|
|
|
|
---
|
|
|
|
## 📋 Prérequis
|
|
|
|
### 1. Docker Installé
|
|
```bash
|
|
docker --version
|
|
# Docker version 24.0.0 ou supérieur
|
|
```
|
|
|
|
### 2. Docker Registry Access
|
|
- **Docker Hub**: Créer un compte sur https://hub.docker.com
|
|
- **Ou** GitHub Container Registry (GHCR)
|
|
- **Ou** Registry privé
|
|
|
|
### 3. Login au Registry
|
|
```bash
|
|
# Docker Hub
|
|
docker login
|
|
|
|
# GitHub Container Registry
|
|
echo $GITHUB_TOKEN | docker login ghcr.io -u USERNAME --password-stdin
|
|
|
|
# Registry privé
|
|
docker login registry.example.com
|
|
```
|
|
|
|
---
|
|
|
|
## 🚀 Méthode 1: Script Automatique (Recommandé)
|
|
|
|
### Build Staging
|
|
|
|
```bash
|
|
# Build seulement (pas de push)
|
|
./docker/build-images.sh staging
|
|
|
|
# Build ET push vers Docker Hub
|
|
./docker/build-images.sh staging --push
|
|
```
|
|
|
|
### Build Production
|
|
|
|
```bash
|
|
# Build seulement
|
|
./docker/build-images.sh production
|
|
|
|
# Build ET push
|
|
./docker/build-images.sh production --push
|
|
```
|
|
|
|
### Configuration du Registry
|
|
|
|
Par défaut, le script utilise `docker.io/xpeditis` comme registry.
|
|
|
|
Pour changer:
|
|
```bash
|
|
export DOCKER_REGISTRY=ghcr.io
|
|
export DOCKER_REPO=your-org
|
|
./docker/build-images.sh staging --push
|
|
```
|
|

|
|
docker push xpeditis/frontend:latest
|
|
```
|
|
|

|
|
|
|
## 🧪 Tester les Images Localement
|
|
|
|
### 1. Créer un network Docker
|
|
|
|
```bash
|
|
docker network create xpeditis-test
|
|
```
|
|
|
|
### 2. Lancer PostgreSQL
|
|
|
|
```bash
|
|
docker run -d \
|
|
--name postgres-test \
|
|
--network xpeditis-test \
|
|
-e POSTGRES_DB=xpeditis_test \
|
|
-e POSTGRES_USER=xpeditis \
|
|
-e POSTGRES_PASSWORD=test123 \
|
|
-p 5432:5432 \
|
|
postgres:15-alpine
|
|
```
|
|
|
|
### 3. Lancer Redis
|
|
|
|
```bash
|
|
docker run -d \
|
|
--name redis-test \
|
|
--network xpeditis-test \
|
|
-p 6379:6379 \
|
|
redis:7-alpine \
|
|
redis-server --requirepass test123
|
|
```
|
|
|
|
### 4. Lancer Backend
|
|
|
|
```bash
|
|
docker run -d \
|
|
--name backend-test \
|
|
--network xpeditis-test \
|
|
-e NODE_ENV=development \
|
|
-e PORT=4000 \
|
|
-e DATABASE_HOST=postgres-test \
|
|
-e DATABASE_PORT=5432 \
|
|
-e DATABASE_NAME=xpeditis_test \
|
|
-e DATABASE_USER=xpeditis \
|
|
-e DATABASE_PASSWORD=test123 \
|
|
-e REDIS_HOST=redis-test \
|
|
-e REDIS_PORT=6379 \
|
|
-e REDIS_PASSWORD=test123 \
|
|
-e JWT_SECRET=test-secret-key-256-bits-minimum-length-required \
|
|
-e CORS_ORIGIN=http://localhost:3000 \
|
|
-p 4000:4000 \
|
|
xpeditis/backend:staging-latest
|
|
```
|
|
|
|
### 5. Lancer Frontend
|
|
|
|
```bash
|
|
docker run -d \
|
|
--name frontend-test \
|
|
--network xpeditis-test \
|
|
-e NODE_ENV=development \
|
|
-e NEXT_PUBLIC_API_URL=http://localhost:4000 \
|
|
-e NEXT_PUBLIC_APP_URL=http://localhost:3000 \
|
|
-e API_URL=http://backend-test:4000 \
|
|
-p 3000:3000 \
|
|
xpeditis/frontend:staging-latest
|
|
```
|
|
|
|
### 6. Vérifier
|
|
|
|
```bash
|
|
# Backend health check
|
|
curl http://localhost:4000/health
|
|
|
|
# Frontend
|
|
curl http://localhost:3000/api/health
|
|
|
|
# Ouvrir dans navigateur
|
|
open http://localhost:3000
|
|
```
|
|
|
|
### 7. Voir les logs
|
|
|
|
```bash
|
|
docker logs -f backend-test
|
|
docker logs -f frontend-test
|
|
```
|
|
|
|
### 8. Nettoyer
|
|
|
|
```bash
|
|
docker stop backend-test frontend-test postgres-test redis-test
|
|
docker rm backend-test frontend-test postgres-test redis-test
|
|
docker network rm xpeditis-test
|
|
```

## 📊 Optimisation des Images
|
|
|
|
### Tailles d'Images Typiques
|
|
|
|
- **Backend**: ~150-200 MB (après compression)
|
|
- **Frontend**: ~120-150 MB (après compression)
|
|
- **Total**: ~300 MB (pour les 2 images)
|
|
|
|
### Multi-Stage Build
|
|
|
|
Les Dockerfiles utilisent des builds multi-stage:
|
|
|
|
1. **Stage Dependencies**: Installation des dépendances
|
|
2. **Stage Builder**: Compilation TypeScript/Next.js
|
|
3. **Stage Production**: Image finale (seulement le nécessaire)
|
|
|
|
Avantages:
|
|
- ✅ Images légères (pas de dev dependencies)
|
|
- ✅ Build rapide (cache des layers)
|
|
- ✅ Sécurisé (pas de code source dans prod)
|
|
|
|
### Build Cache
|
|
|
|
Pour accélérer les builds:
|
|
|
|
```bash
|
|
# Build avec cache
|
|
docker build --cache-from xpeditis/backend:staging-latest -t xpeditis/backend:staging-latest .
|
|
|
|
# Ou avec BuildKit (plus rapide)
|
|
DOCKER_BUILDKIT=1 docker build -t xpeditis/backend:staging-latest .
|
|
```
|
|
|
|
### Scan de Vulnérabilités
|
|
|
|
```bash
|
|
# Scan avec Docker Scout (gratuit)
|
|
docker scout cves xpeditis/backend:staging-latest
|
|
|
|
# Scan avec Trivy
|
|
trivy image xpeditis/backend:staging-latest
|
|
```
|
|
|

## 🔄 CI/CD Integration
|
|
|
|
### GitHub Actions Example
|
|
|
|
Voir `.github/workflows/docker-build.yml` (à créer):
|
|
|
|
```yaml
|
|
name: Build and Push Docker Images
|
|
|
|
on:
|
|
push:
|
|
branches:
|
|
- main
|
|
- develop
|
|
|
|
jobs:
|
|
build:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- uses: actions/checkout@v3
|
|
|
|
- name: Login to Docker Hub
|
|
uses: docker/login-action@v2
|
|
with:
|
|
username: ${{ secrets.DOCKER_USERNAME }}
|
|
password: ${{ secrets.DOCKER_PASSWORD }}
|
|
|
|
- name: Build and Push
|
|
run: |
|
|
if [[ "${{ github.ref }}" == "refs/heads/main" ]]; then
|
|
./docker/build-images.sh production --push
|
|

