SAP Business Technology Platform (SAP BTP) Service Operator for Kubernetes

With the SAP BTP service operator, you can consume SAP BTP services from your Kubernetes cluster using Kubernetes-native tools. SAP BTP service operator allows you to provision and manage service instances and service bindings of SAP BTP services so that your Kubernetes-native applications can access and use needed services from the cluster.
The SAP BTP service operator is based on the Kubernetes Operator pattern.

Table of Contents

Architecture

SAP BTP service operator communicates with Service Manager that uses the Open service broker API to communicate with service brokers, acting as an intermediary for the Kubernetes API Server to negotiate the initial provisioning and retrieve the credentials necessary for the application to use a managed service.

It is implemented using a CRDs-based architecture.

Setup

  1. Install cert-manager

    • for releases v0.1.18 or higher use cert-manager v1.6.0 or higher
    • for releases v0.1.17 or lower use cert-manager lower than v1.6.0

  2. Obtain the access credentials for the SAP BTP service operator:

    • Create an instance of the SAP Service Manager service (technical name: service-manager) with the plan: service-operator-access
      *Note:
      If you can't see the needed plan, you need to entitle your subaccount to use SAP Service Manager service.For more information about how to entitle a service to a subaccount, see:Configure Entitlements and Quotas for Subaccounts
      For more information about creating service instances, see:

    • Create a binding to the created service instance.

      For more information about creating service bindings, see:

    • Retrieve the generated access credentials from the created binding:

      The example of the default binding object used if no credentials type is specified:

       {
     "clientid": "xxxxxxx",
     "clientsecret": "xxxxxxx",
     "url": "https://mysubaccount.authentication.eu10.hana.ondemand.com",
     "xsappname": "b15166|service-manager!b1234",
     "sm_url": "https://service-manager.cfapps.eu10.hana.ondemand.com"
 }

      The example of the binding object with the specified X.509 certificate:

      {
     "clientid": "xxxxxxx",
     "certificate": "-----BEGIN CERTIFICATE-----...-----END CERTIFICATE-----\n-----BEGIN CERTIFICATE-----..-----END CERTIFICATE-----\n-----BEGIN CERTIFICATE-----...-----END CERTIFICATE-----\n",
     "key": "-----BEGIN RSA PRIVATE KEY-----...-----END RSA PRIVATE KEY-----\n",
     "certurl": "https://mysubaccount.authentication.cert.eu10.hana.ondemand.com",
     "xsappname": "b15166|service-manager!b1234",
     "sm_url": "https://service-manager.cfapps.eu10.hana.ondemand.com"
 }

  3. Add SAP BTP service operator chart repository

     helm repo add sap-btp-operator https://sap.github.io/sap-btp-service-operator

  4. Deploy the SAP BTP service operator in the cluster using the obtained access credentials:

    Note:
    If you are deploying the SAP BTP service operator in the registered cluster based on the Service Catalog (svcat) and Service Manager agent so that you can migrate svcat-based content to service operator-based content, add --set cluster.id=<clusterID> to your deployment script.
    For more information, see the step 2 of the Setup section of Migration to SAP BTP service operator.

    An example of the deployment that uses the default access credentials type:

    helm upgrade --install <release-name> sap-btp-operator/sap-btp-operator \
    --create-namespace \
    --namespace=sap-btp-operator \
    --set manager.secret.clientid=<clientid> \
    --set manager.secret.clientsecret=<clientsecret> \
    --set manager.secret.sm_url=<sm_url> \
    --set manager.secret.tokenurl=<auth_url>

    An example of the deployment that uses the X.509 certificate:

    helm upgrade --install <release-name> sap-btp-operator/sap-btp-operator \
    --create-namespace \
    --namespace=sap-btp-operator \
    --set manager.secret.clientid=<clientid> \
    --set manager.secret.tls.crt="$(cat /path/to/cert)" \
    --set manager.secret.tls.key="$(cat /path/to/key)" \
    --set manager.secret.sm_url=<sm_url> \
    --set manager.secret.tokenurl=<auth_url>

The credentials which are provided during the installation are stored in a secret named 'sap-btp-service-operator', in the 'sap-btp-operator' namespace. These credentials are used by the BTP service operator to communicate with the SAP BTP subaccount.

