-# Bad Ideas
+# NFS
 
-Amabassador: (for knative)
+Server: CentOS 9
+Set up:
+```
+sudo dnf install nfs-utils vim
+sudo mkdir /srv/nfs
+sudo chown jimmy:jimmy /srv/nfs
+sudo chmod 777 /srv/nfs/
+```
+Put into `/etc/exports`:
+```
+/srv/nfs    192.168.1.0/24(rw,root_squash)
+```
+Start everything:
+```
+systemctl enable --now rpcbind
+systemctl enable --now nfs-server
+firewall-cmd --permanent --add-service nfs
+firewall-cmd --reload
+systemctl restart nfs-server
+```
 
-Start with these instruction to disable traefik.
-https://www.suse.com/c/rancher_blog/deploy-an-ingress-controller-on-k3s/
-use `--disable=traefik` in systemd.
-The equal is important...
+Test on Debian:
+```
+sudo apt install nfs-common
+sudo mkdir -p /mnt/nfs
+sudo mount 192.168.1.149:/srv/nfs /mnt/nfs
+```
 
-Follow the instructions https://www.getambassador.io/docs/edge-stack/latest/topics/install/yaml-install/ to install ambassador.
-
-I used the file in ./ambassador/listener.yaml to set up the listener.
-
-I'm not sure why ambassdor is listening on 80 instead of 8080 given the
-settings I applied, or why changing from 8080 to 80 in the seeting borks
-it.
-
-I removed amabassador andput back traefik.
+On the k3s nodes:
+```
+sudo apt install nfs-common
+```
 
+Install to the cluster:
+```
+helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/
+helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
+  --set nfs.server=192.168.1.149 \
+  --set nfs.path=/srv/nfs
+```
 
+# Future Ideas
 
 If we later want to do this on an overlay network:
 3. For master:
    `INSTALL_K3S_EXEC="server --node-ip '10.100.100.5' --advertise-address '10.100.100.5' --flannel-iface 'wg0'" ./k3s.sh`
 4. For node:
    `INSTALL_K3S_EXEC="agent --server 'https://10.100.100.5:6443' --token 'K3S_TOKEN' --node-ip '10.100.100.?' --advertise-address '10.100.100.?' --flannel-iface 'wg0'" ./k3s.sh`
-For now sticking to single node...
-
-Set up a namespace:
-```
-kubectl create -f j7s-dev-namspace.json
-```
-```
-kubectl config set-context j7s-dev --namespace=j7s-dev \
-  --cluster=j7s-dev \
-  --user=default
-```
-I'm not sure the above command works...
