 # Installation de LoreMindMJ
 
-## Prerequis
+Ce document decrit la procedure d'installation de LoreMindMJ. Temps estime :
+5 a 10 minutes selon la qualite de la connexion reseau.
 
-- **Docker Desktop** ([Windows](https://www.docker.com/products/docker-desktop/) / [Mac](https://www.docker.com/products/docker-desktop/))
-  ou **Docker Engine + Compose v2** (Linux).
-- (Optionnel) **[Ollama](https://ollama.com/)** si tu veux un LLM local.
-  Sinon, une cle API [1min.ai](https://1min.ai) suffit.
+## 1. Prerequis
 
-## Installation (5 minutes)
-
-1. Telecharge `docker-compose.yml` et `.env.example` depuis la [derniere release](https://git.igmlcreation.fr/ietm64/LoreMindMJ/releases) dans un dossier a toi.
-
-2. Renomme `.env.example` en `.env` et ouvre-le dans un editeur texte. Trois variables sont **obligatoires** :
-   - `POSTGRES_PASSWORD` : mot de passe de la base (choisis-en un).
-   - `ADMIN_PASSWORD` : protege l'ecran Parametres de l'appli. Tu le taperas dans une popup du navigateur.
-   - `BRAIN_INTERNAL_SECRET` : secret interne partage entre les services. Genere une valeur aleatoire :
+- **Docker Desktop** ([Windows](https://www.docker.com/products/docker-desktop/) /
+  [Mac](https://www.docker.com/products/docker-desktop/)) ou
+  **Docker Engine + Compose v2** (Linux). Verification :
   ```
-     openssl rand -hex 32
+  docker --version
+  docker compose version
   ```
-     (Sous Windows sans openssl : utilise un generateur en ligne type "random hex string 64 chars".)
+  Compose v2 est requis : la commande est `docker compose`, non `docker-compose`.
 
-   Sans ces trois variables, `docker compose up` refusera de demarrer — c'est volontaire pour eviter un deploiement non-securise par defaut.
+- **Un fournisseur LLM**, au choix :
+  - **[Ollama](https://ollama.com/)** installe sur la machine hote (gratuit,
+    local, necessite environ 6 Go de RAM libre pour les modeles recommandes).
+  - **Une cle API [1min.ai](https://1min.ai)** (hebergement cloud, facturation
+    a l'usage, aucune installation supplementaire requise).
 
-3. Dans un terminal, place-toi dans le dossier et lance :
-   ```
-   docker compose up -d
-   ```
-   Le premier demarrage telecharge les images (~500 Mo) et initialise la base. Compte 1-2 minutes.
+- Environ **2 Go d'espace disque** pour les images Docker, auxquels s'ajoute
+  la taille des modeles Ollama si l'option locale est retenue.
 
-4. Ouvre http://localhost:8081 dans ton navigateur. Bon jeu !
+## 2. Recuperation des fichiers
 
