3. Deploy PortWorx storage in kubernetes

Specification : Kubernetes, PortWorx, Storage

PortWorx storage cluster

Portworx by Pure Storage is a cloud native storage solution, provides a fully integrated solution for persistent storage, data protection, disaster recovery, data security, cross-cloud and data migrations, and automated capacity management for applications running on Kubernetes. If you see in each of documents, portworx have big IOPS & Bandwidth.

Lab Topology

First, make your k8s cluster already running

If your cluster ready, you can check in previous docummentation for installation https://assyafii.com/docs/install-kubernetes-cluster-multi-master-ha/

Add labels px/metadata-node=true for portworx nodes

kubectl label nodes sf-k8s-portworx-1 sf-k8s-portworx-2 px/metadata-node=true

Create portworx template generator

1. Login to https://central.portworx.com/specGen/wizard & choose version

2. Checklist use operator

3. You need configure KVDB Devices if production, for testing skip this

4. Skip network configuration

5. Add cluster name prefix

6. Apply deployment to cluster from template created

Verification

Checks status POD portworx running

kubectl get pods -n kube-system

If running all, check cluster portworx

PX_POD=$(kubectl get pods -l name=portworx -n kube-system -o jsonpath='{.items[0].metadata.name}')
kubectl exec -it $PX_POD -n kube-system -- /opt/pwx/bin/pxctl status

Testing scenario

For test, wee will deploy POD FIO then benchmark on directory which mount to portworx cluster.

Create PVC & POD For testing

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: px-pvc-fio
spec:
  accessModes:
    - ReadWriteOnce
  volumeMode: Filesystem
  resources:
    requests:
      storage: 20Gi
  storageClassName: px-replicated
---
apiVersion: v1
kind: Pod
metadata:
  name: px-pod-fio
spec:
  containers:
    - name: fio
      image: vineethac/fio_image
      command: [ "/bin/bash", "-c", "--" ]
      args: [ "while true; do sleep 30; done;" ]
      imagePullPolicy: IfNotPresent
      volumeMounts:
        - mountPath: "/mnt/px"
          name: px-pvc-fio-vol
  volumes:
    - name: px-pvc-fio-vol
      persistentVolumeClaim:
        claimName: px-pvc-fio

FIO Testing in directory /mnt/px
