如何创建亚马逊网络服务安全组并在不同的.tf文件中使用？

provider "aws" {
  region = "us-west-2"
}

resource "aws_security_group" "example" {
  name        = "example-security-group"
  description = "Example security group"
  vpc_id      = aws_vpc.example.id

  ingress {
    from_port   = 80
    to_port     = 80
    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" "example" {
  ami           = "ami-0c94855ba95c71c99"
  instance_type = "t2.micro"

  vpc_security_group_ids = [aws_security_group.example.id]

  # 其他配置项...
}

resource "aws_instance" "example" {
  # 其他配置项...

  vpc_security_group_ids = [aws_security_group.example.id]

  # 其他配置项...
}
