Story (Required)

As a developer working on integrating Service Binding into my tools/system, I would like to
to discover services that can be bound using Service Binding operator

Background (Required)

Various dev tools and dev console would like to render to users services that can be then bound to applications using Service Binding operator.

In Scope

• SBO logic that actively discovers and marks a service as bindable
• SBO logic embeddable in 3rd party codebases, so that bindable service can be detected on demand

Approach(Required)

• Watch for CustomResourceDefinition changes, and try to find servicebinding annotatons, or figure out if CRD defines a provisioned services. If CRD is owned by a ClusterServiceVersion, check if service binding descriptors are defined. In case of match, set an annotation on CRD indicating that CRs are potentially bindable:

service.binding/bindable: true

• Provide a custom CRD with a cluster-scoped instance listing all bindable GVKs (GroupVersionKind):

apiVersion: binding.operators.coreos.com/v1alpha1
kind: BindableKinds
metadata: 
  name: bindable-kinds
status: 

  - group: foo
    version: v1alpha1
    kind: Service
  - group: bar
    version: v1beta1
    kind: Service

Acceptance Criteria

• acceptance tests demonstrating service discovery
• code example showing how to embed the logic into 3rd party codebase

• INVEST Checklist
