 ## Aide
 
-Commande pour se connecter à un serveur :
+Exemple de commande :
 
 ```sh
-. .env
-docker exec --user www-data -it ${NEXTCLOUD_CONTAINER_NAME}-fpm ash
-```
+docker exec --user www-data -it nextcloud bash
 
-Pour mettre un site en maintenance :
-
-```sh
-. .env
-docker exec --user www-data -it ${NEXTCLOUD_CONTAINER_NAME}-fpm php occ maintenance:mode --on
+docker-compose exec --user www-data nextcloud php occ db:add-missing-primary-keys
 ```
 
 ## Configuration
 
-Il est possible de configurer certaines parties avec des variables d'environnement :
-- Soit les variables sont spécifique à l'image Docker 
-- soit avec des variables du type `NC_` + clé (exemple : NC_default_phone_region=FR)
+Il est possible de configurer certaines parties avec des variables d'environnement, mais ce n'est pas le cas de l'ensemble de la configuration.
 
-### Création d'un groupe
+Voici les modifications que j'effectue :
 
 ```
-export NC_GROUP=com-en-aubrac
-php occ group:add $NC_GROUP
+docker-compose exec --user www-data nextcloud-fpm ash
+vi config/config.php
+```
+Ajout de la configuration suivante :
+```
+  'default_language' => 'fr',
+  'default_locale' => 'fr_FR',
+  'default_phone_region' => 'FR',
+  'defaultapp' => 'files',
+  'preview_max_x' => 2048,
+  'preview_max_y' => 2048,
+  'jpeg_quality' => 60,
 ```
 
-### Création d'un utilisateur
-
+Ajout de imagemagick :
 ```
-# La variable OC_PASS est spécifique pour l'utilisation de --password-from-env
-export OC_PASS=unmotdepasse!
-
-export NC_USER=simon
-export NC_NAME=Simon
-export NC_MAIL=simon@example.org
-export NC_QUOTA="180 GB"
-
-php occ user:add --password-from-env --display-name=$NC_NAME --group="$NC_GROUP" $NC_USER
-php occ user:setting $NC_USER settings email $NC_MAIL
+docker-compose exec nextcloud-fpm apk add --no-cache imagemagick
 ```
 
-### Quota
-
-Pour bien comprendre les quotas dans Nextcloud : https://docs.nextcloud.com/server/latest/user_manual/en/files/quota.html
+ou
 
 ```
-export NC_USER=simon
-export NC_QUOTA="10 GB"
-php occ user:setting $NC_USER files quota "$NC_QUOTA"
-```
-
-### imagemagick
-
-> Le module php-imagick n’a aucun support SVG dans cette instance. Pour une meilleure compatibilité, il est recommandé de l’installer.
-
-Pour résoudre ce problème il faut ajouter le paquet `imagemagick`
-
-```
-. .env
-docker exec -it ${NEXTCLOUD_CONTAINER_NAME}-fpm apk add --no-cache imagemagick
-```
-
-## Application
-
-Suppression d'application :
-
-```
-php occ app:disable dashboard
-php occ app:disable photos
-php occ app:disable weather_status
-php occ app:disable user_status
+ssh <server>
+docker exec nextcloud-fpm apk add --no-cache imagemagick
 ```
