Features

This section highlights the key features introduced with Cloud-Native Contrail Networking Release 22.3. A brief description of each new feature follows.

Cluster Security

Kubernetes Network Policy matchExpressions—Starting in Cloud-Native Contrail Networking Release 22.3, CN2 supports Kubernetes Network Policy with matchExpressions. For information about matchExpressions, see "Resources that support set-based requirements" in the Kubernetes documentation.

Services

Configure LoadBalancer Services without Selectors—Starting in Cloud-Native Contrail Networking Release 22.3, you can now load balance a service across multiple secondary interfaces. Kubernetes uses selectors to automatically create a LoadBalancer service, but only uses the default primary interface for load balancing. This feature allows you to create secondary interfaces in CN2 without using a selector.

See Create a LoadBalancer Service.

Telemetry and Analytics

Health Check Object—Starting in Cloud-Native Contrail Networking Release 22.3, a new health check custom resource object is introduced that associates the virtual machine interface (VMI) to the pod creation and update workflow.

See Health Check Object.

Tech Previews for 22.3

Introducing Tech Preview Features—Starting in Cloud-Native Contrail Networking Release 22.2, Tech Previews were introduced. Tech Previews give you the ability to test functionality and provide feedback during the development process of innovations that are not final production features.
