Install the Pulsar Operators using the Operator Lifecycle Manager

​

Prerequisites

• Prepare a Kubernetes cluster (v1.24 or above)
• Install kubectl (v1.24 or above), compatible with your cluster (+/- 1 minor release from your cluster).

​

Install the Pulsar Operators

1. Install the OLM. The script automatically creates the olm namespace and the operators namespace.
   curl -sL https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.23.1/install.sh | bash -s v0.23.1
   
2. Install the Custom Resource Definitions (CRDs) and custom controllers for Pulsar, BookKeeper, and ZooKeeper. The controllers are deployed in the operators namespace by default.
   kubectl create -f https://raw.githubusercontent.com/streamnative/charts/master/examples/pulsar-operators/olm-subscription.yaml
   
3. Verify that the Pulsar Operators are installed successfully.
   kubectl get all -n operators

4. View the created CRDs. These CRDs can be used to create CRs for Pulsar.
   kubectl get crds | grep streamnative
   
   You should see the following output:
   NAME                                            CREATED AT
   bookkeeperclusters.bookkeeper.streamnative.io   2023-03-02T08:52:52Z
   pulsarbrokers.pulsar.streamnative.io            2023-03-02T08:52:52Z
   pulsarproxies.pulsar.streamnative.io            2023-03-02T08:52:52Z
   zookeeperclusters.zookeeper.streamnative.io     2023-03-02T08:52:53Z
   
5. View the ClusterServiceVersion (CSV) of these operators.
   kubectl get csv -n operators
   
   You should see the following output:
   NAME                          DISPLAY               VERSION   REPLACES                      PHASE
   bookkeeper-operator.v0.14.1   BookKeeper Operator   0.14.1    bookkeeper-operator.v0.12.4   Succeeded
   pulsar-operator.v0.14.1       Pulsar Operator       0.14.1    pulsar-operator.v0.12.4       Succeeded
   zookeeper-operator.v0.14.1    ZooKeeper Operator    0.14.1    zookeeper-operator.v0.12.4    Succeeded
   
   With the Pulsar Operators installed, you can use the controllers and the CRDs to deploy a Pulsar cluster.
