If Then Else in Terraform For AWS Availability Zones Config

Question

需要一种基于哪个环境获取可用性区域的方法：

如果env＝sbx，则availability_；us-east-1b"us-east-1c"us-east-1d"；

elseif-env=dev然后availability_rones="；us-east-1a"us-east-1b"us-east-1d"；

else availability_ zones＝"；us-east-1a"us-east-1b"us-east-1c"；

resource "aws_rds_cluster" "example_app_postgre" { availability_zones = ????? }

Answer 1

您可能希望将map与lookup函数一起使用：

locals {
azs = {
sbx = ["us-east-1b", "us-east-1c", "us-east-1d"]
dev = ["us-east-1a", "us-east-1b", "us-east-1d"]
}
}
variable "env" {
}
resource "aws_rds_cluster" "example_app_postgre" {
availability_zones = lookup(local.azs, var.env, ["us-east-1a", "us-east-1b", "us-east-1c"])
}

您可以为变量env提供sbx、dev或任何其他内容。如果env的值不在azs的map中，则lookup函数将返回默认值。
