如何在Terraform中转换嵌套数组

Question

如何使用map检索嵌套数组？我想把要注册的记录从本地传递到Route53。

示例

locals {
cname = {
"bbb.example.io" = {
records = ["example"]
}
"aaa.example.io" = {
records = [
"example1",
"example2",
"example3"
]
}
}
}
resource "aws_route53_record" "cname" {
for_each = local.cname
name     = each.key
records  = [] ←Problem areas
ttl      = 300
type     = "CNAME"
zone_id  = aws_route53_zone.example.zone_id
}

Answer 1

给定您在本例中设置for_each的方式，该块中的each.value将是local.cname映射中的相应对象，因此您可以以通常的方式访问该对象的records属性：

resource "aws_route53_record" "cname" {
for_each = local.cname
name     = each.key
records  = each.value.records
ttl      = 300
type     = "CNAME"
zone_id  = aws_route53_zone.example.zone_id
}
