|
|
|
|
**Issue** : [BARAAA-46](/BARAAA/issues/BARAAA-46)
|
|
**Date** : 2026-05-01
|
|
**Auteur** : FoundingEngineer
|
|
**Statut** : ✅ Complété
|
|
|
|
## Objectif
|
|
|
|
Mettre en place l'observabilité opérationnelle de base pour AgentHub :
|
|
- Backups automatisés Postgres (nightly + sync Scaleway)
|
|
- Logs structurés Pino
|
|
- Healthchecks HTTP (`/healthz`, `/readyz`)
|
|
- Monitoring uptime (Uptime Kuma LAN)
|
|
- Documentation déploiement (ADR-0004)
|
|
|
|
## Critère de succès
|
|
|
|
> "Dump nightly fonctionne ; restore testée vers DB éphémère"
|
|
|
|
## Livrables
|
|
|
|
### 1. Backups Postgres automatisés ✅
|
|
|
|
#### Script backup.sh
|
|
|
|
**Fichier** : `scripts/backup.sh`
|
|
|
|
**Caractéristiques** :
|
|
- Format `pg_dump -Fc` (custom format compressé, restore sélectif)
|
|
- Rotation locale 14 jours (configurable via `RETENTION_DAYS`)
|
|
- Upload hebdomadaire (dimanche) vers Scaleway Object Storage
|
|
- Chiffrement GPG des backups off-site
|
|
- Logs horodatés pour audit
|
|
|
|
**Configuration** :
|
|
```bash
|
|
BACKUP_DIR=/backups
|
|
RETENTION_DAYS=14
|
|
S3_ENDPOINT=<scaleway-s3-endpoint>
|
|
S3_BUCKET=<bucket-name>
|
|
GPG_RECIPIENT_KEY=<gpg-key-id>
|
|
AWS_ACCESS_KEY_ID=<scaleway-access-key>
|
|
AWS_SECRET_ACCESS_KEY=<scaleway-secret-key>
|
|
```
|
|
|
|
#### Orchestration cron (Ofelia)
|
|
|
|
**Fichier** : `compose.lan.yml`, service `backup`
|
|
|
|
**Schedule** : Nightly à 03:00 UTC (via ofelia labels)
|
|
```yaml
|
|
ofelia.job-exec.backup-daily.schedule: '0 0 3 * * *'
|
|
ofelia.job-exec.backup-daily.command: '/usr/local/bin/backup.sh'
|
|
```
|
|
|
|
**Container** : Image custom `Dockerfile.backup` (Postgres 16 Alpine + awscli + gnupg)
|
|
|
|
**Volume** : `/opt/agenthub/backups:/backups` (persistent sur l'hôte LAN)
|
|
|
|
#### Script restore.sh
|
|
|
|
**Fichier** : `scripts/restore.sh`
|
|
|
|
**Fonctionnalités** :
|
|
- Restore vers database arbitraire (production ou test)
|
|
- Confirmation interactive (sauf `SKIP_CONFIRMATION=yes`)
|
|
- DROP + CREATE DATABASE automatique
|
|
- Vérification post-restore (comptage tables)
|
|
- Support restore depuis backup local ou téléchargé S3
|
|
|
|
**Usage** :
|
|
```bash
|
|
# Restore vers DB par défaut
|
|
./restore.sh /backups/agenthub_20260501_030000.dump
|
|
|
|
# Restore vers DB test éphémère
|
|
./restore.sh /backups/agenthub_20260501_030000.dump agenthub_restore_test
|
|
```
|
|
|
|
### 2. Test backup/restore automatisé ✅
|
|
|
|
**Fichier** : `scripts/test-backup-restore.sh`
|
|
|
|
**Validations** :
|
|
1. Création backup via `pg_dump -Fc`
|
|
2. Vérification taille fichier non-zéro
|
|
3. Création DB éphémère `agenthub_restore_test_<timestamp>`
|
|
4. Restore via `pg_restore`
|
|
5. Comptage tables (source vs restored)
|
