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

​
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 Private Cloud architecture
  • 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” Private Cloud architecture
  • Get into the Pulsar project and create workloads through yaml manifests.
