terraform查找问题 [英] Issue with terraform lookup

问题描述

这是我运行Terraform Plan时得到的，它以前可以在以前的版本中运行，所以基本上concat返回的是列表而不是字符串.

This is what I'm getting when I run terraform plan, It used to work earlier with previous version, So basically concat is returning list instead of string.

Errors:

* At column 3, line 1: lookup: argument 2 should be type string, got type list in:

${lookup(var.az, concat("zone", count.index + 1))}

我正在使用terraform的编译版本

I'm using compiled version of terraform

$ terraform --version
Terraform v0.7.0-dev (854c9bd488dfdb12303ec47e42d6de8fc17e40a5)

推荐答案

检查 CHANGELOG (在升级版本之前，最好先使用Terraform，因为它们会不断开发并经常进行非向后兼容的更改.)

Check the CHANGELOG (always a good idea with Terraform before upgrading versions as they are constantly developing and frequently make non-backwards-compatible changes.)

0.7(未发布)

0.7 (Unreleased)

向后的不兼容/注意:

[...]

• concat()插值函数不能再用于连接字符串.

[...]

• 您现在可以使用var.map ["key"]语法或 查找功能而不是var.map.key.

• You now access the values of maps using the syntax var.map["key"] or the lookup function instead of var.map.key.
