EC2。负载平衡器。必须至少指定两个子网

AWS文档中没有具体的示例,但一定要首先了解专有网络的概念和子网的创建。看到了吗 Scenarios and Examples

配置ELB时选择子网现在应该很简单了。

一 b . 地形配置的相关部分_名称.tf会像这样:

setting {
    namespace = "aws:ec2:vpc"
    name      = "Subnets"
    value     = "${lookup(var.vpc_subnets, format("%s_%s", var.location, var.availability_zone))}, ${lookup(var.vpc_subnets, format("%s_%s", var.location, var.secondary_availability_zone))}"
}

variable "vpc_subnets" {
  type = "map"
  default = {
    "frankfurt_a" = "subnet-12345671"
    "frankfurt_b" = "subnet-12345672"
    "frankfurt_c" = "subnet-12345673"
    "ireland_a" = "subnet-12345674"
    "ireland_b" = "subnet-12345675"
    "ireland_c" = "subnet-12345676"
  }
}

variable "availability_zone" {
  default = "a"
}

variable "secondary_availability_zone" {
  default = "b"
}


variable "regions" {
  type = "map"
  default = {
    "frankfurt" = "eu-central-1"
    "ireland" = "eu-west-1"
    "london" = "eu-west-2"
  }
}

variable "location" {
  default = "ireland"
}
