使用具有嵌套for循环的terraform的安全组

resource "aws_security_group" "example" {
  name        = "example"
  description = "Example security group"

  // 入站规则
  dynamic "ingress" {
    for_each = var.inbound_rules
    content {
      from_port   = ingress.value.from_port
      to_port     = ingress.value.to_port
      protocol    = ingress.value.protocol
      cidr_blocks = [ingress.value.cidr_block]
    }
  }

  // 出站规则
  dynamic "egress" {
    for_each = var.outbound_rules
    content {
      from_port   = egress.value.from_port
      to_port     = egress.value.to_port
      protocol    = egress.value.protocol
      cidr_blocks = [egress.value.cidr_block]
    }
  }
