Hi TJ, Hope you are doing good. I have a question related to this vodeo. I am thinking of creating a variable which will contain list within list .. the list within list will contain whol info about a rule ..for ex.
variable "elb_ingress_rule" {
description = "values must be in sequence [from_port, to_port, protocol, cidr_blocks, security_group, description]"
}

elb_ingress_rule = [
[80, 80, "tcp", [0.0.0.0/0], "", "traffic from Internet on port 80"],
[443, 443, "tcp", [0.0.0.0/0], "", "traffic from Internet on port 443"]
]

But i am unable to work this out after watching your video. I tried many combination to work this out but didn't worked.

I want to gather the info about rules in a list form and then create rules. Note: I have added in index 3 (for cidr_sunets) and 4 (for subnet_groups) to define, but as you know we can't define both at the same rule .So I also need to make sure if any one of them is not available it should not throw error.

Is there a way I can do this as I unable to find that. I can see either i do via your way then I canT define description and may things like in egress if i need to give range 3000 -65000.

Could you please direct me where I can find a solution for this.

Thanks in advance..
