Step-by-Step: Adding NFS Storage to Your Kubernetes Cluster

#kubernetes #microk8s #homeserver #synology In this video, we'll show you how to expand the capabilities of a Kubernetes cluster by adding shared storage. We'll be upgrading a home cluster by connecting a Synology NAS as an NFS server that can serve read-write-many persistent volumes. But before we get into the demo, we'll explain why you would want to do this and the downsides of sticking with the default storage that comes with a Kubernetes cluster. Kubernetes running on nodes are really designed to provide only compute resources. This means that if your compute workload needs to store things to a disk for anything other than temporary usage, it’ll need some place else to store that data. On Kubernetes, that means declaring persistent volumes in the definition of your app. The issue though, that we start to run into immediately is the location and the availability of those requested storage volumes. In this video, we'll show you how to solve this problem using the Kubernetes NFS provisioner (or NFS container storage interface). NFS servers have been around for forever and have provided a simple way for multiple workloads to connect to one disk. It even allows both workloads to read and write simultaneously. The NFS CSI allows a multi-node Kubernetes cluster to create and mount volumes that are backed by NFS. Installing and configuring the CSI is a one-time thing and after that, it's completely transparent to users of the cluster. We'll walk you through the steps and show you how to set up a Kubernetes cluster to use NFS for provisioning volumes. The very first thing we need to do is have an NFS server. There are a bunch of ways to do this, and we'll show you two of them - adding NFS to one of your Kubernetes nodes or using a separate device for running NFS. Follow along with us as we demonstrate how to set up a Kubernetes cluster with shared storage, allowing for greater flexibility and scalability in your workloads.
