NFS Persistent Volumes

Do your pods need to have persitent volumes for your home Kubernetes cluster? Turns out, NFS is an option

Helm Charts

You can add the helm chart with:

helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/

Then always pull the values, since you will need to customize the NFS server IP and path

helm show values nfs-subdir-external-provisioner/nfs-subdir-external-provisioner > values.yaml

An example customized one looks like the following:

---
nfs:
  server: 192.168.2.70
  path: /srv/nfs/k8s
storageClass:
  create: true
  name: nfs-client
  defaultClass: true
tolerations:
  - key: "node-role.kubernetes.io/control-plane"
    operator: "Equal"
    effect: "NoSchedule"
affinity:
  nodeAffinity:
    requiredDuringSchedulingIgnoredDuringExecution:
      nodeSelectorTerms:
      - matchExpressions:
        - key: node-role.kubernetes.io/control-plane
          operator: Exists
resources:
  limits:
   cpu: 200m
   memory: 256Mi
  requests:
   cpu: 100m
   memory: 128Mi

And of course, we have to provision:

kubectl create namespace nfs-subdir
helm upgrade -i -f values.yaml nfs nfs-subdir-external-provisioner/nfs-subdir-external-provisioner --namespace nfs-subdir
