Create a Kubernetes Secret from a Cloud Foundry Service Key

There are some reasons why you want to access a service instance created from Cloud Foundry from Kyma:

  • There are some services that do not allow creation from Kubernetes/Kyma, for example SAP HANA Cloud and Workflow.
  • You want to try out your Kyma application with an existing Cloud Foundry service instance.
  • ...

This sample shows how to create a Kubernetes secret from a Cloud Foundry service key, that can be used by any application that can consume servicebinding.io and SAP BTP Service Operator service bindings.

Usage

node create-k8s-secret-from-cf-service-key.js CF-SERVICE-INSTANCE-NAME [CF-SERVICE-KEY-NAME]

Example Usage

cf create-service hana hdi-shared my-hdi-container
cf create-service-key my-hdi-container my-hdi-key
node create-k8s-secret-from-cf-service-key.js my-hdi-container my-hdi-key | kubectl apply -f -

This creates a secret from the credentials of the HDI container service key.

Details

A secret property needs to be created for each top-level property of the service key. Non-string properties, such as arrays, objects, integers or booleans are serialized as JSON.

Additionally the secret contains properties for tags, label, type (same as label), plan, instance_name and instance_guid. These properties may be used by applications to find the desired service instance.

The .metadata property contains a JSON string that describes the credential properties (credentialProperties) and the properties that describe the service (metaDataProperties).