BTP Access Secret Structure

Default Access Credentials

apiVersion: v1
kind: Secret
metadata:
  name: sap-btp-service-operator
  namespace: sap-btp-operator
type: Opaque
stringData:
  clientid: "<clientid>"
  clientsecret: "<clientsecret>"
  sm_url: "<sm_url>"
  tokenurl: "<auth_url>"
  tokenurlsuffix: "/oauth/token"

mTLS Access Credentials

apiVersion: v1
kind: Secret
metadata:
  name: sap-btp-service-operator
  namespace: sap-btp-operator
type: Opaque
stringData:
  clientid: <clientid>
  tls.crt: <certificate>
  tls.key: <key>
  sm_url: <sm_url>
  tokenurl: <auth_url>
  tokenurlsuffix: "/oauth/token"

Note:
To rotate the credentials between the BTP service operator and Service Manager, you have to create a new binding for the service-operator-access service instance, and then to execute the setup script again, with the new set of credentials. Afterward, you can delete the old binding.

Managing Access

By default, the SAP BTP operator has cluster-wide permissions.
You can also limit them to one or more namespaces; for this, you need to set the following two helm parameters:

--set manager.allow_cluster_access=false
--set manager.allowed_namespaces={namespace1, namespace2..}

Note:
If allow_cluster_access is set to true, then allowed_namespaces parameter is ignored.

Working with Multiple Subaccounts

By default, a Kubernetes cluster is associated with a single subaccount (as described in step 4 of the Setup section). Consequently, any service instance created within any namespace will be provisioned in that subaccount.

However, the SAP BTP service operator also supports multi-subaccount configurations in a single cluster. This is achieved through:

  • Namespace-based mapping: Connect different namespaces to separate subaccounts. This approach leverages dedicated credentials configured for each namespace.

  • Explicit instance-level mapping: Define the specific subaccount for each service instance, regardless of the namespace context.

    Both can be achieved through dedicated secrets managed in the centrally managed namespace. Choosing the most suitable approach depends on your specific needs and application architecture.

Note: The system's centrally managed namespace is set by the value in .Values.manager.management_namespace. You can provide this value during installation (refer to step 4 in the Setup section). If you don't specify this value, the system will use the installation namespace as the default.

Subaccount For a Namespace

To associate a namespace to a specific subaccount you maintain the access credentials to the subaccount in a Secret that is dedicated to a specific namespace. Define a secret named: <namespace-name>-sap-btp-service-operator in the centrally-managed namespace.

Default Access Credentials

apiVersion: v1
kind: Secret
metadata:
  name: <namespace-name>-sap-btp-service-operator
  namespace: <centrally-managed-namespace>
type: Opaque
stringData:
  clientid: "<clientid>"
  clientsecret: "<clientsecret>"
  sm_url: "<sm_url>"
  tokenurl: "<auth_url>"
  tokenurlsuffix: "/oauth/token"

mTLS Access Credentials

apiVersion: v1
kind: Secret
metadata:
  name: <namespace-name>-sap-btp-service-operator
  namespace: <centrally-managed-namespace>
type: Opaque
stringData:
  clientid: <clientid>
  tls.crt: <certificate>
  tls.key: <key>
  sm_url: <sm_url>
  tokenurl: <auth_url>
  tokenurlsuffix: "/oauth/token"

Subaccount for a ServiceInstance Resource

You can deploy service instances belonging to different subaccounts within the same namespace. To achieve this, follow these steps:

  1. Store access credentials: Securely store the access credentials for each subaccount in separate Secret resources within the centrally-managed namespace.
  2. Specify subaccount per service: In the ServiceInstance resource, use the btpAccessCredentialsSecret property to reference the specific Secret containing the relevant subaccount's credentials. This explicitly tells the operator which subaccount to use to provision the service instance.

