Similarly you can create other applications and components and establish connections between them. Service Binding 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  https://access.redhat.com/support/offerings/techpreview/ . Currently, a few specific Operators like the  etcd  and the  PostgresSQL Database Operator’s service instances are bindable. You can establish a binding connection with Operator-backed components. This procedure walks through an example of creating a binding connection between a PostgreSQL Database service and a Node.js application. To create a binding connection with a service that is backed by the PostgreSQL Database Operator, you must first add the Red Hat-provided PostgreSQL 35 NOTE IMPORTANT 2.4.6.2.
