板:
//VARIABLES

最佳答案
更新 :最终的诀窍是将 Terraform 降级到 v11.14
按照这个 issue comment .
您可以尝试以下几点:
remote-exec
:resource "aws_instance" "ec2instance" {
count = "${var.instance_count}"
# ...
provisioner "remote-exec" {
connection {
# ...
}
inline = [
# ...
]
}
}
现在您可以引用
self
内connection
块以获取实例的私有(private) IP。triggers
至 null_resource
:resource "null_resource" "nullresource" {
triggers {
host = "${element(aws_instance.ec2instance.*.private_ip, count.index)}" # Rerun when IP changes
version = "${timestamp()}" # ...or rerun every time
}
# ...
}
您可以使用
triggers
attribute重新创建 null_resource
并因此重新执行 remote-exec
.
关于使用 remote-exec 配置器时,当 instance_count 大于 2 时,Terraform 卡住,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/57368506/
