Cloudformation is giving Update_rollback_complete status even that resource is not present?












0














I am testing rollback scenarios in cloudformation. My usecase is like this



I am creating a DynamoDB resource using below template



{
"AWSTemplateFormatVersion" : "2010-09-09",
"Resources" : {
"myDynamoDBTable" : {
"Type" : "AWS::DynamoDB::Table",
"Properties" : {
"AttributeDefinitions" : [
{
"AttributeName" : "Name",
"AttributeType" : "S"
}
],
"KeySchema" : [
{
"AttributeName" : "Name",
"KeyType" : "HASH"
}
],
"ProvisionedThroughput" : {
"ReadCapacityUnits" : "5",
"WriteCapacityUnits" : "5"
},
"TableName" : "TableONE"
}
}
}
}


This template will create a dynamodb table with tablename TableONE .
Step 2: Now, I am deleting the resource(i.e.dynamdob) via console.
Step 3: And i am updating the cloudformation stack from console and i am passing same template with different read and write capacities, here is my template.



{
"AWSTemplateFormatVersion" : "2010-09-09",
"Resources" : {
"myDynamoDBTable" : {
"Type" : "AWS::DynamoDB::Table",
"Properties" : {
"AttributeDefinitions" : [
{
"AttributeName" : "Name",
"AttributeType" : "S"
}
],
"KeySchema" : [
{
"AttributeName" : "Name",
"KeyType" : "HASH"
}
],
"ProvisionedThroughput" : {
"ReadCapacityUnits" : "3",
"WriteCapacityUnits" : "3"
},
"TableName" : "TableONE"
}
}
}
}


Now, Here is the console events



2018-11-23          Status                                                Type                                          Logical ID                           Status Reason
14:43:30 UTC+0550 UPDATE_ROLLBACK_COMPLETE AWS::CloudFormation::Stack Amigo
14:43:29 UTC+0550 UPDATE_ROLLBACK_COMPLETE_CLEANUP_IN_PROGRESS AWS::CloudFormation::Stack Amigo
14:43:28 UTC+0550 UPDATE_COMPLETE AWS::DynamoDB::Table myDynamoDBTable
14:43:14 UTC+0550 UPDATE_ROLLBACK_IN_PROGRESS AWS::CloudFormation::Stack Amigo The following resource(s) failed to update: [myDynamoDBTable].
14:43:13 UTC+0550 UPDATE_FAILED AWS::DynamoDB::Table myDynamoDBTable Requested resource not found: Table: TableONE not found (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: ResourceNotFoundException; Request ID: xxxxxxxxxxxx)
14:43:12 UTC+0550 UPDATE_IN_PROGRESS AWS::DynamoDB::Table myDynamoDBTable
14:43:09 UTC+0550 UPDATE_IN_PROGRESS AWS::CloudFormation::Stack Amigo User Initiated


Here it is clearly saying that the resource not found which is good, but after that update_rollback_in_progress got started and completed just fine.



How can it will complete if i dont have that resource itself ?



Does my understanding is right ?



Thanks
