地形>强制安全组上的新资源 [英] terraform > forces new resource on security group

问题描述

我有一段非常简单的 Terraform 代码:​​

I've got a very simple piece of Terraform code:

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，我得到这个输出:

When I first run it I get this output:

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

但是，下次我尝试 plan 时，我得到:

However, the next time I try a plan I get:

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

什么给了?！

推荐答案

您错误地将 vpc_security_group_id 分配到 security_groups 而不是 vpc_security_group_ids.将
security_groups = [ "sg-7310e10b" ]
更改为
vpc_security_group_ids = [ "sg-7310e10b" ] 一切都会好起来的.

You are incorrectly assigning a vpc_security_group_id into security_groups instead of into vpc_security_group_ids. Change
security_groups = [ "sg-7310e10b" ]
to
vpc_security_group_ids = [ "sg-7310e10b" ] and everything will be ok.
