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 create workloads through yaml manifests.
