Question

我正在编写一个terraform模块来创建具有多个别名的单个实体。我无法查找别名身份验证后端。我错过了什么吗？任何帮助都将不胜感激。

data "vault_auth_backend" "b" {
  provider = vault.this
  for_each = {
    for alias in var.entity.aliases :
    alias.type => alias
  }
  path = each.value.auth_path
}

resource "vault_identity_entity_alias" "alias" {
  provider = vault.this

  for_each = {
    for alias in var.entity.aliases :
    alias.name => alias
  }

  name           = each.key
  mount_accessor = lookup(data.vault_auth_backend.b[each.key], "accessor", null)
  canonical_id   = vault_identity_entity.entity.id
}

Terraform Plan输出：

Error: Invalid index

  on .terraform/modules/vault_dba_entity/main.tf line 31, in resource "vault_identity_entity_alias" "alias":
  31:   mount_accessor = lookup(data.vault_auth_backend.b[each.key], "accessor", null)
    |----------------
    | data.vault_auth_backend.b is object with 2 attributes
    | each.key is "ldap-team-foo"

The given key does not identify an element in this collection value.

Answer 1

您的for_each块是不同的：在vault_auth_backend中，您使用别名的type作为密钥，而在vault_identity_entity_alias中，您使用的是别名name。然后，您尝试使用该名称在vault_auth_backend中查找，因为该名称使用type作为其密钥，所以该名称将无效。

将vault_auth_backend更改为使用alias.name => alias而不是alias.type => alias。

多个Vault身份验证后端上的数据查找无效索引
