Starting March 31st, 2024, access to the StreamNative Pulsar distribution will require a valid StreamNative subscription. As a result, StreamNative Pulsar images such as streamnative/private-cloud, streamnative/sn-platform and streamnative/sn-platform-slim will require a license key to run; otherwise, the component will fail to start.
Provision Pulsar cluster with PulsarCoordinator object doesn’t need to configure license for StreamNative docker images, sn-operator will issue the valid license for images after detecting the PulsarCoordinator object. For some cases you can’t use the PulsarCoordinator object, you can directly configure license for docker images.

​
Import license

If you do not have any license, you can contact StreamNative to apply for a free trial. When you have a license in hand, you can import it through: 
cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Secret
metadata:
  labels:
    cloud.streamnative.io/type: "license"
  name: sn-license
  namespace: "the Kubernetes namespace you will install the StreamNative Pulsar Cluster"
type: Opaque
stringData:
  license: "Your license token"
EOF

​
Configure image license with sn-operator

If you already installed the sn-operator, you can configure the license Secret on the spec.pod.secretRefs field: 
spec:
  pod:
    secretRefs:
    - mountPath: /mnt/sn-license
      secretName: "sn-license"

​
Configure image license without sn-operator

If you don’t install the sn-operator, we can configure liense secret on broker StatefulSet。 On the broker’s StatefulSet object, add the license Secret by 
apiVersion: apps/v1
kind: StatefulSet
spec:
  template:
    spec:
      containers:
        name: pulsar-broker
        volumeMounts:
        - mountPath: /mnt/sn-license
          name: secret-sn-license
          readOnly: true
      volumes:
      - name: secret-sn-license
        secret:
          defaultMode: 420
          secretName: sn-license
