+# f3s: Kubernetes with FreeBSD - Part 6: Storage
+
+> Published at 2025-07-13T16:44:29+03:00
+
+This is the seventh blog post about the f3s series for self-hosting demands in a home lab. f3s? The "f" stands for FreeBSD, and the "3s" stands for k3s, the Kubernetes distribution used on FreeBSD-based physical machines.

+## Introduction
+
+## Updating
+
+On all three Rocky Linux 9 boxes `r0`, `r1`, and `r2`:
+
+```sh
+dnf update -y
+reboot
+```
+
+On the FreeBSD hosts, upgrading from FreeBSD 14.2 to 14.3-RELEASE, running this on all three hosts `f0`, `f1` and `f2`:
+
+```sh
+paul@f0:~ % doas freebsd-update fetch
+paul@f0:~ % doas freebsd-update install
+paul@f0:~ % doas reboot
+.
+.
+.
+paul@f0:~ % doas freebsd-update -r 14.3-RELEASE upgrade
+paul@f0:~ % doas freebsd-update install
+paul@f0:~ % doas freebsd-update install
+paul@f0:~ % doas reboot
+.
+.
+.
+paul@f0:~ % doas freebsd-update install
+paul@f0:~ % doas pkg update
+paul@f0:~ % doas pkg upgrade
+paul@f0:~ % doas reboot
+.
+.
+.
+paul@f0:~ % uname -a
+FreeBSD f0.lan.buetow.org 14.3-RELEASE FreeBSD 14.3-RELEASE
+        releng/14.3-n271432-8c9ce319fef7 GENERIC amd64
+```
+
+## Installing k3s
+
+Generating the k3s token on my Fedora Laptop with `pwgen -n 32` and selected one. And then on all 3 `r` hosts (replace SECRET_TOKEN with the actual secret!! before running the following command) run:
+
+```sh
+[root@r0 ~]# echo -n SECRET_TOKEN > ~/.k3s_token
+```
+
+The following steps are also documented on the k3s website:
+
+=> https://docs.k3s.io/datastore/ha-embedded
+
+So on `r0` we run:
+
+```sh
+[root@r0 ~]# curl -sfL https://get.k3s.io | K3S_TOKEN=$(cat ~/.k3s_token) \
+        sh -s - server --cluster-init --tls-san=r0.wg0.wan.buetow.org
+[INFO]  Finding release for channel stable
+[INFO]  Using v1.32.6+k3s1 as release
+.
+.
+.
+[INFO]  systemd: Starting k3s
+```
+
+And we run on the other two nodes `r1` and `r2`:
+
+```sh
+[root@r1 ~]# curl -sfL https://get.k3s.io | K3S_TOKEN=$(cat ~/.k3s_token) \
+        sh -s - server --server https://r0.wg0.wan.buetow.org:6443 \
+        --tls-san=r1.wg0.wan.buetow.org
+
+[root@r2 ~]# curl -sfL https://get.k3s.io | K3S_TOKEN=$(cat ~/.k3s_token) \
+        sh -s - server --server https://r0.wg0.wan.buetow.org:6443 \
+        --tls-san=r2.wg0.wan.buetow.org
+.
+.
+.
+
+```
+
+Once done, we've got a 3 node Kubernetes cluster control plane:
+
+```sh
+[root@r0 ~]# kubectl get nodes
+NAME                STATUS   ROLES                       AGE     VERSION
+r0.lan.buetow.org   Ready    control-plane,etcd,master   4m44s   v1.32.6+k3s1
+r1.lan.buetow.org   Ready    control-plane,etcd,master   3m13s   v1.32.6+k3s1
+r2.lan.buetow.org   Ready    control-plane,etcd,master   30s     v1.32.6+k3s1
+```
