[英]How to iterate over list(string) and append to same records Terraform
[英]Terraform - iterate over combined map and list
我想使用 Terraform 将列表和 map 组合成 AWS 安全组的一组资源 arguments。 对于端口列表中的每个端口,以及 map 人中的每个密钥,我希望在安全组中有一个 Ingress 规则。 因此,例如我有一个 (simplified).tf 像这样(我不知道的问号):
variable "IP_Mapping" {
type = "map"
default = {
"bob" = "1.1.1.1/32"
"alice" = "2.2.2.2/32"
}
}
variable "ingress_ports" {
type = list(number)
description = "list of ingress ports"
default = [80, 443]
}
resource "aws_security_group" "sg-vpc" {
name = "sd-ocp-vpc_sg"
description = "Default security group"
vpc_id = "${aws_vpc.vpc.id}"
ingress {
from_port = ?
to_port = ?
protocol = "tcp"
cidr_blocks = ?
description = ?
}
}
我想要这样的 static 资源:
resource "aws_security_group" "sg-vpc" {
name = "sd-ocp-vpc_sg"
description = "Default security group"
vpc_id = "${aws_vpc.vpc.id}"
ingress {
from_port = 80
to_port = 80
protocol = "tcp"
cidr_blocks = ["1.1.1.1/32"]
description = "bob"
}
ingress {
from_port = 443
to_port = 443
protocol = "tcp"
cidr_blocks = ["1.1.1.1/32"]
description = "bob"
}
ingress {
from_port = 80
to_port = 80
protocol = "tcp"
cidr_blocks = ["2.2.2.2/32"]
description = "alice"
}
ingress {
from_port = 443
to_port = 443
protocol = "tcp"
cidr_blocks = ["2.2.2.2/32"]
description = "alice"
}
}
我意识到入口块的顺序并不重要。 如果我没有看到更好的方法,我也不会过度依赖地图/列表数据结构,只要我不必为每个用户列出每个端口(可能有很多端口,但它们'对所有用户来说总是一样的)。
我已经为入口规则使用动态块,并且可以弄清楚如何在动态块中迭代 map,但是我终生无法弄清楚如何在动态中获得嵌套的 for 循环工作的资源参数。
在构建动态块之前,您可以先使用setproduct并创建一个helper_list
。
locals {
helper_list = setproduct(
var.ingress_ports,
[for name, cidr in var.IP_Mapping: [name, cidr]])
}
local.helper_list
应该是这样的形式:
[
[
80,
[
"alice",
"2.2.2.2/32",
],
],
[
80,
[
"bob",
"1.1.1.1/32",
],
],
[
443,
[
"alice",
"2.2.2.2/32",
],
],
[
443,
[
"bob",
"1.1.1.1/32",
],
],
]
然后为您的动态块:
resource "aws_security_group" "sg-vpc" {
name = "sd-ocp-vpc_sg"
description = "Default security group"
vpc_id = "${aws_vpc.vpc.id}"
dynamic "ingress" {
for_each = {for idx, item in local.helper_list: idx=>item}
content {
from_port = ingress.value[0]
to_port = ingress.value[0]
protocol = "tcp"
cidr_blocks = [ingress.value[1][1]]
description = ingress.value[1][0]
}
}
}
