aws-cloudformation - 在 `aws cloudformation deploy --parameter-overrides` 中，如何将多个值传递给 `List` 参数？

Question

我正在使用this CloudFormation template

我尝试传递值的列表参数是:

"Subnets" : {
  "Type" : "List<AWS::EC2::Subnet::Id>",
  "Description" : "The list of SubnetIds in your Virtual Private Cloud (VPC)",
  "ConstraintDescription" : "must be a list of at least two existing subnets associated with at least two different availability zones. They should be residing in the selected Virtual Private Cloud."
},

我编写了一个实用程序脚本，如下所示:

#!/bin/bash
SUBNET1=subnet-abcdef
SUBNET2=subnet-ghijlm
echo -e "\n==Deploying stack.cf.yaml===\n"
aws cloudformation deploy \
  --region $REGION \
  --profile $CLI_PROFILE \
  --stack-name $STACK_NAME \
  --template-file stack.cf.json \
  --no-fail-on-empty-changeset \
  --capabilities CAPABILITY_NAMED_IAM \
  --parameter-overrides \
    VpcId=$VPC_ID \
    Subnets="$SUBNET1 $SUBNET2" \ #<---------------this fails
    InstanceType=$EC2_INSTANCE_TYPE \
    OperatorEMail=$OPERATOR_EMAIL \
    KeyName=$KEY_NAME \

如果我部署此功能，一段时间后我的堆栈将无法部署，并提示值为“subnet-abcdefsubnet-ghijlmn”的子网不存在。

向列表传递参数的正确方法是用逗号分隔它们

所以:

#!/bin/bash
SUBNET1=subnet-abcdef
SUBNET2=subnet-ghijlm
aws cloudformation deploy --parameter-overrides Subnets="$SUBNET1,SUBNET2"

可以工作
