Visualización de un conjunto de cambios
Después de crear un conjunto de cambios, puede ver los cambios propuestos antes de ejecutarlos. Puede utilizar la consola de CloudFormation, la AWS CLI o la API de CloudFormation para ver los conjuntos de cambios. La consola de proporciona un resumen de los cambios y una lista detallada de los cambios en formato JSON. Las API de AWS CLI y AWS CloudFormation devolverán una lista detallada de los cambios en formato JSON.
Ver un conjunto de cambios (AWS CLI)
-
Para obtener el ID del conjunto de cambios, ejecute el comando
aws cloudformation list-change-sets
.Especifique el ID de pila de la pila que tenga el conjunto de cambios que desea ver, tal y como se muestra en el ejemplo siguiente:
$
aws cloudformation list-change-sets \ --stack-name arn:aws:cloudformation:us-east-1:123456789012:stack/SampleStack/1a2345b6-0000-00a0-a123-00abc0abc000
CloudFormation devuelve una lista de conjuntos de cambios, similar a esta:
{ "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" } ] }
-
Ejecute el comando
aws cloudformation describe-change-set
, especificando el ID del conjunto de cambios que desea ver. Por ejemplo:$
aws cloudformation describe-change-set --change-set-name arn:aws:cloudformation:us-east-1:123456789012:changeSet/SampleChangeSet/1a2345b6-0000-00a0-a123-00abc0abc000
CloudFormation devuelve información sobre el conjunto de cambios especificado:
{ "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" }
Utilice
--include-property-values
condescribe-change-set
para enumerar los cambios a nivel de propiedad.La clave
Changes
enumera los cambios de los recursos. Si fuera a ejecutar este conjunto de cambios, CloudFormation actualizaría las etiquetas de la instancia de EC2i-1abc23d4
. Para obtener una descripción de cada campo, consulteChange
el tipo de datos en la referencia de la API de AWS CloudFormation.Para obtener más ejemplos de conjuntos de cambio, consulte Ejemplo de conjuntos de cambio.
