     * Simplified way to run a container on every node (DaemonSet API (Beta) in the
Extensions API group): Kubernetes can schedule a service (such as a logging
agent) that runs one, and only one, pod per node.

- [ ] Security testing (authentication, authorization)
- [ ] Integration testing with client applications
- [ ] User acceptance testing
- [ ] Load testing for production capacity

### Go-Live

- [ ] Schedule maintenance window
- [ ] Final incremental data sync
- [ ] Switch DNS or endpoints to Fess
- [ ] Monitor logs for errors
- [ ] Monitor search performance metrics
- [ ] Have rollback plan ready

### Additional changes

* Extended the Stackdriver Metadata Agent by adding a new Deployment for ingesting unscheduled pods and services.   ([#62043](https://github.com/kubernetes/kubernetes/pull/62043), [@supriyagarg](https://github.com/supriyagarg))
