How to use count with null-resource?
问题
我已经定义了一个名为null_resource的资源，如下所示：
resource "null_resource" "mynull-resource" {
triggers = {
always-update = timestamp()
}
# Connection Block for Provisioners to connect to EC2 Instance
connection {
type = "ssh"
host = aws_instance.web[count.index].public_ip #Giving error
user = "ec2-user"
password = ""
private_key = file("ec2keypair.pem")
}
}
错误信息：
The "count" object can only be used in "module", "resource", and "data" blocks, and only when the "count" argument is set.
我该如何更新connection block以连接到多个主机？
我尝试使用spat operator，但是host = aws_instance.web.*.public_ip不起作用。

Error:

How can I update the connection block to connect to multiple hosts?
I have tried using spat operator but it is not working host = aws_instance.web.*.public_ip

得分: 1
在resource下使用count：
resource "null_resource" "mynull-resource" {
count = length(aws_instance.web)
triggers = {
always-update = timestamp()
}
# Provisioners连接到EC2实例的连接块
connection {
type = "ssh"
host = aws_instance.web[count.index].public_ip #出现错误
user = "ec2-user"
password = ""
private_key = file("ec2keypair.pem")
}
}
请注意，我只提供了代码的翻译部分，不包括其他内容。
英文:
Use count under resource:
resource "null_resource" "mynull-resource" {
count = length(aws_instance.web)
triggers = {
always-update = timestamp()
}
# Connection Block for Provisioners to connect to EC2 Instance
connection {
type = "ssh"
host = aws_instance.web[count.index].public_ip #Giving error
user = "ec2-user"
password = ""
private_key = file("ec2keypair.pem")
}
