# cubic-linuxmint
|
||||
|
||||
Préparation d'une image iso personnalisée pour l'installation de postes Linux Mint par Libretic.
|
||||
|
||||
Le but de cette image est de proposer une image iso amorçable, permettant d'installer rapidement des
|
||||
ordinateurs basés sur Linux Mint et équipés d'un minimum de logiciels et de configuration.
|
||||
|
||||
|
||||
## Création de l'image iso
|
||||
|
||||
* Sur un poste linux-mint, installer le logiciel [Cubic](https://github.com/PJ-Singh-001/Cubic) :
|
||||
|
||||
```bash
|
||||
sudo apt-add-repository universe
|
||||
sudo apt-add-repository ppa:cubic-wizard/release
|
||||
sudo apt update
|
||||
sudo apt install --no-install-recommends cubic
|
||||
```
|
||||
|
||||
* Télécharger l'image linux mint officielle (édition cinnamon)
|
||||
|
||||
* Cloner ce pojet
|
||||
|
||||
```bash
|
||||
git clone https://git.libretic.fr/libretic/cubic-linuxmint.git
|
||||
```
|
||||
|
||||
* Adapter le projet selon ses besoins, notamment :
|
||||
* `vars/main.yml`
|
||||
* le fichier de preseed `libretic.ks.j2`
|
||||
|
||||
|
||||
* Se placer dans le dossier ansible de ce projet et exécuter la génération des fichiers preseed qui seront utiles plus tard, et qui se trouveront dans le dossier `generated` après exécution de la commande :
|
||||
```bash
|
||||
cd cubic-linuxmint/ansible
|
||||
ansible-playbook configure-preseed.yml
|
||||
```
|
||||
|
||||
* Lancer cubic et créer un nouveau dossier projet
|
||||
|
||||
![Dossier de projet Cubic](doc/cubic-folder.png)
|
||||
|
||||
* Paramétrage de la personnalisation de l'image ; choisir l'image linux mint téléchargée et personnalisé comme suit :
|
||||
|
||||
![Écran de personnalisation de l'image](doc/original_disk_customization.png)
|
||||
|
||||
* On arrive sur un shell qui permet de taper des commandes de personnalisation
|
||||
|
||||
![Shell](doc/shell.png)
|
||||
|
||||
* Dans ce shell, taper les commandes suivantes :
|
||||
|
||||
```bash
|
||||
apt install -y git python3-poetry
|
||||
cd /opt
|
||||
git clone https://git.libretic.fr/libretic/libreticmenu.git
|
||||
cd libreticmenu
|
||||
./libreticmenu.sh --cubic
|
||||
```
|
||||
|
||||
* Une fois exécutées les commandes ci-dessus, passer à l'écran qui suit, qui propose de modifier la liste des packages qui doivent être supprimés dans l'image. Ne rien changer.
|
||||
|
||||
* L'écran suivant propose de modifier les options de démarrage. Dans l'onglet preseed de cet écran, créer plusieurs fichiers et y copier/coller les contenus des mêmes fichiers générés par ansible :
|
||||
* `libretic-nvme.ks`
|
||||
* `libretic-sda.ks`
|
||||
* `libretic-vda.ks`
|
||||
|
||||
![L'onglet preseed une fois renseigné](doc/preseed.png)
|
||||
|
||||
* Dans l'onglet Boot, remplacer les contenus des fichiers grub.cfg et live.cfg par les contenus des fichiers générés par ansible :
|
||||
|
||||
![L'onglet boot une fois renseignée la zone grub.cfg](doc/boot-grub.png)
|
||||
|
||||
![L'onglet boot une fois renseignée la zone live.cfg](doc/boot-live.png)
|
||||
|
||||
* Les écrans suivant permettent de valider le taux de compression puis de générer l'image.
|
||||
|
||||
* Une fois générée, on obtient un écran de synthèse :
|
||||
|
||||
![Synthèse de l'image construite](doc/last.png)
|
||||
|
||||
* Le bouton "test" permet de tester l'image obtenue, mais il est préférable de tester avec virt-manager pour une meilleure simulation de ce qu'on obtiendra après sur un ordinateur.
|
||||
|
||||
* Une fois obtenu le résultat souhaité, il ne reste plus qu'à déposer l'image dans une clé usb (conseil : utiliser [Ventoy](https://www.ventoy.net)), puis amorcer un PC avec cette image.