-## Mise a jour
+Telecharger les deux fichiers suivants depuis la
+[derniere release](https://git.igmlcreation.fr/ietm64/LoreMindMJ/releases) et
+les placer dans un dossier dedie (par exemple `~/loremind/` ou
+`C:\Programs\loremind\`) :
+
+- `docker-compose.yml`
+- `.env.example`
+
+Le code source n'est pas necessaire : les images sont pre-construites et
+publiees sur le registry Gitea `git.igmlcreation.fr` (non Docker Hub). Le
+premier `docker compose pull` les telechargera automatiquement.
+
+## 3. Configuration du fichier `.env`
+
+Renommer `.env.example` en `.env` et l'ouvrir dans un editeur de texte. **Trois
+variables sont obligatoires** ; sans elles, `docker compose up` refusera de
+demarrer. Ce comportement est volontaire afin d'eviter tout deploiement
+non-securise par defaut.
+
+### `POSTGRES_PASSWORD`
+
+Mot de passe de la base de donnees PostgreSQL. Choisir une valeur robuste.
+Seuls les conteneurs utilisent cette valeur : il n'est pas necessaire de la
+memoriser au-dela du fichier `.env`.
+
+### `ADMIN_PASSWORD`
+
+Protege l'ecran **Parametres** de l'application via HTTP Basic. Cette valeur
+sera demandee par le navigateur lors de toute modification de la configuration
+(changement de modele LLM, saisie de cle API, etc.). Le nom d'utilisateur par
+defaut est `admin`, modifiable via la variable `ADMIN_USERNAME`.
+
+### `BRAIN_INTERNAL_SECRET`
+
+Secret partage entre le service Java (`core`) et le service Python (`brain`).
+Empeche toute requete externe d'atteindre directement le service Brain.
+Generer une valeur aleatoire de 64 caracteres hexadecimaux :
+
+```
+openssl rand -hex 32
+```
+
+Sous Windows sans `openssl`, utiliser PowerShell :
+
+```powershell
+-join ((48..57) + (97..102) | Get-Random -Count 64 | % {[char]$_})
+```
+
+### Variables optionnelles
+
+- `WEB_PORT` (defaut `8081`) : port d'ecoute de l'interface web.
+- `ADMIN_USERNAME` (defaut `admin`) : identifiant de la popup Parametres.
+- `LLM_PROVIDER` (defaut `ollama`) : choix du fournisseur LLM (voir
+  section 5).
+
+Les autres variables (`MINIO_USER`/`MINIO_PASSWORD`, `POSTGRES_DB`,
+`POSTGRES_USER`) disposent de valeurs par defaut adaptees a un deploiement
+personnel et peuvent etre conservees en l'etat.
+
+## 4. Lancement de la stack
+
+Depuis le dossier contenant `docker-compose.yml` et `.env` :
+
+```
+docker compose up -d
+```
+
+Le premier demarrage telecharge les images (environ 1 a 2 Go au total) et
+initialise la base. Compter 2 a 5 minutes selon la qualite de la connexion.
+La progression peut etre suivie via :
+
+```
+docker compose logs -f
+```
+
+(`Ctrl+C` pour quitter l'affichage ; les services continuent de fonctionner
+en arriere-plan.)
+
+Une fois les services en etat `healthy`, ouvrir **http://localhost:8081**
+dans un navigateur.
+
+### Verification du fonctionnement
+
+```
+docker compose ps
+```
+
+Cinq conteneurs doivent apparaitre en etat `Up` ou `healthy` :
+`loremind-postgres`, `loremind-minio`, `loremind-core`, `loremind-brain`,
+`loremind-web`. Le conteneur `loremind-minio-init` s'arrete automatiquement
+apres creation du bucket d'images : ce comportement est normal.
+
+## 5. Configuration du fournisseur LLM
+
+### Ollama (local, gratuit)
+
+Installer Ollama sur la machine hote (pas dans Docker), puis telecharger un
+modele :
+
+```
+ollama pull gemma4:26b
+```
+
+Dans `.env` :
+
+```
+LLM_PROVIDER=ollama
+LLM_MODEL=gemma4:26b
+OLLAMA_BASE_URL=http://host.docker.internal:11434
+```
+
+L'adresse `host.docker.internal` permet au conteneur `brain` d'atteindre
+Ollama sur la machine hote. Cette resolution est native sous Docker Desktop
+(Mac / Windows). Sous Linux, le fichier `docker-compose.yml` declare un
+`extra_hosts` equivalent.
+
+### 1min.ai (cloud, paye)
+
+Dans `.env` :
+
+```
+LLM_PROVIDER=onemin
+ONEMIN_API_KEY=sk-...
+ONEMIN_MODEL=gpt-4o-mini
+```
+
+### Modification a chaud
+
+Le fournisseur, le modele et la cle API peuvent etre modifies a chaud depuis
+l'ecran **Parametres** de l'application. Les modifications sont persistees
+dans un volume Docker et survivent aux redemarrages. Les variables d'env du
+fichier `.env` sont uniquement utilisees comme valeurs initiales au premier
+demarrage.
+
+## 6. Mise a jour
 
 ```
 docker compose pull
 docker compose up -d
 ```
 
-Les donnees (base Postgres, images MinIO, settings Brain) sont dans des volumes Docker et survivent aux mises a jour.
+Les donnees (base PostgreSQL, images MinIO, configuration Brain) sont
+stockees dans des volumes Docker et survivent aux mises a jour.
 
-## LLM : Ollama ou 1min.ai ?
+## 7. Sauvegarde
 
-**Ollama (local, gratuit)** — Edite `.env` :
-```
-LLM_PROVIDER=ollama
-LLM_MODEL=gemma4:26b
-```
-Telecharge le modele au prealable : `ollama pull gemma4:26b`.
+Les donnees sont reparties dans trois volumes Docker :
 
-**1min.ai (cloud, paye)** — Edite `.env` :
-```
-LLM_PROVIDER=onemin
-ONEMIN_API_KEY=sk-...
-ONEMIN_MODEL=open-mistral-nemo
-```
+- `loremindmj_postgres-data` — ensemble des donnees applicatives (lores,
+  campagnes, pages, templates, branches narratives, etc.).
+- `loremindmj_minio-data` — images uploadees.
+- `loremindmj_brain-data` — parametres IA (fournisseur courant, cle API
+  1min.ai).
 
-Tu peux aussi changer tout ca a chaud depuis l'ecran Parametres de l'appli.
+### Export SQL de la base
 
