我正在尝试使用aws_network_interface创建一个AWS实例,如下所示:

resource "aws_network_interface" "lustre-mds01" {
  subnet_id   = "${var.subnet_id}"
  private_ips = ["10.1.0.10"] 
}

resource "aws_instance" "lustre-mds01" {
  ami                    = "${var.ec2_ami}"
  instance_type          = "t2.nano"
  key_name               = "${var.key_name}"
  vpc_security_group_ids = [ "${var.vpc_security_group_id}" ]

  root_block_device {
    volume_type = "gp2"
    volume_size = 128
  }

  network_interface {
    network_interface_id = "${aws_network_interface.lustre-mds01.id}"
    device_index         = 0
  }
}

但是,结果是:

  

错误:“ network_interface”:与vpc_security_group_ids冲突

看来这是有问题的,但是票证由于不活动而被关闭。我是terraform菜鸟,所以不知道这是bug还是用户错误。

我的环境:

$ terraform -v
Terraform v0.12.2
+ provider.aws v2.15.0
+ provider.external v1.1.2
+ provider.local v1.2.2
+ provider.null v2.1.2

aws_network_interface resource允许您为接口设置安全组(安全组受ENI限制,因此这很有意义),因此,如果定义network_interface块,则将覆盖默认值ENI因此无法在实例级别指定安全组。

因此,在您的情况下,您可能想要以下内容:

resource "aws_network_interface" "lustre-mds01" {
  subnet_id       = "${var.subnet_id}"
  private_ips     = ["10.1.0.10"]
  security_groups = ["${var.vpc_security_group_id}"] 
}

resource "aws_instance" "lustre-mds01" {
  ami           = "${var.ec2_ami}"
  instance_type = "t2.nano"
  key_name      = "${var.key_name}"

  root_block_device {
    volume_type = "gp2"
    volume_size = 128
  }

  network_interface {
    network_interface_id = "${aws_network_interface.lustre-mds01.id}"
    device_index         = 0
  }
}

但是,我会问为什么,因为要在aws_instance resource中直接设置实例的私有IP地址要简单得多,所以这里要替换默认的ENI:

resource "aws_instance" "lustre-mds01" {
  ami                    = "${var.ec2_ami}"
  instance_type          = "t2.nano"
  key_name               = "${var.key_name}"
  subnet_id              = "${var.subnet_id}"
  private_ip             = "10.1.0.10"
  vpc_security_group_ids = ["${var.vpc_security_group_id}"]

  root_block_device {
    volume_type = "gp2"
    volume_size = 128
  }
}

使用数据源来选择security groupAMI而不是传递不透明的ID可能也会使您受益。这使他们可以进行更多自我记录。