Define a new secret

Default Access Credentials

apiVersion: v1
kind: Secret
metadata:
  name: <my-secret>
  namespace: <centrally managed namespace>
type: Opaque
stringData:
  clientid: "<clientid>"
  clientsecret: "<clientsecret>"
  sm_url: "<sm_url>"
  tokenurl: "<auth_url>"
  tokenurlsuffix: "/oauth/token"

mTLS Access Credentials

apiVersion: v1
kind: Secret
metadata:
  name: <my-secret>
  namespace: <centrally managed namespace>
type: Opaque
stringData:
  clientid: <clientid>
  tls.crt: <certificate>
  tls.key: <key>
  sm_url: <sm_url>
  tokenurl: <auth_url>
  tokenurlsuffix: "/oauth/token"

Configure the secret name in the ServiceInstance resource within the property btpAccessCredentialsSecret:

The secret must be located in the management namespace

apiVersion: services.cloud.sap.com/v1
kind: ServiceInstance
metadata:
  name: sample-instance-1
spec:
  serviceOfferingName: service-manager
  servicePlanName: subaccount-audit
  btpAccessCredentialsSecret: mybtpsecret
Secrets Precedence

SAP BTP service operator searches for the credentials in the following order:

  1. Explicit secret defined in the ServiceInstance
  2. Default namespace secret
  3. Default cluster secret

Using the SAP BTP Service Operator

Service Instance

  1. To create an instance of a service offered by SAP BTP, first create a ServiceInstance custom-resource file:
    apiVersion: services.cloud.sap.com/v1
    kind: ServiceInstance
    metadata:
        name: my-service-instance
    spec:
        serviceOfferingName: sample-service
        servicePlanName: sample-plan
        externalName: my-service-btp-name
        parameters:
          key1: val1
          key2: val2

  • <offering> - The name of the SAP BTP service that you want to create. To learn more about viewing and managing the available services for your subaccount in the SAP BTP cockpit, see Service Marketplace.

    Tip: Use the Environment filter to get all offerings that are relevant for Kubernetes.

  • <plan> - The plan of the selected service offering you want to create.

  1. Apply the custom resource file in your cluster to create the instance.

    kubectl apply -f path/to/my-service-instance.yaml

  2. Check that the service's status in your cluster is Created.

    kubectl get serviceinstances
NAME                  OFFERING          PLAN        STATUS    AGE
my-service-instance   <offering>        <plan>      Created   44s

Back to top

Service Binding

To allow an application to obtain access credentials to communicate with a service, create a ServiceBinding custom resource. Set the serviceInstanceName field within the ServiceBinding to match the name of the ServiceInstance resource you previously created.

These access credentials are available to applications through a Secret resource generated in your cluster.

Structure of the ServiceBinding Custom Resource
apiVersion: services.cloud.sap.com/v1
kind: ServiceBinding
metadata:
  name: sample-binding
spec:
  serviceInstanceName: sample-instance
  externalName: my-binding-external
  secretName: my-secret
  parameters:
    key1: val1
    key2: val2

Procedure

  1. Apply the custom resource file in your cluster to create the ServiceBinding:

    kubectl apply -f path/to/my-binding.yaml

  2. Verify that your ServiceBinding status is Created before you proceed:

    kubectl get servicebindings
NAME         INSTANCE              STATUS    AGE
my-binding   my-service-instance   Created   16s

  3. Check that the Secret with the name as specified in the spec.secretName field of the ServiceBinding custom resource is created. Remember, the Secret contains access credentials needed for the apps to use the service:

    kubectl get secrets
NAME         TYPE     DATA   AGE
my-secret   Opaque   5      32s

    See Using Secrets to learn about different options on how to use the credentials from your application running in the Kubernetes cluster,

Formats of Service Binding Secrets

You can use different attributes in your ServiceBinding resource to generate different formats of your Secret resources.

