Deploy on Red Hat Openshift

Red Hat OpenShift is an enterprise-ready Kubernetes container platform built for an open hybrid cloud strategy, It provides a consistent application platform to manage hybrid cloud, multicloud, and edge deployments. StreamNative Private Cloud has supported to deploy and manage on the OpenShift platform, this page describes step-by-step installation.

Install StreamNative Operator

StreamNative Operator has certified as Red Hat OpenShift Operators, so users can easily install the sn-operator through the OpenShift Web Console.

Navigate to OperatorHub page and search for sn-operator.
Click the “Install” button and wait for the operator installation.
Navigate to the Secret page and switch to openshift-operators project.
Create the secret yaml with license token, you can refer the licenses for more details.

Create Security Context Constraint (SCC)

Before provision the Pulsar cluster, you need to configure the Security Context Constraints.

Navigate to API Explorer page and shift to the SecurityContextConstraints API

Create the SCC with below configuration:

apiVersion: security.openshift.io/v1
kind: SecurityContextConstraints
metadata:
  name: private-cloud-scc
allowHostDirVolumePlugin: false
allowHostIPC: false
allowHostNetwork: false
allowHostPID: false
allowHostPorts: false
allowPrivilegeEscalation: true
allowPrivilegedContainer: true
defaultAddCapabilities: null
fsGroup:
  type: RunAsAny
groups:
  - system:authenticated
priority: null
readOnlyRootFilesystem: false
requiredDropCapabilities: null
runAsUser:
  type: RunAsAny
seLinuxContext:
  type: RunAsAny
seccompProfiles:
  - '*'
supplementalGroups:
  type: RunAsAny
users: []
volumes:
  - configMap
  - downwardAPI
  - emptyDir
  - persistentVolumeClaim
  - projected
  - secret

Provision Pulsar cluster

After creating the SCC, we can start provisioning the Pulsar cluster.

Navigate to the Project page and create a new project called “Pulsar”

Get into the Pulsar project and choose a metadata store.

ZooKeeper
Oxia

The default deployment uses ZooKeeperCluster for Pulsar metadata.

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

Oxia is an experimental metadata-store alternative for supported Private Cloud releases. If your deployment plan requires Oxia, use the same OpenShift project and SCC flow with an Oxia-backed Pulsar cluster manifest.

oc apply -f https://raw.githubusercontent.com/streamnative/private-cloud/main/oxia/pulsar-oxia.yaml

For Oxia resource configuration details, see Configure Oxia.

Wait for Pods up and running.
