Question

我在terraform 0.11.14上，我具有aws_cloudformation_stack资源，如下所示：

resource "aws_cloudformation_stack" "ingress_sg" {
  name = "bastion-${var.accountName}-ingressIntuitIPs"

  lifecycle {
    prevent_destroy = true
  }

  parameters {
    VpcId = "${var.default_vpc_id}"
    Port = 22
    Name = "bastion-${var.accountName}-ingressIntuitIPs"
    GroupName = "true"
  }
  }```

when i run terraform, its throwing this error:

```Error: module.swimlane.module.bastion.aws_cloudformation_stack.ingress_sg: 1 error occurred:
    * module.swimlane.module.bastion.aws_cloudformation_stack.ingress_sg: invalid variable syntax: "VpcId". Did you mean 'var.VpcId'? If this is part of inline `template` parameter
then you must escape the interpolation with two dollar signs. For
example: ${a} becomes $${a}.

感谢您的帮助。预先感谢。

Answer 1

错误消息确切说明了您需要执行的操作：

"you must escape the interpolation with two dollar signs. For
example: ${a} becomes $${a}."

表示

VpcId = "${var.default_vpc_id}"

成为

VpcId = "$${var.default_vpc_id}"

Answer 2

在模板主体中添加多余的美元符号，如下所示解决了该问题：

template_body = <<STACK ..Outputs: SecurityGroupId: Condition: CreateSecurityGroup Export: Name: !Sub $${VpcId}:$${Name}-tcp-$${Port}:id Value: !Ref SecurityGroup STACK }

terraform变量声明错误
