Deployment

Deploying Pravega manually on Kubernetes:

 

1) Install Bookkeeper

 

helm install bookkeeper-operator charts/bookkeeper-operator

Verify that the Bookkeeper Operator is running.

 

$ kubectl get deploy

NAME                          DESIRED   CURRENT   UP-TO-DATE   AVAILABLE     AGE

bookkeeper-operator              1         1         1            1          17s

Install the Operator in Test Mode

The Operator can be run in test mode if we want to deploy the Bookkeeper Cluster on minikube or on a cluster with very limited resources by setting testmode: true in values.yaml file. Operator running in test mode skips the minimum replica requirement checks. Test mode provides a bare minimum setup and is not recommended to be used in production environments.

 

2) Install the zookeeper:

 

helm install zookeeper-operator charts/zookkeeper-operator

Verify that the zookeeper Operator is running.

 

$ kubectl get deploy

NAME                 DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE

zookeeper-operator   1         1         1            1           12s

 

3) Install Pravega

 

Install the Operator

 

Deploying in Test Mode

The Operator can be run in a "test" mode if we want to create pravega on minikube or on a cluster with very limited resources by enabling testmode: true in values.yaml file. Operator running in test mode skips minimum replica requirement checks on Pravega components. "Test" mode ensures a bare minimum setup of pravega and is not recommended to be used in production environments.

 Using the testmode we can even specify a custom pravega version that can be skipped from the validations of the webhook.

 

Install a sample Pravega cluster

Set up Tier 2 Storage

Pravega requires a long term storage provider known as longtermStorage.

 

Check out the available options for long term storage and how to configure it.

 

For demo purposes, an NFS server can be installed. 

 

$ helm install stable/nfs-server-provisioner --generate-name

 

helm install pravega-operator charts/pravega-operator

Verify that the pravega Operator is running.

 

$ kubectl get deploy

NAME                 DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE

pravega-operator   1         1         1            1           13s

Please note that the Kubernetes mode differs from the manual steps for VM mode installation in the provisioning of K8s services
