Question

tag_name

）进入集合/列表

tag_value

以下输出中的任何一个可能对我有用：

locals {
  what_i_have = {
    "cluster=foo|instance=foo#1" = [
      {
        instance_id = "i-fff11111"
        tag_name = "tag1"
        tag_value = "val1_a"
      },
      {
        instance_id = "i-fff11111"
        tag_name = "tag1"
        tag_value = "val1_b"
      },
    ],
    "cluster=foo|instance=foo#2" = [
      {
        instance_id = "i-fff22222"
        tag_name = "tag1"
        tag_value = "val1_a"
      },
      {
        instance_id = "i-fff22222"
        tag_name = "tag1"
        tag_value = "val1_b"
      },
    ],
    "cluster=bar|instance=bar#1" = [
      {
        instance_id = "i-bbb11111"
        tag_name = "tag1"
        tag_value = "val1_a"
      },
    ],
  },
}

这是可能的吗？

i天真地试图看看它的作用（下面

locals {
  what_i_want_v1 = {
    "cluster=foo|instance=foo#1" = {
      instance_id = "i-fff11111"
      tag_name = "tag1"
      tag_value = ["val1_a", "val1_b"] # Values for identical `what_i_have` key are now "merged" in a set/list
    },
    "cluster=foo|instance=foo#2" = {
      instance_id = "i-fff22222"
      tag_name = "tag1"
      tag_value = ["val1_a", "val1_b"]
    },
    "cluster=bar|instance=bar#1" = {
      instance_id = "i-bbb11111"
      tag_name = "tag1"
      tag_value = ["val1_a"]
    },
  },

  what_i_want_v2 = [ # Not a map anymore but I don't mind
    {
      instance_id = "i-fff11111"
      tag_name = "tag1"
      tag_value = ["val1_a", "val1_b"]
    },
    {
      instance_id = "i-fff22222"
      tag_name = "tag1"
      tag_value = ["val1_a", "val1_b"]
    },
    {
      instance_id = "i-bbb11111"
      tag_name = "tag1"
      tag_value = ["val1_a"]
    },
  ],

  what_i_want_v3 = [
    {
      instance_id = "i-fff11111"
      tag_name = "tag1"
      tag_value = "val1_a+val1_b" # Not an set/list but a string with a "+" separator
    },
    {
      instance_id = "i-fff22222"
      tag_name = "tag1"
      tag_value = "val1_a+val1_b"
    },
    {
      instance_id = "i-bbb11111"
      tag_name = "tag1"
      tag_value = "val1_a"
    },
  ],
}

）：merge()

但（显然）吞咽值：local.attempt_1

Context：我正在将

locals {
 attempt_1 = {for k, v in local.what_i_have: k => merge(v...)}
}

构建为

# attempt_1 =
{
  "cluster=bar|instance=bar#1" = {
    instance_id = "i-bbb11111"
    tag_name    = "tag1"
    tag_value   = "val1_a"
  }
  "cluster=foo|instance=foo#1" = {
    instance_id = "i-fff11111"
    tag_name    = "tag1"
    tag_value   = "val1_b"
  }
  "cluster=foo|instance=foo#2" = {
    instance_id = "i-fff22222"
    tag_name    = "tag1"
    tag_value   = "val1_b"
  }
}

资源，以从标签列表中标记实例。
    

您可以将价值弄平，然后在它们上迭代：

what_i_have

for_each
