Utilisation¶

Build¶

# Build image principale
docker compose build sagwm-cc

# Build avec arguments personnalises
docker compose build \
  --build-arg CC_ADMIN_PASSWORD=MySecurePass \
  sagwm-cc

Demarrage¶

# Demarrer tous les services
docker compose up -d

# Demarrer seulement CC + SQL
docker compose up -d sagwm-cc sagwm-sql-server

# Avec profil SPM standalone
docker compose --profile spm-standalone up -d

Verification¶

# Status des containers
docker compose ps

# Logs en temps reel
docker compose logs -f sagwm-cc

# Status Supervisor dans le container
docker compose exec sagwm-cc supervisorctl status

Arret¶

# Arreter les services
docker compose down

# Arreter et supprimer les volumes
docker compose down -v

Gestion des services¶

Commandes Supervisor¶

# Entrer dans le container
docker compose exec sagwm-cc bash

# Status des services
supervisorctl status

# Redemarrer CCE
supervisorctl restart commandcentral

# Arreter SPM
supervisorctl stop platformmanager

# Voir les logs
supervisorctl tail -f commandcentral

Multi-plateforme¶

Oracle Linux 8¶

# docker/Dockerfile.supervisor.oraclelinux

FROM oraclelinux:8

RUN dnf install -y \
    supervisor \
    curl \
    unzip \
    && dnf clean all

# ... reste similaire

Avantages Oracle Linux :

Compatibilite RHEL
Support enterprise
Certifications Oracle

Windows (Experimental)¶

# docker/Dockerfile.windows.tofix

FROM mcr.microsoft.com/windows/servercore:ltsc2019

# En cours de developpement
# Necessite Windows containers

Volumes et persistance¶

volumes:
  # Scripts (lecture seule)
  - ./scripts:/scripts:ro

  # Installateur (lecture seule)
  - ./installer:/installer:ro

  # Donnees SQL Server (persistant)
  - sql-data:/var/opt/mssql

  # Logs (optionnel)
  - ./logs:/var/log/supervisor

Healthchecks¶

services:
  sagwm-cc:
    # ...
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8090/sag/cce/v1/health"]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 120s

Bonnes pratiques¶

Supervisor plutot que systemd - Plus adapte aux containers
Multi-stage builds - Reduire la taille des images
Volumes read-only - Securite pour scripts et installateur
Healthchecks - Detection automatique des problemes
Logs centralises - Via Supervisor vers stdout
Variables d'environnement - Configuration flexible