Even though Secret resources can come in various formats, they all share a common basic content. The parameters within the Secret fall into two categories:

  • Credentials returned from the broker: These credentials allow your applications to access and consume the service.
  • Attributes of the associated ServiceInstance: This information provides details about the service instance itself.

Now let's explore these various formats:

Key-Value Pairs (Default)

If you do not use any of the attributes, the generated Secret will be in a key-value pair format.

ServiceBinding

apiVersion: services.cloud.sap.com/v1
kind: ServiceBinding
metadata:
  name: sample-binding
spec:
  serviceInstanceName: sample-instance

Secret

apiVersion: v1
metadata:
  name: sample-binding
kind: Secret
stringData:
  uri: https://my-service.authentication.eu10.hana.ondemand.com
  client_id: admin
  client_secret: ********
  instance_guid: your-sample-instance-guid // The service instance ID
  instance_name: sample-instance // Taken from the service instance external_name field if set. Otherwise from metadata.name
  plan: sample-plan // The service plan name                
  type: sample-service  // The service offering name
Credentials as JSON Object

To show credentials returned from the broker within the Secret resource as a JSON object, use the secretKey attribute in the ServiceBinding spec. The value of this secretKey is the name of the key that stores the credentials in JSON format:

ServiceBinding

apiVersion: services.cloud.sap.com/v1
kind: ServiceBinding
metadata:
  name: sample-binding
spec:
  serviceInstanceName: sample-instance
  secretKey: myCredentials

Secret

apiVersion: v1
kind: Secret
metadata:
  name: sample-binding
stringData:
    myCredentials:
      uri: https://my-service.authentication.eu10.hana.ondemand.com,
      client_id: admin,
      client_secret: ********
    instance_guid: your-sample-instance-guid // The service instance ID
    instance_name: sample-binding // Taken from the service instance external_name field if set. Otherwise from metadata.name 
    plan: sample-plan // The service plan name
    type: sample-service // The service offering name
Credentials and Service Info as One JSON Object

To show both credentials returned from the broker and additional ServiceInstance attributes as a JSON object, use the secretRootKey attribute in the ServiceBinding spec.

The value of secretRootKey is the name of the key that stores both credentials and ServiceInstance info in JSON format.

ServiceBinding

apiVersion: services.cloud.sap.com/v1
kind: ServiceBinding
metadata:
  name: sample-binding
spec:
  serviceInstanceName: sample-instance
  secretRootKey: myCredentialsAndInstance

Secret

apiVersion: v1
kind: Secret
metadata:
  name: sample-binding
stringData:
    myCredentialsAndInstance:
        uri: https://my-service.authentication.eu10.hana.ondemand.com,
        client_id: admin,
        client_secret: ********,
        instance_guid: your-sample-instance-guid, // The service instance id
        instance_name: sample-instance-name, // Taken from the service instance external_name field if set. Otherwise from metadata.name
        plan: sample-instance-plan, // The service plan name
        type: sample-instance-offering, // The service offering name
Custom Formats

For additional flexibility, you can model the Secret resources according to your needs.
To generate a custom-formatted Secret, use the secretTemplate attribute in the ServiceBinding spec.

This attribute expects a Go template as its value (for more information, see Go Templates).
Ensure the template is in YAML format, and its structure is of a Kubernetes Secret.

In the provided Secret, you can customize the metadata and stringData sections with the following options:

  • metadata: labels and annotations
  • stringData: customize or utilize one of the available formatting options as detailed in the Formats of Service Binding Secrets section.

Important: If you customize stringData, it takes precedence over the pre-defined formats (if you parallelly provided one of them).

