在带有列表的变量中带有“for each”的动态块 - Terraform

Question

我有这个资源和这个带有这个变量的动态块：

variable "services" {
  description = "Map of the Services"
  type = map(object({
    port                           = number
    uri                            = optional(string)
  }))
}

services = {

  "auth-service" = {
    port              = 3050
    uri               = "example1"
   }

"clone-service" = {
    port              = 3040
   }

}

resource "kubernetes_ingress_v1" "eks_global_ingress" {

[...]

dynamic "rule" {
     # I make this expression to bypass the services that doesn't have URI.
      for_each = { for k, v in var.services : k => v if v["uri"] != null }
      content {
        http {
          path {
            path = "/${rule.value["uri"]}/*"
            backend {
              service {
                name = "${rule.key}-i-svc"
                port {
                  number = rule.value["port"]
                }
              }
            }
          }
        }
      }
    }

此时一切正常，但现在我想为同一个服务添加另一个 URI。所以我在 URI 中做了一个列表，如下所示：

services = {
  "auth-service" = {
    port              = 3050
    uri               = ["example1","example2]
  "clone-service" = {
    port              = 3040

但是有了这个我不能在动态块中包含另一个 for_each 。我如何过滤空 URI 并同时将代码与 2 个或更多 URI 作为列表循环？

我希望该规则被重复“x”次，超过列表中存在的 URI 数量，并且如果地图上不存在 URI 值（null），则“for_each”会绕过此规则。

1. 完全可以在另一个动态块中使用更多动态块
2. 参数 http.path 也是一个list块所以你应该能够做这样的事情：

      dynamic "rule" {
     # I make this expression to bypass the services that doesn't have URI.
      for_each = { for k, v in var.services : k => v if length(v["uri"]) > 0 }
      content {
        http {
          dynamic "path" {
            for_each = toset(rule.value["uri"])
            content {
              path = "/${path.key}/*"
              backend {
                service {
                  name = "${rule.key}-i-svc"
                  port {
                    number = rule.value["port"]
                  }
                }
              }
            }
          }
        }
      }
    }

注意：不要忘记将 uri 类型从字符串更改为列表（字符串）