## 🐛 Dépannage
|
|
|
|
### Problème 1: Build échoue avec erreur "npm ci"
|
|
|
|
**Symptôme**: `npm ci` failed with exit code 1
|
|
|
|
**Solution**:
|
|
```bash
|
|
# Nettoyer le cache Docker
|
|
docker builder prune -a
|
|
|
|
# Rebuild sans cache
|
|
docker build --no-cache -t xpeditis/backend:staging-latest apps/backend/
|
|
```
|
|
|
|
### Problème 2: Image trop grosse (>500 MB)
|
|
|
|
**Symptôme**: Image très volumineuse
|
|
|
|
**Solution**:
|
|
- Vérifier que `.dockerignore` est présent
|
|
- Vérifier que `node_modules` n'est pas copié
|
|
- Utiliser `npm ci` au lieu de `npm install`
|
|
|
|
```bash
|
|
# Analyser les layers
|
|
docker history xpeditis/backend:staging-latest
|
|
```
|
|
|
|
### Problème 3: Next.js standalone build échoue
|
|
|
|
**Symptôme**: `Error: Cannot find module './standalone/server.js'`
|
|
|
|
**Solution**:
|
|
- Vérifier que `next.config.js` a `output: 'standalone'`
|
|
- Rebuild frontend:
|
|
```bash
|
|
cd apps/frontend
|
|
npm run build
|
|
# Vérifier que .next/standalone existe
|
|
ls -la .next/standalone
|
|
```
|
|
|
|
### Problème 4: CORS errors en production
|
|
|
|
**Symptôme**: Frontend ne peut pas appeler le backend
|
|
|
|
**Solution**:
|
|
- Vérifier `CORS_ORIGIN` dans backend
|
|
- Vérifier `NEXT_PUBLIC_API_URL` dans frontend
|
|
- Tester avec curl:
|
|
```bash
|
|
curl -H "Origin: https://staging.xpeditis.com" \
|
|
-H "Access-Control-Request-Method: GET" \
|
|
-X OPTIONS \
|
|
https://api-staging.xpeditis.com/health
|
|
```
|
|
|
|
### Problème 5: Health check fails
|
|
|
|
**Symptôme**: Container restart en boucle
|
|
|
|
**Solution**:
|
|
```bash
|
|
# Voir les logs
|
|
docker logs backend-test
|
|
|
|
# Tester health check manuellement
|
|
docker exec backend-test curl -f http://localhost:4000/health
|
|
|
|
# Si curl manque, installer:
|
|
docker exec backend-test apk add curl
|
|
```

|
|
|
|
## 📈 Métriques de Build
|
|
|
|
Après chaque build, vérifier:
|
|
|
|
```bash
|
|
# Taille des images
|
|
docker images | grep xpeditis
|
|
|
|
# Layers count
|
|
docker history xpeditis/backend:staging-latest | wc -l
|
|
|
|
# Scan vulnérabilités
|
|
docker scout cves xpeditis/backend:staging-latest
|
|
```
|
|
|
|
**Objectifs**:
|
|
- ✅ Backend < 200 MB
|
|
- ✅ Frontend < 150 MB
|
|
- ✅ Build time < 5 min
|
|
- ✅ Zéro vulnérabilité critique
