Manual installation

Install the Operator manually

Note: If you are running on Google Kubernetes Engine (GKE), please check this first.

Register the Pravega cluster custom resource definition (CRD).

$ kubectl create -f deploy/crd.yaml

Create the operator role, role binding and service account.

$ kubectl create -f deploy/role.yaml
$ kubectl create -f deploy/role_binding.yaml
$ kubectl create -f deploy/service_account.yaml

Install the operator.

$ kubectl create -f deploy/operator.yaml

Set up Tier 2 Storage

Pravega requires a long term storage provider known as Tier 2 storage.

Check out the available options for Tier 2 and how to configure it.

In this example we are going to use a pravega-tier2 PVC using NFS as the storage backend.

Install the Pravega cluster manually

Once the operator is installed, you can use the following YAML template to install a small development Pravega Cluster (3 Bookies, 1 Controller, 3 Segment Stores). Create a pravega.yaml file with the following content.

apiVersion: "pravega.pravega.io/v1alpha1"
kind: "PravegaCluster"
metadata:
  name: "example"
spec:
  version: 0.4.0
  zookeeperUri: [ZOOKEEPER_HOST]:2181

  bookkeeper:
    replicas: 3
    image:
      repository: pravega/bookkeeper
    autoRecovery: true

  pravega:
    controllerReplicas: 1
    segmentStoreReplicas: 3
    image:
      repository: pravega/pravega
    tier2:
      filesystem:
        persistentVolumeClaim:
          claimName: pravega-tier2

where:

  • [ZOOKEEPER_HOST] is the host or IP address of your Zookeeper deployment.

Check out other sample CR files in the example directory.

Deploy the Pravega cluster.

$ kubectl create -f pravega.yaml

Verify that the cluster instances and its components are being created.

$ kubectl get PravegaCluster
NAME      VERSION   DESIRED MEMBERS   READY MEMBERS   AGE
example   0.4.0     7                 0               25s

Uninstall the Pravega cluster manually

$ kubectl delete -f pravega.yaml
$ kubectl delete pvc pravega-tier2

Uninstall the Operator manually

Note that the Pravega clusters managed by the Pravega operator will NOT be deleted even if the operator is uninstalled.

To delete all clusters, delete all cluster CR objects before uninstalling the operator.

$ kubectl delete -f deploy
