基于地图查找的var地形插值

我已使用 Terraforming 有一个巨大的文件保存着所有的安全组。

问题是,在每个安全组中都有一些规则,指的是安全组ID,它不存在于新区域中,我计划在。例如:

resource "aws_security_group" "my-group" {
    name        = "my-group"
    description = ""
    vpc_id      = "${var.vpc["production"]}"

    ingress {
        from_port       = 80
        to_port         = 80
        protocol        = "tcp"
        security_groups = ["sg-25bee542"] <-- this ID doesnt exists in the new region i'm planning to work on
        self            = false
    }

我已经创建了一个包含所有旧安全组的映射:

variable "security_groups" {
    type    = "map"
    default = {
        "sg-acd22fdb" = "default"
        "sg-52cd3025" = "my-group"
        "sg-25bee542" = "my-group2"
        ...
    }
}

现在我正试图解决这个硬编码 sg-*id* 将其插入到相应的安全组名中,以便第一个示例可以这样工作:

resource "aws_security_group" "my-group" {
    name        = "my-group"
    description = ""
    vpc_id      = "${var.vpc["production"]}"

    ingress {
        from_port       = 80
        to_port         = 80
        protocol        = "tcp"
        security_groups = ["${aws_security_group.my-group2.id}"] <-- the 'my-group2' should be resolved from the map variable
        self            = false
    }

类似于:

resource "aws_security_group" "my-group" {
    name        = "my-group"
    description = ""
    vpc_id      = "${var.vpc["production"]}"

    ingress {
        from_port       = 80
        to_port         = 80
        protocol        = "tcp"
        security_groups = ["${aws_security_group.[lookup(security_groups,sg-25bee542]].id}"] <-- the 'my-group2' string should be resolved from the map variable by looking its sg ID
        self            = false
    }

我希望我在这个问题上说清楚了…有什么想法吗?
