+title:  "Enable NFS on K3S"
+date:   2021-12-26
+tags: ['kubernetes', 'linux', 'helm', 'k3s']
+---
+
+By default [[https://k3s.io/][K3S]] comes only with [[https://github.com/rancher/local-path-provisioner][local-path]] storage class, and if you are running
+with more than one node in your cluster you may want to use a more "distributed"
+solution. For may case I opted for NFS.
+
+To check the current storage class you can run:
+
+#+BEGIN_SRC bash
+k3s kubectl get storageclasses
+#+END_SRC
+
+And it will print something like:
+
+#+BEGIN_SRC
+NAME                   PROVISIONER                                     RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
+local-path (default)   rancher.io/local-path                           Delete          WaitForFirstConsumer   false                  154d
+#+END_SRC
+
+To start adding First you need to install [[https://github.com/helm/helm][helm]] on your server. To do so you may
+run:
+
+#+BEGIN_SRC bash
+curl -sSL https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3 | bash
+#+END_SRC
+
+*Be careful when running scripts directly into bash always check the source*
+*Sometimes is also recommended to do not pipe directly to bash*
+
+Once it is installed we need to add the [[https://kubernetes.io/docs/concepts/storage/storage-classes/#nfs][NFS storage classes]]. It has two
+providers, I have chose [[https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner][NFS Subdir External Provisioner]].
+
+Add the helm repo
+
+#+BEGIN_SRC bash
+helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/
+#+END_SRC
+
+Then we need to actually install the provider
+
+
+#+BEGIN_SRC bash
+helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
+    --set nfs.server=x.x.x.x \
+    --set nfs.path=/exported/path
+#+END_SRC
+
+Set the ~nfs.server~ and ~nfs.path~ accordingly with your setup.
+
+After that if we run ~k3s kubectl get storageclasses~ it will now print another
+NFS provider:
+
+#+BEGIN_SRC
+NAME                   PROVISIONER                                     RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
+local-path (default)   rancher.io/local-path                           Delete          WaitForFirstConsumer   false                  154d
+nfs-client             cluster.local/nfs-subdir-external-provisioner   Delete          Immediate              true                   76m
+#+END_SRC
