我想要使用個別參數的多個值,從 AWS CloudFormation 範本建立或更新堆疊。

簡短描述

可以使用下列其中一種方式,在 AWS CloudFormation 範本中為個別參數傳遞多個值:

解決方法

使用 AWS 特定的參數類型,從 AWS 帳戶中預先填入的現有 AWS 值清單中選取值

**重要事項:**AWS CloudFormation 會根據帳戶中的現有值驗證您選取的輸入值。

在這些 AWS CloudFormation 範本範例中,具有 SecurityGroups 金鑰的參數可指定 AWS 特定的參數類型,該參數類型可接受 SecurityGroupIds 的多個值。

JSON 範本:

{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Parameters": {
    "SecurityGroups": {
      "Type": "List<AWS::EC2::SecurityGroup::Id>",
      "Description": "The list of SecurityGroupIds in your Virtual Private Cloud (VPC)"
    }
  },
  "Resources": {
    "MyEC2Instance": {
      "Type": "AWS::EC2::Instance",
      "Properties": {
        "ImageId": "ami-79fd7eee",
        "KeyName": "testkey",
        "SecurityGroupIds": {
          "Ref": "SecurityGroups"
        }
      }
    }
  }
}

YAML 範本:

AWSTemplateFormatVersion: 2010-09-09
Parameters:
  SecurityGroups:
    Type: 'List<AWS::EC2::SecurityGroup::Id>'
    Description: The list of SecurityGroupIds in your Virtual Private Cloud (VPC)
Resources:
  MyEC2Instance:
    Type: 'AWS::EC2::Instance'
    Properties:
      ImageId: ami-79fd7eee
      KeyName: testkey
      SecurityGroupIds: !Ref SecurityGroups

若要使用 AWS CLI 部署堆疊,請使用下列命令:

**注意:**用堆疊的名稱取代 StackName。用檔案的名稱取代 TemplateFileName。對於 ParameterValue,請輸入安全群組 ID。

aws cloudformation create-stack --stack-name StackName --template-body file://TemplateFileName
--parameters ParameterKey=SecurityGroups,ParameterValue="sg-0123456789\,sg-2345678901"

使用 CommaDelimitedList 參數類型來輸入輸入值

在下列 AWS CloudFormation 範本範例中,具有 SecurityGroups 金鑰的參數可指定 CommaDelimitedList 類型,該類型可接受 SecurityGroupIds 的多個值。

JSON 範本:

{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Parameters": {
    "SecurityGroups": {
      "Type": "CommaDelimitedList",
      "Description": "The list of SecurityGroupIds in your Virtual Private Cloud (VPC)",
      "Default": "sg-a123fd85, sg-b456ge94"
    }
  },
  "Resources": {
    "MyEC2Instance": {
      "Type": "AWS::EC2::Instance",
      "Properties": {
        "ImageId": "ami-79fd7eee",
        "KeyName": "testkey",
        "SecurityGroupIds": {
          "Ref": "SecurityGroups"
        }
      }
    }
  }
}

YAML 範本:

AWSTemplateFormatVersion: 2010-09-09
Parameters:
  SecurityGroups:
    Type: CommaDelimitedList
    Description: The list of SecurityGroupIds in your Virtual Private Cloud (VPC)
    Default: sg-a123fd85, sg-b456ge94
Resources:
  MyEC2Instance:
    Type: 'AWS::EC2::Instance'
    Properties:
      ImageId: ami-79fd7eee
      KeyName: testkey
      SecurityGroupIds: !Ref SecurityGroups
