Error: Invalid index

  on .terraform/modules/database-security-group/main.tf line 70, in resource "aws_security_group_rule" "ingress_rules":
  70:   to_port   = var.rules[var.ingress_rules[count.index]][1]
    |----------------
    | count.index is 0
    | var.ingress_rules is list of string with 1 element
    | var.rules is map of list of string with 119 elements

给定的键不标识此集合值中的元素。

我对此一窍不通。我们需要帮助..。

module "database-security-group" {
  source = "terraform-aws-modules/security-group/aws"
  name        = "database-security"
  description = "Security group for Database on database subnet."
  vpc_id      = module.vpc.vpc_id
  ingress_cidr_blocks = ["0.0.0.0/0"]
  ingress_rules       = [ "http-3306-tcp"]
  egress_rules        = ["all-all"]
  tags = {
    Name        = "Database"
    Environment = "spoon"
  }
}

Answer 1

我相信这个特定模块的目的是在指定它的预定义规则表和egress_rules时从egress_rules中进行选择。

在我写这篇文章时，我还没有看到规则"http-3306-tcp"的定义，所以我认为这是导致错误的原因。如果您的意图是允许TCP端口3306用于MySQL，那么它的规则关键似乎是"mysql-tcp"。
