Provisioned service

Provisioned service represents a backing service CR with a reference to a Secret resource placed in the .status.binding.name field of the backing service CR.

As an Operator provider or the user who creates backing services, you can use this method to be compliant with the Service Binding specification, by creating a Secret resource and referencing it in the .status.binding.name section of the backing service CR. This Secret resource must provide all the binding data values required for a workload to connect to the backing service.

The following examples show an AccountService CR that represents a backing service and a Secret resource referenced from the CR.

Example: AccountService CR

apiVersion: example.com/v1alpha1
kind: AccountService
name: prod-account-service
spec:
  ...
status:
  binding:
    name: production-db-secret

Example: Referenced Secret resource

apiVersion: v1
kind: Secret
metadata:
  name: production-db-secret
data:
  password: "MTBz"
  user: "Z3Vlc3Q="
  ...

When creating a service binding resource, you can directly give the details of the AccountService resource in the ServiceBinding specification as follows:

Example: ServiceBinding resource

apiVersion: binding.operators.coreos.com/v1alpha1
kind: ServiceBinding
metadata:
  name: account-service
spec:
  ...
  services:
  - group: "example.com"
    version: v1alpha1
    kind: AccountService
    name: prod-account-service
  application:
    name: nodejs-app
    group: apps
    version: v1
    resource: deployments

Example: ServiceBinding resource in Specification API

apiVersion: servicebinding.io/v1alpha3
kind: ServiceBinding
metadata:
  name: account-service
spec:
  ...
  service:
    apiVersion: example.com/v1alpha1
    kind: AccountService
    name: prod-account-service
  workload:
    apiVersion: apps/v1
    kind: Deployment
    name: nodejs-app

This method exposes all the keys in the production-db-secret referenced Secret resource as binding data that is to be projected into the workload.
