使用 terraform 启动 EC2 实例时出错

Question

我对 Terraform 还很陌生。我正在尝试使用以下 Terraform 代码来启动 EC2 实例：

provider "aws" {
  region     = "ap-south-1"
  access_key = "<Key>"
  secret_key = "<secret>"
}
# Main VPC
resource "aws_vpc" "vpc_main" {
  cidr_block = "10.0.0.0/16"

  enable_dns_support   = true
  enable_dns_hostnames = true

  tags = {
    Name = "Main VPC"
  }
}

resource "aws_subnet" "public" {
  vpc_id                  = "${aws_vpc.vpc_main.id}"
  cidr_block              = "10.0.0.0/16"
  map_public_ip_on_launch = true
  tags = {
    Name                  = "Public Subnet"
  }
}

resource "aws_security_group" "allow_web" {
  name        = "allow-web-traffic"
  description = "Allow all inbound/outbound traffic on 80 443"
  vpc_id      = "${aws_vpc.vpc_main.id}"

  ingress {
    from_port   = 80
    to_port     = 80
    protocol    = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }

  ingress {
    from_port = 443
    to_port   = 443
    protocol  = "tcp"
  }

  egress {
    from_port   = 0
    to_port     = 0
    protocol    = "-1"
    cidr_blocks = ["0.0.0.0/0"]
  }
}

resource "aws_security_group" "allow_ssh" {
  name        = "allow-ssh-traffic"
  description = "Allow ssh traffic on 22"
  vpc_id      = "${aws_vpc.vpc_main.id}"

  ingress {
    from_port   = 22
    to_port     = 22
    protocol    = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }

  egress {
    from_port   = 0
    to_port     = 0
    protocol    = "-1"
    cidr_blocks = ["0.0.0.0/0"]
  }
}

resource "aws_instance" "proxy_server" {
  ami           = "ami-026f33d38b6410e30" # RHEL 7.5 HVM SSD
  instance_type = "t2.micro"
  key_name      = "EC2NewKey"
  security_groups = ["allow_ssh","allow_web"]
  vpc_security_group_ids = ["${aws_security_groups.allow_ssh.id}","${aws_security_group.allow_web.id}"] # this breaks it
  subnet_id     = "${aws_subnet.public.id}"
}

但在执行“Terraform plan”时出错：“未在根模块中声明托管资源“aws_security_groups”“allow_ssh”。谁能告诉我我在代码中犯了什么基本错误 ?

一个错字。

aws_security_groups.allow_ssh.id

应该变成：

aws_security_group.allow_ssh.id
