檢視變更集
建立變更集之後,即可先檢視請求的變更,再加以執行。您可以使用 CloudFormation 控制台 AWS CLI、或 CloudFormation API來檢視變更集。主 CloudFormation 控台會提供變更摘要,以及JSON格式變更的詳細清單。 AWS CLI 並 AWS CloudFormation API返回格式更改的詳細列JSON表。
檢視變更集 (AWS CLI)
-
執行
aws cloudformation list-change-sets
命令,即可取得變更集的 ID。指定堆疊 ID,該堆疊內含您要檢視的變更集;如以下範例所示:
$
aws cloudformation list-change-sets \ --stack-name arn:aws:cloudformation:us-east-1:123456789012:stack/SampleStack/1a2345b6-0000-00a0-a123-00abc0abc000
CloudFormation 會傳回變更集清單,類似下列內容:
{ "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" } ] }
-
執行
aws cloudformation describe-change-set
命令,藉此指定要檢視的變更集 ID。例如:$
aws cloudformation describe-change-set --change-set-name arn:aws:cloudformation:us-east-1:123456789012:changeSet/SampleChangeSet/1a2345b6-0000-00a0-a123-00abc0abc000
CloudFormation 返回有關指定變更集的信息:
{ "StackId": "arn:aws:cloudformation:us-east-1:123456789012:stack/SampleStack/1a2345b6-0000-00a0-a123-00abc0abc000", "Status": "CREATE_COMPLETE", "ChangeSetName": "SampleChangeSet-direct", "Parameters": [ { "ParameterValue": "testing", "ParameterKey": "Purpose" }, { "ParameterValue": "ellioty-useast1", "ParameterKey": "KeyPairName" }, { "ParameterValue": "t2.micro", "ParameterKey": "InstanceType" } ], "Changes": [ { "ResourceChange": { "ResourceType": "AWS::EC2::Instance", "PhysicalResourceId": "i-1abc23d4", "Details": [ { "ChangeSource": "DirectModification", "Evaluation": "Static", "Target": { "Attribute": "Tags", "RequiresRecreation": "Never" } } ], "Action": "Modify", "Scope": [ "Tags" ], "LogicalResourceId": "MyEC2Instance", "Replacement": "False" }, "Type": "Resource" } ], "CreationTime": "2020-11-18T23:35:25.813Z", "Capabilities": [], "StackName": "SampleStack", "NotificationARNs": [], "ChangeSetId": "arn:aws:cloudformation:us-east-1:123456789012:changeSet/SampleChangeSet-direct/9edde307-960d-4e6e-ad66-b09ea2f20255" }
--include-property-values
搭配使用describe-change-set
可列出屬性層級的變更。Changes
金鑰會列出系統對資源進行的變更。如果您要執行此變更集,則 CloudFormation 會更新執行個i-1abc23d4
EC2體的標籤。如需每個欄位的說明,請參閱「AWS CloudFormation API參考」中的Change
資料類型。如需變更集的其他範例,請參閱變更集範例。

下列命令會列出與
AWS::EC2::NetworkInterface
資源變更集相關的屬性層級變更,這些變更將會移除Ipv4Prefixes
屬性、修改資源Description
