Veritas InfoScale™ for Kubernetes Environments 8.0.200 - Linux

Last Published: 2023-02-21

Product(s): InfoScale & Storage Foundation (8.0.200)

Platform: Linux

Tech Preview: Installing InfoScale on an Azure Kubernetes Service(AKS) cluster

Prerequisites

Azure Kubernetes Service (AKS) cluster must be created by using the manual scaling method and the cluster must be running.

Note:

Do not power off the Azure Kubernetes Service(AKS) cluster after provisioning storage.

Run the command kubectl get nodes to verify whether all nodes are ready and running.

NAME                             STATUS ROLE   AGE  VERSION
<Name of the first worker node>  Ready  agent  6h3m v1.23.8
<Name of the second worker node> Ready  agent  6h3m v1.23.8

.
.

Copy the following content and save the file as storage-provision.yaml. Ensure that you specify replicas, storageClassName, and storage for the cluster.

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: storage
  labels:
    app: infoscale
  annotations:
    specialresource.openshift.io/wait: "true"

  podManagementPolicy: "Parallel"
  serviceName: "provisioner"
  replicas: <Number of worker nodes in the cluster
             You can specify upto 16 nodes>

        requests:
          storage: <Storage capacity per node in GB>
---

Run the following command to assign storage to the worker nodes.
kubectl apply -f storage-provision.yaml
Following output indicates that storage is assigned.
```
statefulset.apps/storage created
```

Run the following command to verify whether pods are created successfully in the namespace where you applied the yaml.

kubectl get pods

Output similar to the following indicates a successful creation of pods.

default   storage-0  1/1     Running    0  22h
default   storage-1  1/1     Running    0  22h
default   storage-2  1/1     Running    0  22h
default   storage-3  1/1     Running    0  22h
default   storage-4  1/1     Running    0  22h

Note:
excludeDevice, Encryption, and fencingDevice are not supported for AKS. While configuring cr.yaml, ensure that you do not enter these parameters.
