我想在资源本身内部使用一个资源名称,以避免字符串重复和复制/粘贴错误。
resource "aws_instance" "bastion-euw3-infra-01" {
ami = "ami-078db6d55a16afc82"
instance_type = "t2.micro"
key_name = "sylvain"
user_data = templatefile("./scripts/cloudinit.yaml", {
hostname = "bastion-euw3-infra-01"
tailscale_authkey = var.tailscale_authkey
})
network_interface {
device_index = 0
network_interface_id = aws_network_interface.bastion-euw3-infra-01.id
}
tags = {
Name = "bastion-euw3-infra-01"
Environment = "infra"
}
lifecycle {
ignore_changes = [user_data]
}
}
基本上,我想用某种var替换资源中的"bastion-euw3-infra-01"
,例如:
resource "aws_instance" "bastion-euw3-infra-01" {
...
user_data = templatefile("./scripts/cloudinit.yaml", {
hostname = ___name___
tailscale_authkey = var.tailscale_authkey
})
...
tags = {
Name = ___name___
Environment = "infra"
}
...
}
terraform提供了一种方法吗?
