OpenSearch domains should have the latest software update installed

Checks that the OpenSearch domain, on either engine, has no service software update waiting, so it runs the latest platform fixes, including security fixes. It fails while an update is available, scheduled or still installing.

How to fix it

  • Interrupts service: The update runs as a blue/green deployment, so latency and rejected requests can rise while data copies, and on a busy cluster it can take hours.

In the console

OpenSearch Service → Domains → the domain → Actions → Update

Apply update now
Selected at low traffic, or Schedule it in off-peak window to run in the domain's quiet hours

With the AWS CLI

aws opensearch start-service-software-update --domain-name <domain-name> --schedule-at NOW --region <region>
