查看更改集
创建更改集之后，您可在执行之前查看提议的更改。您可以使用 CloudFormation 控制台、Amazon CLI 或 CloudFormation API 查看更改集。CloudFormation 控制台提供了更改摘要以及 JSON 格式的更改详细列表。Amazon CLI 和 Amazon CloudFormation API 以 JSON 格式返回详细的更改列表。

要获取更改集的 ID，请运行 change-sets 命令。
指定具有您要查看的更改集的堆栈的堆栈 ID，如下例中所示：
aws cloudformation list-change-sets \ --stack-namearn:aws:cloudformation:us-east-1:123456789012:stack/SampleStack/1a2345b6-0000-00a0-a123-00abc0abc000CloudFormation 返回更改集列表，类似于以下内容：
{ "Summaries": [ { "StackId": "arn:aws:cloudformation:us-east-1:123456789012:stack/SampleStack/1a2345b6-0000-00a0-a123-00abc0abc000", "Status": "CREATE_COMPLETE", "ChangeSetName": "SampleChangeSet", "CreationTime": "2020-11-18T20:44:05.889Z", "StackName": "SampleStack", "ChangeSetId": "arn:aws:cloudformation:us-east-1:123456789012:changeSet/SampleChangeSet/1a2345b6-0000-00a0-a123-00abc0abc000" }, { "StackId": "arn:aws:cloudformation:us-east-1:123456789012:stack/SampleStack/1a2345b6-0000-00a0-a123-00abc0abc000", "Status": "CREATE_COMPLETE", "ChangeSetName": "SampleChangeSet-conditional", "CreationTime": "2020-11-18T21:15:56.398Z", "StackName": "SampleStack", "ChangeSetId": "arn:aws:cloudformation:us-east-1:123456789012:changeSet/SampleChangeSet-conditional/1a2345b6-0000-00a0-a123-00abc0abc000" }, { "StackId": "arn:aws:cloudformation:us-east-1:123456789012:stack/SampleStack/1a2345b6-0000-00a0-a123-00abc0abc000", "Status": "CREATE_COMPLETE", "ChangeSetName": "SampleChangeSet-replacement", "CreationTime": "2020-11-18T21:03:37.706Z", "StackName": "SampleStack", "ChangeSetId": "arn:aws:cloudformation:us-east-1:123456789012:changeSet/SampleChangeSet-replacement/1a2345b6-0000-00a0-a123-00abc0abc000" } ] } -
运行 describe-change-set 命令，指定您要查看的更改集的 ID。例如：
aws cloudformation describe-change-set \ --change-set-namearn:aws:cloudformation:us-east-1:123456789012:changeSet/SampleChangeSet/1a2345b6-0000-00a0-a123-00abc0abc000CloudFormation 返回有关指定更改集的信息。

--include-property-values与 describe-change-set 结合使用可列出属性级别的更改。Changes键列出对资源的更改。如果您要执行此更改集，CloudFormation 将更新i-1abc23d4EC2 实例的标签。有关各字段的说明，请参阅《Amazon CloudFormation API 参考》中的Change数据类型。有关更改集的其他示例，请参阅示例更改集。
