This page introduces how to configure and manage the license in the StreamNative Private Cloud. Before installing the StreamNative Private Cloud, you need to import a valid license. Otherwise, StreamNative Private Cloud will stop reconciling with a “no valid license” error message: 
ERROR	controller.pulsarcoordinator	Reconciler error	{"reconciler group": "k8s.streamnative.io", "reconciler kind": "PulsarCoordinator", "name": "private-cloud", "namespace": "pulsar", "error": "No valid license has been found under namespace operators, please contact https://streamnative.io/deployment/start-free-trial"}
sigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).processNextWorkItem
If you do not have any license, you can apply for a trial from https://streamnative.io/deployment/start-free-trial.

​
Import a license

StreamNative Private Cloud provides a license using the Kubernetes Secret. To import a license, follow these steps:
  1. Get a license token from StreamNative.
  2. Define a license manifest like the example below:
metadata.labels with the cloud.streamnative.io/type: "license" is required because the sn-operator will detect secrets in its namespace with label and to import automatically.
apiVersion: v1
kind: Secret
metadata:
  labels:
    cloud.streamnative.io/type: "license"
  name: sn-license
  namespace: "the Kubernetes namespace you will install the StreamNative Operator"
type: Opaque
stringData:
  license: "Your license token"
  1. Run the following command to import your license.
kubectl apply -f <your-license-secret-file>

​
Update a license

Before your current license expires, you need to contact the StreamNative to get a new one. To update the license, you need to import the new license as a new Kubernetes Secret with a different secret name in the same namespace. StreamNative Private Cloud Operators will automatically detect the new Secret and adopt the new license.

​
View license status and resource utilization

StreamNative Private Cloud Operators maintain and store the license status and resource usage data to a Kubernetes ConfigMap named sn-valid-license. By default, the ConfigMap is stored in the namespace where StreamNative Private Cloud Operators are installed. Run the command below to view the license status and resource utilization. 
kubectl get configmap sn-private-cloud-license -n operators -o json | jq .data
