从terraform中的字符串列表中获取子字符串

Question

有一个字符串列表，这些字符串是vnet对等详细信息的输出。我需要提取一个列表中的所有源vnet名称和另一个列表的目标vnet名称。我的vnet对等名称如下

Peer =["vnet1tovnet2",
"vnet1tovnet3",
"vnet4tovnet5"]

我需要两个以下格式的列表

source=["vnet1","vnet1",vnet4"]
dest=["vnet2","vnet3","vnet5"]

如何在地形中实现这一点

Answer 1

您可以按如下方式执行：

locals{
Peer =["vnet1tovnet2",
"vnet1tovnet3",
"vnet4tovnet5"]

source = [for v in local.Peer: split("to", v)[0]]
dest = [for v in local.Peer: split("to", v)[1]]
}
