​
Prerequisites

To use StreamNative Private Cloud, the following are required:

  • Prepare a Kubernetes cluster (Kubernetes version >= 1.16).
  • Install kubectl (v1.16 or above), compatible with your cluster (+/- 1 minor release from your cluster).
  • Install Helm (v3.0.2 or above).

​
Create the operators namespace

  1. Create a Kubernetes namespace where the operator will be installed later.

    kubectl create namespace operators

​
Install StreamNative Private Cloud

​
Import license

Before installing 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 contact StreamNative to apply for a free trial.

When you have a license in hand, you can import it through:

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.

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Secret
metadata:
# This label is a required field for the sn-operator to detect the license.
  labels:
    cloud.streamnative.io/type: "license"
  name: sn-license
  namespace: operators
type: Opaque
stringData:
  license: "Your license token"
EOF

​
Install the StreamNative Operator

  1. Add the StreamNative chart repository.

    helm repo add streamnative https://charts.streamnative.io
helm repo update

  2. Deploy the StreamNative Operator using the sn-operator Helm chart in the created Kubernetes namespace.

    helm install sn-operator streamnative/sn-operator -n operators

  3. Verify that Operator Pods are running.

    kubectl get all -n operators

​
Create the Pulsar namespaces

Create the namespaces pulsar. The pulsar namespace is used for deploying your Pulsar cluster.

kubectl create ns pulsar

​
Provision a Pulsar cluster

To provision a Pulsar cluster through the StreamNative Operator, you need to define a YAML file for your Pulsar cluster.

Run the command below to deploy your Pulsar cluster in pulsar namespace

kubectl apply -f https://raw.githubusercontent.com/streamnative/private-cloud/main/quick-start/pulsar-cluster.yaml

​
Tools usage

StreamNative Private Cloud provisions a toolset Pod which packages regual Pulsar tools:

kubectl exec -it private-cloud-toolset-0 -n pulsar -- bash

Use pulsar-client to quickly produce some messages

bin/pulsar-client produce private-cloud -m "sn-private-cloud" -n 10

2023-10-21T20:39:58,509+0000 [main] INFO  org.apache.pulsar.client.cli.PulsarClientTool - 10 messages successfully produced

Use pulsarctl to check the resource status

bin/pulsarctl topics list public/default

​
Access to Console

kubectl port-forward console-streamnative-console-0 9527:9527 -n pulsar

​
Clean up

Run the command below to delete your Pulsar cluster.

kubectl delete -f https://raw.githubusercontent.com/streamnative/private-cloud/main/quick-start/pulsar-cluster.yaml

Run the command below to remove the sn-operator.

helm uninstall sn-operator -n operators
