EC2 实例创建 [英] EC2 instance creation

问题描述

我正在尝试创建多个 EC2 实例，但它们具有不同的 AMI、实例类型，并且应该位于不同的可用区中，如下所示.我尝试了几种不同的方法，但都无法成功.

I'm trying to create multiple EC2 instance but they have different AMIs, instance types and should be in different availability zones as shown below. I've tried a few different ways but can't make it work.

locals {
  az_ami = [
    {Name = "host1", type = "t3a.medium", az = "eu_west_2a", ami_id = "ami-01234abc"},
    {Name = "host2", type = "t3a.micro", az = "eu_west_2b", ami_id = "ami-01234def"},
    {Name = "host3", type = "t3a.medium", az = "eu_west_2b", ami_id = "ami-01234gef"},
    {Name = "host4", type = "t3a.medium", az = "eu_west_2a", ami_id = "ami-01234hty"}
  ]
}

#variable "ami_id" {}

resource "aws_instance" "myinstance" {
  count    = length(local.az_ami)
  for_each = [{ for i in local.az_ami: }]

  dynamic "ec2_instance"{
    for_each = local.az_ami[count.index]
    content {
      instance_type     = "ec2_instance.value.Name"
      availability_zone = "ec2_instance.value.az"
      ami               = "ec2_instance.value.ami_id"
    }
  }
}

推荐答案

如果要使用count，那么应该是:

If you want to use count, then it should be:

resource "aws_instance" "myinstance" {

  count             = length(local.az_ami)

  instance_type     = local.az_ami[count.index].type
  availability_zone = local.az_ami[count.index].az
  ami               = local.az_ami[count.index].ami_id
  
  tags = {
    Name = local.az_ami[count.index].Name
  }
}

但使用 for_each 可能是:

resource "aws_instance" "myinstance2" {

  for_each    = {for idx, val in local.az_ami: idx => val}

  instance_type     = each.value.type
  availability_zone = each.value.az
  ami               = each.value.ami_id
  
  tags = {
    Name = each.value.Name
  }
}