Provided templates are then executed on a map with the following available attributes:

Reference Description
instance.instance_guid The service instance ID.
instance.instance_name The service instance name.
instance.plan The name of the service plan used to create this service instance.
instance.type The name of the associated service offering.
credentials.attributes(var) The content of the credentials depends on a service. For more details, refer to the documentation of the service you're using.

Below are two examples demonstrating 'ServiceBinding' and generated 'Secret' resources. The first ServiceBinding example utilizes a custom template, while the second example combines a custom template with a predefined formatting option:

Example of a binding with customized metadata and stringData sections

In this example, you specify both Metadata and stringData in the secretTemplate:

ServiceBinding

apiVersion: services.cloud.sap.com/v1
kind: ServiceBinding
metadata:
  name: sample-binding
spec:
  serviceInstanceName: sample-instance
  secretTemplate: |
    apiVersion: v1
    kind: Secret
    metadata:
      labels:
        service_plan: {{ .instance.plan }}
      annotations:
        instance: {{ .instance.instance_name }}
    stringData:
      USERNAME: {{ .credentials.client_id }}
      PASSWORD: {{ .credentials.client_secret }}

Secret

apiVersion: v1
kind: Secret
metadata:
  labels:
    service_plan: sample-plan
  annotations:
    instance: sample-instance
stringData:
  USERNAME: admin
  PASSWORD: ********
Example of a binding with customized metadata section and applied pre-existing formating option for stringData (credentials as JSON object):

In this example, you omit stringData from the secretTemplate and use the secretKey to format your stringData instead. (remember: Formats of Service Binding Secrets):

ServiceBinding

apiVersion: services.cloud.sap.com/v1
kind: ServiceBinding
metadata:
  name: sample-binding
spec:
  serviceInstanceName: sample-instance
  secretKey: myCredentials
  secretTemplate: |
    apiVersion: v1
    kind: Secret
    metadata:
      labels:
        service_plan: {{ .instance.plan }}
      annotations:
        instance: {{ .instance.instance_name }}

Secret

apiVersion: v1
kind: Secret
metadata:
  labels:
    service_plan: sample-plan
  annotations:
    instance: sample-instance
stringData:
  myCredentials:
    uri: https://my-service.authentication.eu10.hana.ondemand.com,
    client_id: admin,
    client_secret: ********
  instance_guid: your-sample-instance-guid // The service instance ID
  instance_name: sample-binding // Taken from the service instance external_name field if set. Otherwise from metadata.name
  plan: sample-plan // The service plan name
  type: sample-service // The service offering name

Service Binding Rotation

Enhance security by automatically rotating the credentials associated with your service bindings. This process involves generating a new service binding while keeping the old credentials active for a specified period to ensure a smooth transition.

Enabling Automatic Rotation

To enable automatic rotation of service bindings, use the credentialsRotationPolicy field within the spec section of the ServiceBinding resource. This field allows you to configure several parameters:

Parameter Type Description Valid Values
enabled bool Controls whether the automatic rotation is enabled or disabled.
rotationFrequency string Specifies the desired time interval between binding rotations. "m" (minute), "h" (hour)
rotatedBindingTTL string Determines how long to keep the old ServiceBinding resource after rotation (prior to deletion). The actual TTL may be slightly longer (details below). "m" (minute), "h" (hour)

Note that the credentialsRotationPolicy does not manage the validity or expiration of the credentials themselves. This is determined by the specific service you are bound to.

Rotation Process

The credentialsRotationPolicy is evaluated periodically during a control loop, which runs on every service binding update or during a full reconciliation process. This means the actual rotation will occur in the closest upcoming reconciliation loop.

Immediate Rotation

You can trigger an immediate rotation (regardless of the configured rotationFrequency) by adding the services.cloud.sap.com/forceRotate: "true" annotation to the ServiceBinding resource. This immediate rotation only works if automatic rotation is already enabled.

