Configure license for StreamNative images

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 licnese 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 licnese 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
