How to remove RDS pending maintenance item

Hi,

You can defer the maintenance or apply it to remove the item from pending maintenance. However consider the below points before you take a decision.

OS updates are available for RDS in 2 categories, Optional and Mandatory. From the RDS console, you can take a look under maintenance&backups tab to determine this.

• An optional update has its maintenance Status set to available and doesn't have an Apply date.
• A mandatory update has its maintenance Status set to required and has an Apply date.

You can also determine this using CLI with below command.

aws rds describe-pending-maintenance-actions

A mandatory update will have "AutoAppliedAfterDate" and the updates will be installed.

If an update is available, you can take one of the actions:

• If the maintenance value is next window, defer the maintenance items by choosing Defer upgrade from Actions. You can't defer a maintenance action if it has already started.
• Apply the maintenance items immediately.
• Schedule the maintenance items to start during your next maintenance window.
• Take no action.

Refer to documentation for more details regarding OS updates for RDS.
