Question

是否有添加条件来选择资源本身

如果env = dev

，我需要以下资源

resource "aws_rds_cluster" "myDB" {
  cluster_identifier      = "aurora-cluster-demo"
  engine                  = "aurora-mysql"
  engine_version          = "5.7.mysql_aurora.2.03.2"
  availability_zones      = ["us-west-2a", "us-west-2b", "us-west-2c"]
  database_name           = "mydb"
  master_username         = "foo"
  master_password         = "bar"
  backup_retention_period = 5
  preferred_backup_window = "07:00-09:00"
}

 resource "route53" "dns" {
 }

其他低于资源

resource "aws_rds_cluster" "myDB" {
  cluster_identifier      = "aurora-cluster-demo"
  engine                  = "aurora-postgres"
  engine_version          = "5.7.mysql_aurora.2.03.2" 
  database_name           = "mydb"
  master_username         = "foo"
  master_password         = "bar" 
  preferred_backup_window = "07:00-09:00"
}

我可以开始如下所示添加所有变量，或创建局部变量。 engine = var.env = dev？“ aurora-mysql”：“ aurora-postgres”

还有其他方法可以禁用资源本身吗？

也许在count的帮助下，类似的事情也应该起作用


resource "aws_rds_cluster" "myDB-mysql" {
  count                   = var.env == dev ? 1 : 0
  cluster_identifier      = "aurora-cluster-demo"
  engine                  = "aurora-mysql"
  engine_version          = "5.7.mysql_aurora.2.03.2"
  availability_zones      = ["us-west-2a", "us-west-2b", "us-west-2c"]
  database_name           = "mydb"
  master_username         = "foo"
  master_password         = "bar"
  backup_retention_period = 5
  preferred_backup_window = "07:00-09:00"
}

resource "aws_rds_cluster" "myDB-postgres" {
  count                   = var.env != dev ? 1 : 0
  cluster_identifier      = "aurora-cluster-demo"
  engine                  = "aurora-postgres"
  engine_version          = "5.7.mysql_aurora.2.03.2" 
  database_name           = "mydb"
  master_username         = "foo"
  master_password         = "bar" 
  preferred_backup_window = "07:00-09:00"
}
