Terraform - AWS 上的共享卷

Question

正在尝试将共享卷附加到我的自动缩放组。不确定如何在terraform中完成这项工作，或者即使有可能？

aws_volume_attachment采用一个实例 ID，但我希望以某种方式将其放入启动配置中。有人可以帮忙吗？

resource "aws_ebs_volume" "shared_volume" {
availability_zone = "us-east-1"
size = 2
}
resource "aws_volume_attachment" "volume_attachment" {
device_name = "/dev/xvdb"
instance_id = "????"
volume_id = "${aws_ebs_volume.shared_volume.id}"
skip_destroy = true
}
resource "aws_launch_configuration" "flume-conf" {
image_id             = "${var.app_ami_id}"
instance_type        = "${var.app_instance_type}"
key_name             = "${var.ssh_key_name}"
security_groups      = ["${var.app_security_group_id}"]
user_data            = "${data.template_file.config.rendered}"
iam_instance_profile = "${var.app_iam_role}"
root_block_device {
volume_size = 50
volume_type = "gp2"
}
lifecycle {
create_before_destroy = true
}
}
resource "aws_autoscaling_group" "ec2_asg" {
name                 = "${format("%s", var.app_name)}"
launch_configuration = "${aws_launch_configuration.flume-conf.name}"
min_size             = "${var.asg_min_size}"
max_size             = "${var.asg_max_size}"
vpc_zone_identifier  = ["${element(data.aws_subnet_ids.private.ids, 0)}", "${element(data.aws_subnet_ids.private.ids, 1)}"]
availability_zones   = "${var.availability_zones}"
depends_on = []
lifecycle {
create_before_destroy = false
}
}

EBS 卷无法挂载到多个主机。如果您正在寻找此功能，请考虑 EFS。
