terraform - terraform>在安全组上强制使用新资源

我有一段非常简单的Terraform代码:

provider "aws" {
  region = "eu-west-1"
}

module ec2 {
  source = "./ec2_instance"
  name = "EC2 Instance 1"
}

模块在哪里:

variable "name" {
    default = "Default Name from ec2_instance.tf"
}

resource "aws_instance" "example" {
  ami = "ami-e5083683"
  instance_type = "t2.nano"
  subnet_id = "subnet-3e976259"
  associate_public_ip_address = true
  security_groups = [ "sg-7310e10b" ]
  tags {
    Name = "${var.name}"
  }
}

当我第一次运行它时，我得到以下输出:

security_groups.#:            "" => "1"
security_groups.1642973399:   "" => "sg-7310e10b"

但是，下次我尝试plan时，我得到:

  security_groups.#:            "0" => "1" (forces new resource)
  security_groups.1642973399:   "" => "sg-7310e10b" (forces new resource)

是什么赋予了？!

最佳答案

您错误地将 vpc_security_group_id 分配给 security_groups 而不是 vpc_security_group_ids 。将 security_groups = [“sg-7310e10b”] 更改为 vpc_security_group_ids = [“sg-7310e10b”] ，一切正常。
