RDS Database Stack | Update Storage

Change the RDS instance storage type, capacity or IOPS through direct API calls. The RDS instance can be standalone or belong to a CloudFormation stack, in the latter case, the change might cause stack drift. To avoid causing stack drift, please use ct-12w49boaiwtzp instead, or ct-361tlo1k7339x if the RDS instance was provisioned via CFN ingestion.

Screenshot of this change type in the AMS console:

Update RDS Storage interface showing ID, execution mode, version, and description fields.

How it works:

  1. Navigate to the Create RFC page: In the left navigation pane of the AMS console click RFCs to open the RFCs list page, and then click Create RFC.

  2. Choose a popular change type (CT) in the default Browse change types view, or select a CT in the Choose by category view.

    • Browse by change type: You can click on a popular CT in the Quick create area to immediately open the Run RFC page. Note that you cannot choose an older CT version with quick create.

      To sort CTs, use the All change types area in either the Card or Table view. In either view, select a CT and then click Create RFC to open the Run RFC page. If applicable, a Create with older version option appears next to the Create RFC button.

    • Choose by category: Select a category, subcategory, item, and operation and the CT details box opens with an option to Create with older version if applicable. Click Create RFC to open the Run RFC page.

  3. On the Run RFC page, open the CT name area to see the CT details box. A Subject is required (this is filled in for you if you choose your CT in the Browse change types view). Open the Additional configuration area to add information about the RFC.

    In the Execution configuration area, use available drop-down lists or enter values for the required parameters. To configure optional execution parameters, open the Additional configuration area.

  4. When finished, click Run. If there are no errors, the RFC successfully created page displays with the submitted RFC details, and the initial Run output.

  5. Open the Run parameters area to see the configurations you submitted. Refresh the page to update the RFC execution status. Optionally, cancel the RFC or create a copy of it with the options at the top of the page.

How it works:

  1. Use either the Inline Create (you issue a create-rfc command with all RFC and execution parameters included), or Template Create (you create two JSON files, one for the RFC parameters and one for the execution parameters) and issue the create-rfc command with the two files as input. Both methods are described here.

  2. Submit the RFC: aws amscm submit-rfc --rfc-id ID command with the returned RFC ID.

    Monitor the RFC: aws amscm get-rfc --rfc-id ID command.

To check the change type version, use this command:

aws amscm list-change-type-version-summaries --filter Attribute=ChangeTypeId,Value=CT_ID
Note

You can use any CreateRfc parameters with any RFC whether or not they are part of the schema for the change type. For example, to get notifications when the RFC status changes, add this line, --notification "{\"Email\": {\"EmailRecipients\" : [\"email@example.com\"]}}" to the RFC parameters part of the request (not the execution parameters). For a list of all CreateRfc parameters, see the AMS Change Management API Reference.

INLINE CREATE:

Issue the create RFC command with execution parameters provided inline (escape quotation marks when providing execution parameters inline), and then submit the returned RFC ID. For example, you can replace the contents with something like this:

aws amscm create-rfc --change-type-id "ct-0loed9dzig1ze" --change-type-version "1.0" --title "Update RDS storage" --execution-parameters "{\"DocumentName\":\"AWSManagedServices-UpdateRDSStorage\",\"Region\":\"us-east-1\",\"Parameters\": {\"DBInstanceIdentifier\":[\"rt123456789\"], \"AllocatedStorage\": [\"100\"],,\"ApplyImmediately\": \"true\"}}"

TEMPLATE CREATE:

  1. Output the execution parameters for this change type to a JSON file named UpdateStorageParams.json.

    aws amscm get-change-type-version --change-type-id "ct-0loed9dzig1ze" --query "ChangeTypeVersion.ExecutionInputSchema" --output text > UpdateStorageParams.json

  2. Modify and save the execution parameters JSON file. For example, you can replace the contents with something like this:

    {
  "DocumentName": "AWSManagedServices-UpdateRDSStorage",
  "Region": "us-east-1",
  "Parameters": {
    "DBInstanceIdentifier": [
      "rt123456789"
    ],
    "AllocatedStorage": [
      "100"
    ],
    "ApplyImmediately": "false"
  }
}

  3. Output the JSON template to a file in your current folder; this example names it UpdateStorageRfc.json:

    aws amscm create-rfc --generate-cli-skeleton > UpdateStorageRfc.json

  4. Modify and save the UpdateStorageRfc.json file. For example, you can replace the contents with something like this:

    {
"ChangeTypeVersion":    "1.0",
"ChangeTypeId":         "ct-0loed9dzig1ze",
"Title":                "Update RDS storage"
}

  5. Create the RFC, specifying the execution parameters file and the UpdateStorageRfc file:

    aws amscm create-rfc --cli-input-json file://UpdateStorageRfc.json --execution-parameters file://UpdateStorageParams.json

    You receive the ID of the new RFC in the response and can use it to submit and monitor the RFC. Until you submit it, the RFC remains in the editing state and does not start.

Note

AMS employs drift detection on certain stacks, including RDS stacks, to determine if configuration changes. The AMS disallows updates to an RDS stack that has been determined to have configuration drift. The RFC will fail with the following error message: "Update cannot be performed on this stack, please contact AMS for further assistance."
