Вы можете посмотреть, используя aws_security_group_rule
вместо того, чтобы встроить свои правилаЗатем вы можете создать такой модуль:
module / sg / sg.tf
resource "aws_security_group" "default" {
name = "${var.security_group_name}"
description = "${var.security_group_name} group managed by Terraform"
vpc_id = "${var.vpc_id}"
}
resource "aws_security_group_rule" "egress" {
type = "egress"
from_port = 0
to_port = 0
protocol = "-1"
cidr_blocks = ["0.0.0.0/0"]
description = "All egress traffic"
security_group_id = "${aws_security_group.default.id}"
}
resource "aws_security_group_rule" "tcp" {
count = "${var.tcp_ports == "default_null" ? 0 : length(split(",", var.tcp_ports))}"
type = "ingress"
from_port = "${element(split(",", var.tcp_ports), count.index)}"
to_port = "${element(split(",", var.tcp_ports), count.index)}"
protocol = "tcp"
cidr_blocks = ["${var.cidrs}"]
description = ""
security_group_id = "${aws_security_group.default.id}"
}
resource "aws_security_group_rule" "udp" {
count = "${var.udp_ports == "default_null" ? 0 : length(split(",", var.udp_ports))}"
type = "ingress"
from_port = "${element(split(",", var.udp_ports), count.index)}"
to_port = "${element(split(",", var.udp_ports), count.index)}"
protocol = "udp"
cidr_blocks = ["${var.cidrs}"]
description = ""
security_group_id = "${aws_security_group.default.id}"
}
modules / sg / variables.tf
variable "tcp_ports" {
default = "default_null"
}
variable "udp_ports" {
default = "default_null"
}
variable "cidrs" {
type = "list"
}
variable "security_group_name" {}
variable "vpc_id" {}
Использовать модульв вашем main.tf
module "sg1" {
source = "modules/sg"
tcp_ports = "22,80,443"
cidrs = ["10.0.0.5/32", "10.0.0.50/32", "10.0.0.200/32"]
security_group_name = "SomeGroup"
vpc_id = "${aws_vpc.this_vpc.id}"
}
module "sg2" {
source = "modules/sg"
tcp_ports = "22,80,443"
cidrs = ["10.0.0.5/32", "10.0.0.50/32", "10.0.0.200/32"]
security_group_name = "SomeOtherGroup"
vpc_id = "${aws_vpc.this_vpc.id}"
}
Ссылки:
Почему необязательное исключение ресурса с количеством выглядит следующим образом ( source ):
count = "${var.udp_ports == "default_null" ? 0 : length(split(",", var.udp_ports))}"
И переменная установлена на:
variable "udp_ports" {
default = "default_null"
}
