Create multiple rules in AWS security Group

Hi,

I tried to create an AWS security group with multiple inbound rules, Normally we need to multiple ingresses in the sg for multiple inbound rules. Instead of creating multiple ingress rules separately, I tried to create a list of ingress and so that I can easily reuse the module for different applications.

PFB,

module/sg/sg.tf >>

resource "aws_security_group" "ec2_security_groups" {
  name   = var.name_security_groups
  vpc_id = var.vpc_id
}

module/sg/rules.tf >>

resource "aws_security_group_rule" "ingress_rules" {
  count             = lenght(var.ingress_rules)
  type              = "ingress"
  from_port         = var.ingress_rules[count.index][0]
  to_port           = var.ingress_rules[count.index][1]
  protocol          = var.ingress_rules[count.index][2]
  cidr_blocks       = var.ingress_rules[count.index][3]
  description       = var.ingress_rules[count.index][4]
  security_group_id = aws_security_group.ec2_security_groups.id
}

module/sg/variable.tf >>

variable "vpc_id" {
}
variable "name_security_groups" {
}
variable "ingress_rules" {
    type = list(string)
}

In the application folder,

application/dev/sg.tf >>

module "sg_test" {
  source = "../modules/sg"

  vpc_id                   = "vpc-xxxxxxxxx"
  name_security_groups = "sg_test"
  ingress_rules                     = var.sg_ingress_rules 
}

application/dev/variable.tf >>

variable "sg_ingress_rules" {
    type        = list(string)
    default     = {
        [22, 22, "tcp", "1.2.3.4/32", "test"]
        [23, 23, "tcp", "1.2.3.4/32", "test"]
    }
}

Please help to correct this or if there is any other method please suggest.
