=== install ===

<code>
ubuntu@k0s-ctrl:~$ curl --proto '=https' --tlsv1.2 -sSf https://get.k0s.sh | sudo sh
ubuntu@k0s-ctrl:~$ k0s version
v1.31.1+k0s.1
</code>

Crea il servizio systemd:

<code>
ubuntu@k0s-ctrl:~$ sudo k0s install
</code>

=== Bootstrap controller ===

Bootstrap del nodo controller (non single mode)

<code>
ubuntu@k0s-ctrl:~$ sudo mkdir -p /etc/k0s
ubuntu@k0s-ctrl:~$ k0s config create | sudo tee /etc/k0s/k0s.yaml
ubuntu@k0s-ctrl:~$ sudo k0s install controller -c /etc/k0s/k0s.yaml
ubuntu@k0s-ctrl:~$ sudo systemctl start k0scontroller.service
</code>

Verifica:

<code>    
ubuntu@k0s-ctrl:~$ sudo k0s status
Version: v1.31.1+k0s.1
Process ID: 7885
Role: controller
Workloads: false
SingleNode: false
</code>

=== Ambiente di lavoro ===

Per rendere più comoda la gestione:

<code>
ubuntu@k0s-ctrl:~$ mkdir -p .config/k0s
ubuntu@k0s-ctrl:~$ sudo k0s kubeconfig admin | tee  ~/.config/k0s/admin.conf
ubuntu@k0s-ctrl:~$ echo "alias kubectl='k0s kubectl --kubeconfig="$HOME"/.config/k0s/admin.conf'" >>  ~/.bash_aliases
</code>

=== creazione worker ===

Sul controller creare un token (si può redirigere su file)

<code>
ubuntu@k0s-ctrl:~$ sudo k0s token create --role=worker --expiry=100h 
</code>

Sul candidato nodo installare k0s con curl (vedi sopra) e copiare il token generato nel controller in un file (es k8s_worker_token)

<code>
ubuntu@a6:~$ sudo k0s install worker --token-file  ./k8s_worker_token
ubuntu@a6:~$ sudo k0s start
<(code>

Verificare il successo dell'operazione sul controller 

<code>
ubuntu@k0s-ctrl:~$ kubectl get node
NAME   STATUS   ROLES    AGE    VERSION
a6     Ready    <none>   4m6s   v1.31.1+k0s
</code>

k0s incorpora ''kubectl'', che fa prefissato da ''k0s''. Esempio:

<code>
ubuntu@k0s-ctrl:~$ sudo k0s kubectl cluster-info
</code>
