+# Playbooks
+
+Qui vengono riportati i playbook disponibili, descrizione e utilizzo. 
+**NB** Ci si aspetta che i playbook siano idempotenti. In caso contrario e' importante riportarlo nella documentazione corrente. 
+
+### Bootstrap
+Implementa la configurazione di base di un nodo per poter essere gestito dagli altri playbook, in particolare : 
+- crea l'utente ansible
+- registra le chiavi ssh degli utenti configurati
+
+
+
+#### Parametri
+Il playbook si aspetta le seguenti variabili
+```
+ansible_authorized_keys:
+	- label : <MY LABEL>
+	  key: <MY>
+```
+
+
+#### Chiamata
+Per lanciare il playbook e' necessario specificare l'utente da utilizzare per connettersi ed esguire il playbook con l'opzione *-e*'.
+L'opzione '*-K*' invece permette di chiedere la password dell'utente remoto 
+
+```
+ ansible-playbook -i inventories/<INVENTORY>.yaml  playbooks/bootstrap.yaml -e 'ansible_user=<SUDO USER>' -K
+```
+
+### VPN Server
