根因分析

同一模块中存在两个或更多具有相同资源类型和名称的资源块，导致重复定义。

English

Two or more resource blocks with the same resource type and name exist within the same module, causing a duplicate definition.

解决方案

  1. Remove or rename one of the duplicate resource blocks in the module configuration file. For example, change `resource "aws_instance" "web"` to `resource "aws_instance" "web2"` and update references.
  2. Use a single resource block with count or for_each if multiple instances are needed: `resource "aws_instance" "web" { count = 2 ... }`

无效尝试

常见但无效的做法:

  1. Add count or for_each to the duplicate resource block 85% 失败

    Count/for_each creates multiple instances but doesn't resolve duplicate block definitions.

  2. Rename the module call in the root module 75% 失败

    The duplicate is within the same module, not at the call site.

  3. Delete the .terraform directory and re-run init 90% 失败

    The config file itself has duplicates; init doesn't fix config errors.
