Скачать или смотреть [05] Kubernetes - Deploying a dynamic NFS provisioner

Description:
In this video we will setup an Network File Share dynamic storage provisioner for our Kubernetes cluster. We will use a helm chart, download and configure the values file and
deploy this provisioner. We will test the solution by creating a persistent volume claim and adding a pod which will write a file to this storage.
