* Personalisez votre simulateur avec la commande (au besoin ajustez la mémoire et les cpus utilisés dans Vagrantfile) :
```bash
vagrant plugin install vagrant-disksize
vagrant plugin install vagrant-vbguest
./init.sh # vous pouvez laisser les choix par défaut
```
* (Optionnel) Ajustez éventuellement la mémoire et les cpus utilisés dans Vagrantfile (par défaut 4GB et 2 vCPUs)
* Pour créer tout l'univers Kaz il faut se placer dans le répertoire et lancer la commande :
```bash
vagrant up
```

Cette étape peut-être (très) longue. Notamment, la construction de kaz-prod se fait dans un conteneur LXC, dans lequel les overlays docker passent par un filesystem plus lent qu'en natif... Comptez entre 40 minutes et quelques heures, selon la connexion réseau et les performances de la machine.