-## Problemes frequents
-
-- **Port 8081 deja pris** : change `WEB_PORT=8082` (ou autre) dans `.env`.
-- **Ollama injoignable** : verifie qu'Ollama tourne (`ollama serve`) et que le modele est bien telecharge.
-- **"set ADMIN_PASSWORD in .env" / "set BRAIN_INTERNAL_SECRET in .env"** au lancement : tu as oublie une des variables obligatoires de l'etape 2.
-- **Popup "Ce site vous demande de vous connecter" sur l'ecran Parametres** : c'est normal. Utilise `admin` (ou ce que tu as mis dans `ADMIN_USERNAME`) et ton `ADMIN_PASSWORD`.
-- **Tout casser et repartir de zero** : `docker compose down -v` supprime les volumes (attention, perte de donnees).
-
-## Sauvegarde
-
-Les donnees sont dans les volumes Docker : `loremindmj_postgres-data`, `loremindmj_minio-data`, `loremindmj_brain-data`.
-
-Sauvegarde rapide de la base :
 ```
 docker compose exec postgres pg_dump -U loremind loremind > backup.sql
 ```
+
+### Sauvegarde complete des volumes
+
+Arreter la stack au prealable afin de garantir la coherence des donnees :
+
+```
+docker compose stop
+docker run --rm -v loremindmj_postgres-data:/data -v $(pwd):/backup alpine tar czf /backup/postgres-data.tar.gz -C /data .
+docker run --rm -v loremindmj_minio-data:/data -v $(pwd):/backup alpine tar czf /backup/minio-data.tar.gz -C /data .
+docker compose start
+```
+
+Sous Windows PowerShell, remplacer `$(pwd)` par `${PWD}`.
+
+## 8. Resolution des problemes
+
+### Port 8081 deja utilise
+
+Modifier `WEB_PORT=8082` (ou toute autre valeur libre) dans `.env`, puis
+relancer :
+
+```
+docker compose up -d
+```
+
+### Erreur "set POSTGRES_PASSWORD in .env" (ou variable equivalente) au lancement
+
+Une des trois variables obligatoires de l'etape 3 est manquante. Verifier le
+contenu du fichier `.env`.
+
+### Popup "Ce site vous demande de vous connecter" sur l'ecran Parametres
+
+Comportement attendu : il s'agit de l'authentification HTTP Basic. Utiliser
+la valeur de `ADMIN_USERNAME` (par defaut `admin`) et celle de
+`ADMIN_PASSWORD`.
+
+### Erreurs `password authentication failed` en boucle dans les logs Postgres
+
+Si la variable `POSTGRES_PASSWORD` a ete modifiee apres un premier lancement,
+le volume Postgres conserve l'ancien mot de passe (initialise une seule fois).
+Deux options :
+
+- **Redemarrer avec un volume vierge** (entraine la perte des donnees) :
+  ```
+  docker compose down -v
+  docker compose up -d
+  ```
+- **Modifier le mot de passe en base** sans toucher au volume :
+  ```
+  docker compose exec postgres psql -U postgres
+  ```
+  Puis dans le prompt `psql` :
+  ```sql
+  ALTER USER loremind WITH PASSWORD 'valeur_exacte_du_env';
+  \q
+  ```
+  Redemarrer ensuite le Core : `docker compose restart core`.
+
+### Erreur "502 Bad Gateway" ou message d'erreur IA dans l'interface
+
+Le service Brain ne parvient pas a contacter le fournisseur LLM. Verifier :
+
+- **Ollama** : `ollama serve` est-il actif ? Le modele est-il telecharge
+  (`ollama list`) ? La valeur de `LLM_MODEL` correspond-elle exactement au
+  nom d'un modele liste ?
+- **1min.ai** : la cle API est-elle valide ? Le modele existe-t-il ?
+- Consulter les logs du Brain :
+  ```
+  docker compose logs brain
+  ```
+
+### Un service ne demarre pas ou reste en etat `unhealthy`
+
+Consulter les logs du service concerne :
+
+```
+docker compose logs <service>
+```
+
+Services disponibles : `postgres`, `minio`, `core`, `brain`, `web`.
+
+### Redemarrage d'un service apres modification du `.env`
+
+```
+docker compose up -d <service>
+```
+
+Redemarrage complet : `docker compose restart`.
+
+### Remise a zero complete (PERTE DES DONNEES)
+
+```
+docker compose down -v
+```
+
+L'option `-v` supprime les volumes. L'ensemble des lores, campagnes, images
+et parametres est perdu de maniere definitive.
+
+### "No such image" ou "pull access denied" au premier lancement
+
+Le registry Gitea peut necessiter une authentification selon la visibilite
+configuree pour les images. Contacter l'editeur du projet.
+
+## 9. Exposition reseau des services
+
+- **Interface web** : http://localhost:8081 (port configurable via
+  `WEB_PORT`).
+- **PostgreSQL** : accessible uniquement via le reseau Docker interne, non
+  expose vers l'hote.
+- **MinIO** : accessible uniquement via le reseau Docker interne. Les images
+  transitent par le reverse-proxy Java sur `/api/images/{id}/content`. Le
+  binding `127.0.0.1:9000/9001` defini dans `docker-compose.override.yml`
+  n'est actif qu'en developpement.
+- **Brain Python** : accessible uniquement via le reseau Docker interne.
+  Toute requete doit porter l'en-tete `X-Internal-Secret`, injectee
+  automatiquement par le Core Java et jamais exposee au navigateur.
+
+## 10. Desinstallation
+
+```
+docker compose down -v
+docker image rm git.igmlcreation.fr/ietm64/core git.igmlcreation.fr/ietm64/brain git.igmlcreation.fr/ietm64/web
+```
+
+Supprimer ensuite le dossier contenant `docker-compose.yml` et `.env`.
