使用 heredoc 字符串打印地图变量

Question

我正在尝试使用 heredoc 示例在 terraform 中打印地图变量：

 description = <<EOT
  Hello Check ${local.map_variable1} and $local.map_variable2} 
EOT

我的地图变量如下：

> local.map_variable1
{
  "server_1" = "100.100.50.101"
  "server_2" = "100.100.50.102"
  "server_3" = "100.100.50.103"
  "server_4" = "100.100.50.104"
}
> local.map_variable2
{
  "Application_node1" = "100.100.51.101"
  "Application_node2" = "100.100.52.102"
  "Application_node3" = "100.100.53.103"
  "Application_node4" = "100.100.54.104"
}

错误：无法在字符串模板中包含给定值：需要字符串。

关于如何打印地图变量的任何建议

最好使用 jsonencode:

将变量转换为 json 字符串

description = <<EOT
  Hello Check ${jsonencode(local.map_variable1)} and ${jsonencode(local.map_variable2)} 
EOT

使用 heredoc 字符串打印地图变量
