The Service Binding Operator consists of a controller and an accompanying custom resource definition (CRD) for service binding. It manages the data plane for workloads and backing services. The Service Binding Controller reads the data made available by the control plane of backing services. Then, it projects this data to workloads according to the rules specified through the ServiceBinding resource.

With Service Binding Operator, you can:

  • Bind your workloads together with Operator-managed backing services.

  • Automate configuration of binding data.

  • Provide service operators a low-touch administrative experience to provision and manage access to services.

  • Enrich development lifecycle with a consistent and declarative service binding method that eliminates discrepancies in cluster environments.

Making open source more inclusive

Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see Red Hat CTO Chris Wright’s message.

Release notes for Service Binding Operator 1.0

Service Binding Operator is now available on OKD 4.7, 4.8 and 4.9.

The custom resource definition (CRD) of the Service Binding Operator 1.0 supports the following APIs:

  • Service Binding with the binding.operators.coreos.com API group.

  • Service Binding (Spec API Tech Preview) with the servicebinding.io API group.

    Service Binding (Spec API Tech Preview) with the servicebinding.io API group 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.