Example

This example configures a ServiceBinding to rotate credentials every 25 days (600 hours) and keep the old ServiceBinding for 2 days (48 hours) before deleting it:

apiVersion: services.cloud.sap.com/v1
kind: ServiceBinding
metadata:
  name: sample-binding
spec:
  serviceInstanceName: sample-instance
  credentialsRotationPolicy:
    enabled: true
    rotatedBindingTTL: 48h
    rotationFrequency: 600h

After Rotation

Once the ServiceBinding is rotated:

The Secret is updated with the latest credentials. The old credentials are kept in a newly-created secret named 'original-secret-name(variable)-guid(variable)'. This temporary secret is kept until the configured deletion time (TTL) expires.

Checking Last Rotation

To view the timestamp of the last service binding rotation, refer to the status.lastCredentialsRotationTime field.

Limitations

Automatic credential rotation cannot be enabled for a backup ServiceBinding (named: original-binding-name(variable)-guid(variable)) which is marked with the services.cloud.sap.com/stale label. This backup service binding was created during the credentials rotation process to facilitate the process.

Further Information

For more details about ServiceBinding, refer to the dedicated Service Binding section in this documentation.

Passing Parameters

To set input parameters, you may use the parameters and parametersFrom fields in the spec field of the ServiceInstance or ServiceBinding resource:

  • parameters: can be used to specify a set of properties to be sent to the broker. The data specified will be passed "as-is" to the broker without any modifications - aside from converting it to JSON for transmission to the broker in the case of the spec field being specified as YAML. Any valid YAML or JSON constructs are supported. Only one parameter field may be specified per spec.
  • parametersFrom: can be used to specify which secret, and key in that secret, which contains a string that represents the JSON to include in the set of parameters to be sent to the broker. The parametersFrom field is a list that supports multiple sources referenced per spec.

You may use either, or both, of these fields as needed.

If multiple sources in the parameters and parametersFrom blocks are specified, the final payload is a result of merging all of them at the top level. If there are any duplicate properties defined at the top level, the specification is considered to be invalid, the further processing of the ServiceInstance/ServiceBinding resource stops and its status is marked with an error condition.

The format of the spec in YAML

spec:
  ...
  parameters:
    name: value
  parametersFrom:
    - secretKeyRef:
        name: my-secret
        key: secret-parameter

The format of the spec in JSON

{
  "spec": {
    "parameters": {
      "name": "value"
    },
    "parametersFrom": {
      "secretKeyRef": {
        "name": "my-secret",
        "key": "secret-parameter"
      }
    }
  } 
}

The secret with the secret-parameter- named key:

apiVersion: v1
kind: Secret
metadata:
  name: my-secret
type: Opaque
stringData:
  secret-parameter:
    '{
      "password": "password"
    }'

The final JSON payload to send to the broker:

{
  "name": "value",
  "password": "password"
}

You can list multiple parameters in the secret. To do so, separate "key": "value" pairs with commas as in this example:

secret-parameter:
  '{
    "password": "password",
    "key2": "value2",
    "key3": "value3"
  }'

- Ready: set to true if the binding is ready and usable
- Failed: set to true when an operation on the service binding fails.
In the case of failure, the details about the error are available in the condition message.
- Succeeded: set to true when an operation on the service binding succeeded. In case of a false operation considered as in progress unless a Failed condition exists.
lastCredentialsRotationTime time Indicates the last time the binding secret was rotated.

Uninstalling the Operator

Before you uninstall the operator, we recommend you manually delete all associated service instances and bindings. This way, you'll ensure all data stored with service instances and bindings are properly taken care of. Instances and bindings that were not manually deleted will be automatically deleted once you start the uninstallation process.

To uninstall the operator, run the following command: helm uninstall <release name> -n <name space>

Example:

helm uninstall sap-btp-operator -n sap-btp-operator

Responses

  • release <release name> uninstalled - The operator has been successfully uninstalled

  • Timed out waiting for condition

    • What happened?

