使用elseif在Terraform三元运算中使用多个条件进行计数

Question

我试图让terraform如下基于count条件创建一个资源，我无法理解语法，应该是下面的样子：

count = “${var.size[terraform.workspace] == "big" ? && local.ips[terraform.workspace] != “<none>“} then 10
elseif
${var.size[terraform.workspace] == "small"  && local.ips[terraform.workspace] != “<none>” } then 20
else 0 

Answer 1

在下面测试

count = "${lookup(var.size, terraform.workspace, "None") == "big" && lookup(local.ips, terraform.workspace, "None") != "None" ? 10 : lookup(var.size, terraform.workspace, "None") == "small" && lookup(local.ips, terraform.workspace, "None") != "None" ? 20 : 0}"
