Red Hat Summit3.11.12. Installation configuration for a cluster on OpenStack with a user-managed load balancer
Deployment on OpenStack with User-Managed Load Balancers is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.
The following example install-config.yaml file demonstrates how to configure a cluster that uses an external, user-managed load balancer rather than the default internal load balancer.

- Regardless of which load balancer you use, the load balancer is deployed to this subnet.
- 2
- The
UserManagedvalue indicates that you are using an user-managed load balancer. - 3
- Because user-managed load balancers are in Technology Preview, you must include the
TechPreviewNoUpgradevalue to deploy a cluster that uses a user-managed load balancer.