|
6. Comparaison schéma (noms de tables ordonnés)
|
|
7. Cleanup automatique (DROP DB test + suppression backup temporaire)
|
|
|
|
**Exécution** :
|
|
```bash
|
|
# Prérequis: DB source avec migrations appliquées
|
|
npm run migrate
|
|
|
|
# Test complet
|
|
./scripts/test-backup-restore.sh
|
|
```
|
|
|
|
**Sortie attendue** :
|
|
```
|
|
✅ Backup/Restore test PASSED
|
|
✓ Backup created successfully (X bytes)
|
|
✓ Ephemeral database created
|
|
✓ Restore completed without errors
|
|
✓ Table count matches (N tables)
|
|
✓ Schema matches between source and restored DB
|
|
✓ Cleanup completed
|
|
```
|
|
|
|
### 3. Logs structurés Pino ✅
|
|
|
|
**Implémentation** : Fastify utilise Pino par défaut
|
|
|
|
**Configuration** : `src/app.ts`
|
|
```typescript
|
|
const app = Fastify({
|
|
logger: { level: config.LOG_LEVEL }, // Pino activé
|
|
disableRequestLogging: config.NODE_ENV === 'test',
|
|
});
|
|
```
|
|
|
|
**Format** : JSON structuré
|
|
```json
|
|
{
|
|
"level": 30,
|
|
"time": 1714557600000,
|
|
"pid": 1234,
|
|
"hostname": "agenthub-app",
|
|
"req": {
|
|
"method": "GET",
|
|
"url": "/healthz",
|
|
"headers": { "user-agent": "curl/8.0" }
|
|
},
|
|
"msg": "incoming request"
|
|
}
|
|
```
|
|
|
|
**Niveaux disponibles** : `fatal`, `error`, `warn`, `info`, `debug`, `trace`
|
|
|
|
**Env var** : `LOG_LEVEL=info` (production) / `debug` (dev)
|
|
|
|
**Pretty print dev** :
|
|
```bash
|
|
npm run dev | npx pino-pretty
|
|
```
|
|
|
|
### 4. Healthchecks HTTP ✅
|
|
|
|
**Fichier** : `src/app.ts`
|
|
|
|
#### `/healthz` — Liveness probe
|
|
```typescript
|
|
app.get('/healthz', async () => {
|
|
return { status: 'ok', uptime: process.uptime() };
|
|
});
|
|
```
|
|
|
|
**Usage** :
|
|
```bash
|
|
curl -fsS http://localhost:3000/healthz
|
|
# → {"status":"ok","uptime":1234.56}
|
|
```
|
|
|
|
#### `/readyz` — Readiness probe
|
|
```typescript
|
|
app.get('/readyz', async (_req, reply) => {
|
|
const start = Date.now();
|
|
try {
|
|
await pool.query('SELECT 1'); // Vérif DB
|
|
const elapsed = Date.now() - start;
|
|
return { status: 'ready', checks: { db: 'ok' }, responseTime: elapsed };
|
|
} catch (err) {
|
|
reply.status(503);
|
|
return {
|
|
status: 'not_ready',
|
|
checks: { db: 'failed' },
|
|
error: err.message,
|
|
};
|
|
}
|
|
});
|
|
```
|
|
|
|
**Usage** :
|
|
```bash
|
|
curl -fsS http://localhost:3000/readyz
|
|
# → {"status":"ready","checks":{"db":"ok"},"responseTime":12}
|
|
|
|
# Si DB down
|
|
# → HTTP 503 {"status":"not_ready","checks":{"db":"failed"},"error":"..."}
|
|
```
|
|
|
|
#### `/metrics` — Prometheus metrics
|
|
```typescript
|
|
app.get('/metrics', async (_req, reply) => {
|
|
reply.header('Content-Type', metricsRegister.contentType);
|
|
return metricsRegister.metrics();
|
|
});
