我有以下资源来创建2个实例:
`resource "aws_instance" "prod_server" {
count = "${var.instance_count}"
instance_type = "${var.instance_type}"
ami = "${data.aws_ami.server_ami.id}"
key_name = "${aws_key_pair.prod_auth.id}"
vpc_security_group_ids = ["${var.vpc_security_group}"]
subnet_id = "${element(var.subnets, count.index)}"
user_data = "${data.template_file.user-init.*.rendered[count.index]}"
tags {
Name = "prod_server-${count.index+1}"
}
}`
其中count的值为2。
我想使用单独的输出资源为每个实例输出实例ID,如下所示:
`output "server_id1" {
value = "${aws_instance.prod_server.0.id}"
}
output "server_id2" {
value = "${aws_instance.prod_server.1.id}"
}`
但是我一直收到以下错误:
Resource 'aws_instance.prod_server' not found for variable 'aws_instance.prod_server.1.id'
我意识到我可以使用以下方法立即获取ID:
"${aws_instance.prod_server.*.id}"
但我确实有一个特定的理由想要逐一获得它们。
有人可以建议/帮我解决这个问题吗?

您可以像这样使用element
:
<div id="left-pane">
<div id="top-image" class="img-wrapper">
<div class="img visible" data-imageset="1"
style="background-image: url('http://placeimg.com/640/480/people');">
</div>
<div class="img" data-imageset="2"
style="background-image: url('http://placeimg.com/640/480/animals');">
</div>
<div class="img" data-imageset="3"
style="background-image: url('http://placeimg.com/640/480/any');">
</div>
</div>
<div id="bottom-image" class="img-wrapper">
<div class="img visible" data-imageset="1"
style="background-image: url('http://placeimg.com/640/480/nature');">
</div>
<div class="img" data-imageset="2"
style="background-image: url('http://placeimg.com/640/480/tech');">
