Terraform 地形-展平嵌套地图

我目前有一个terraform对象声明如下：

locals {
    x = {
        a = [
            {
                p0 = "j"
                p1 = "test-1"
                p2 = 0
            },
            {
                p0 = "k"
                p1 = "test-2"
                p2 = 0
            }
        ]
        b = [
            {
                p0 = "j"
                p1 = "test-1"
                p2 = 1
            },
            {
                p0 = "k"
                p1 = "test-3"
                p2 = 0
            }
        ]   
    }
}

locals {
    y = {
        a-j {
            p0 = "j"
            p1 = "test-1"
            p2 = 0
        }
        a-k {
            p0 = "k"
            p1 = "test-2"
            p2 = 0
        }
        b-j {
            p0 = "j"
            p1 = "test-1"
            p2 = 1
        }
        b-k {
            p0 = "k"
            p1 = "test-3"
            p2 = 0
        }
    }
}

我想做的是使结构变平，但我不知道这在地形中是否可行。在我的例子中，我知道p0在它自己的数组中是唯一的，所以我应该能够为每个记录构造唯一的键。我期望的输出如下：

locals {
    x = {
        a = [
            {
                p0 = "j"
                p1 = "test-1"
                p2 = 0
            },
            {
                p0 = "k"
                p1 = "test-2"
                p2 = 0
            }
        ]
        b = [
            {
                p0 = "j"
                p1 = "test-1"
                p2 = 1
            },
            {
                p0 = "k"
                p1 = "test-3"
                p2 = 0
            }
        ]   
    }
}

locals {
    y = {
        a-j {
            p0 = "j"
            p1 = "test-1"
            p2 = 0
        }
        a-k {
            p0 = "k"
            p1 = "test-2"
            p2 = 0
        }
        b-j {
            p0 = "j"
            p1 = "test-1"
            p2 = 1
        }
        b-k {
            p0 = "k"
            p1 = "test-3"
            p2 = 0
        }
    }
}

我通过将所有内容转换为列表、将其展平并使用count来实现这一点，但我希望保留这些键，以防以后顺序发生变化，从而防止不必要地删除资源。谢谢你的帮助

我认为以下几点应该满足您的要求：

locals {

    x = {
        a = [
            {
                p0 = "j"
                p1 = "test-1"
                p2 = 0
            },
            {
                p0 = "k"
                p1 = "test-2"
                p2 = 0
            }
        ]
        b = [
            {
                p0 = "j"
                p1 = "test-1"
                p2 = 1
            },
            {
                p0 = "k"
                p1 = "test-3"
                p2 = 0
            }
        ]   
    }
    
    flat = merge([
        for k1, v1 in local.x:
        {
          for  v2 in v1: 
            "${k1}-${v2.p0}" => v2
        }
      ]...)  
    
}

这将导致

flat

为：

{
  "a-j" = {
    "p0" = "j"
    "p1" = "test-1"
    "p2" = 0
  }
  "a-k" = {
    "p0" = "k"
    "p1" = "test-2"
    "p2" = 0
  }
  "b-j" = {
    "p0" = "j"
    "p1" = "test-1"
    "p2" = 1
  }
  "b-k" = {
    "p0" = "k"
    "p1" = "test-3"
    "p2" = 0
  }
}

太好了，谢谢你的帮助