      The deletion of instances and bindings takes more than 5 minutes, this happens when there is a large number of instances and bindings.

    • What to do:

      Wait for the job to finish and re-trigger the uninstall process. To check the job status, run kubectl get jobs --namespace=<name space> or log on to the cluster and check the job log. Note that you may have to repeat this step several times untill the un-install process has been successfully completed.

  • job failed: BackoffLimitExceeded

    • What happened?

      One of the service instances or bindings could not be deleted.

    • What to do:

      First, locate the service instance or binding in question and fix it, then re-trigger the uninstallation.

      To find it, log on to the cluster and check the pre-delete job, or check the logs by running the following two commands:

      • kubectl get pods --all-namespaces| grep pre-delete - which gives you the list of all namespaces and jobs
      • kubectl logs <job_name> --namespace=<name_space_name> - where you specify the desired job and namespace

      Note that the pre-delete job is only visible for approximately one minute after the job execution is completed.   If you don't have access to the pre-delete job, use kubectl to view details about the failed resource and check its status by running:

      • kubectl describe <resource_type> <resource_name>

      Check for resources with the deletion timestamp to determine if it tried to be deleted.

Troubleshooting and Support

Cannot create a binding because service instance is in Delete Failed state

The deletion of my service instance failed. To fix the failure, I have to create a service binding, but I can't do that because the instance is in the Delete Failed state.

Solution

Use the force_k8s_binding query param when creating the service binding and set it to true (force_k8s_binding=true).You can do & this either with the Service Manager Control CLI (smctl) bind command.

Note:
Do not use the service-operator-access plan credentials to run this command.

smctl Example

smctl bind INSTANCE_NAME BINDING_NAME --param force_k8s_binding=true

Once you've finished working on the service instance, delete it by running the following command: 
smctl unbind INSTANCE_NAME BINDING_NAME --param force_k8s_binding=true

Note: force_k8s_binding is supported only for the Kubernetes instances that are in the Delete Failed state.

Cluster is unavailable and I still have service instances and bindings

I cannot delete service instances and bindings because the cluster in which they were created is no longer available.

Solution

Use a dedicated Service Manager API to clean up cluster content. Access the API with the subaccount-admin plan.
For more information, see Technical Access.

Note:
Do not call this API with the service-operator-access plan credentials.

Request

DELETE /v1/platforms/{platformID}/clusters/{clusterID}

Parameters

Parameter Type Description
platformID string The ID of the platform (should be the service-operator-access instance ID)
clusterID string The ID of the cluster. You should specify the ID from the step 4 of the Setup section. If you are unable to retrieve it, use the GET serrvice instance or binding API or equivalent btp CLI command and extract it from the response.

Response

Status Code Description
202 Accepted The request has been accepted for processing.

Headers:
'Location'- A path to the operation status, For more information about operations, see: Service Manager operation API.
404 Resource Not Found Platform or cluster not found
429 Too Many Requests When the rate limit is exceeded, the client receives the HTTP 429 "Too Many Requests" response status code.

Headers:
'Retry-After'- indicates the time in seconds after which the client can retry the request.

Attention: Use this option only for cleanup purposes for a cluster that's no longer available. Applying it to an active and available cluster may result in unintended resource leftovers in your cluster.

You're welcome to raise issues related to feature requests, or bugs, or give us general feedback on this project's GitHub Issues page. The SAP BTP service operator project maintainers will respond to the best of their abilities.

#-CR doesnt exist, ("instance" in Kuberbernetes) but it does exist on BTP. Once we create CR, it connects to the existing instance.* #- same name, namespace, Instance exists in BTP, not in Kubernetes cluster. How can we recover it? #- Create CR with the same name, namespace, and cluster ID (GET instance details, context in the response)* - separate PR
