Kuberbetes persistent volume test

This repository contains read/write speed tests for Kubernetes Persistent Volumes (PVs). This repo is a clone from "https://github.com/phnmnl/k8s-volume-test" and make tiny modification

How to run the test

Prerequisites

We assume you have:

• A Kubernetes cluster up and running with configured kubectl CLI
• A PV that supports ReadWriteMany with at least 5GB of capacity

Running the tests

Please clone this repository, and locate into it:

cd k8s-volume-test

Create a "LocalStorage" PersistentVolume using pv.yml:

kubectl apply -f pv.yml

Create a PersistentVolumeClaim using pvc.yml:

kubectl apply -f pvc.yml

Perform the write test:

kubectl apply -f write.yml

Check the write test STATUS, and wait until it is Completed:

kubectl get pods --show-all

Get the output of the writing test:

kubectl logs $(kubectl get pods --show-all -o jsonpath='{.items[?(@.spec.containers[*].name=="write")].metadata.name}')

Perform the read test:

kubectl apply -f read.yml

Check the write test STATUS, and wait until it is Completed:

kubectl get pods --show-all

Get the output of the reading test:

kubectl logs $(kubectl get pods --show-all -o jsonpath='{.items[?(@.spec.containers[*].name=="read")].metadata.name}')
