SAP BTP Service Operator Examples

This document describes notable features shipped with new SAP BTP service operator upgrades discovered during the application of latest versions.

Secret Templates

Version 0.6.1 introduced a Secret templates feature that allows for modification of a Secret's content that is normally generated from a ServiceBinding instance created for any service. You can now specify a data-driven template as a value of the secretTemplate field inside the binding's spec section. Inside the template, you can refer (by using {{}} syntax) to credentials stored inside of a ServiceBinding (with {{credentials.<key>}}) or information of a given instance (with {{instance.<key>}}). The parameters that can be used with the instance key are limited to the values set in the getInstanceInfo method. Here is an example of a ServiceBinding with the secretTemplate field:

apiVersion: services.cloud.sap.com/v1
kind: ServiceBinding
metadata:
  labels:
    app.kubernetes.io/name: nice-script
  name: nice-script
  namespace: default
spec:
  externalName: nice-script
  secretName: nice-script
  secretTemplate: |
    apiVersion: v1
    kind: Secret
    metadata:
      labels:
        instance_plan: {{ .instance.plan }}
      annotations:
        instance_name: {{ .instance.instance_name }}
    data:
      foo: {{ .instance.type }}
      bar: {{ .credentials.url }}
  serviceInstanceName: dimpled-editor