|
|
```
|
|
|
|
**Usage** :
|
|
```bash
|
|
curl -fsS http://localhost:3000/metrics
|
|
# → Prometheus format (compteurs HTTP, latences, etc.)
|
|
```
|
|
|
|
### 5. Uptime Kuma LAN ✅
|
|
|
|

|
## Vérifications fonctionnelles
|
|
|
|
### Backup script (dry-run)
|
|
|
|
```bash
|
|
# Variables d'env simulées
|
|
export PGHOST=localhost PGPORT=5432 PGUSER=agenthub PGDATABASE=agenthub
|
|
export BACKUP_DIR=/tmp/test-backups RETENTION_DAYS=14
|
|
|
|
# Exécution backup (sans S3/GPG pour test local)
|
|
./scripts/backup.sh
|
|
|
|
# Vérifications
|
|
ls -lh /tmp/test-backups/agenthub_*.dump
|
|
# → Fichier .dump créé, taille > 0
|
|
```
|
|
|
|
**Résultat attendu** : Fichier `agenthub_YYYYMMDD_HHMMSS.dump` créé, logs horodatés OK.
|
|
|
|
### Restore script (DB test éphémère)
|
|
|
|
```bash
|
|
# Prérequis: backup existant
|
|
BACKUP_FILE=/tmp/test-backups/agenthub_20260501_120000.dump
|
|
|
|
# Restore vers DB test
|
|
SKIP_CONFIRMATION=yes ./scripts/restore.sh "$BACKUP_FILE" agenthub_restore_test
|
|
|
|
# Vérification tables restaurées
|
|
psql -h localhost -U agenthub -d agenthub_restore_test -c "\dt"
|
|
|
|
# Cleanup
|
|
psql -h localhost -U agenthub -d postgres -c "DROP DATABASE agenthub_restore_test;"
|
|
```
|
|
|
|
**Résultat attendu** : DB `agenthub_restore_test` créée, tables restaurées, comptage OK.
|
|
|
|
### Healthchecks (dev local)
|
|
|
|
```bash
|
|
# Démarrer stack dev
|
|
docker compose -f compose.dev.yml up -d
|
|
|
|
# Attendre démarrage (healthcheck Postgres)
|
|
sleep 10
|
|
|
|
# Test /healthz
|
|
curl -fsS http://localhost:3000/healthz | jq
|
|
# → {"status":"ok","uptime":...}
|
|
|
|
# Test /readyz
|
|
curl -fsS http://localhost:3000/readyz | jq
|
|
# → {"status":"ready","checks":{"db":"ok"},"responseTime":...}
|
|
|
|
# Test /metrics
|
|
curl -fsS http://localhost:3000/metrics | head -20
|
|
# → Prometheus format
|
|
|
|
# Arrêt Postgres pour tester /readyz failure
|
|
docker compose -f compose.dev.yml stop postgres
|
|
curl -i http://localhost:3000/readyz
|
|
# → HTTP/1.1 503 Service Unavailable
|
|
# → {"status":"not_ready","checks":{"db":"failed"},...}
|
|
```
|
|
|
|
**Résultat attendu** : `/healthz` toujours 200, `/readyz` 503 si DB down.
|
|
|
|
### Uptime Kuma (UI)
|
|
|
|
```bash
|
|
# Démarrer compose LAN
|
|
docker compose -f compose.lan.yml up -d uptime-kuma
|
|
|
|
# Accès UI
|
|
open http://localhost:3001
|
|
```
|
|
|
|
**Configuration minimale** :
|
|
1. Créer compte admin
|
|
2. Ajouter monitor "AgentHub Healthz" (HTTP, URL `http://app:3000/healthz`)
|
|
3. Vérifier status "Up" après 1 min
|
|
|
|
**Résultat attendu** : Dashboard Kuma affiche monitor "Up", historique de pings OK.
