USAGE
    $scriptname CMDs...

COMMANDES
    build [SERVICE]
        Construire les images
    push
        Pousser les images vers le serveur
    start, run [SERVICE]
        Démarrer le(s) service(s)
    stop [SERVICE]
        Arrêter le(s) service(s)
    up

        interactive.
    logs [SERVICE]
        Afficher les logs
    down
        Arrêter les services et supprimer l'environnement
    brd
        Construire les images (comme avec build), démarrer les services et
        suivre les logs de façon interactive (comme avec up). Dès que l'on
        arrête l'affichage des logs avec Ctrl+C, arrêter les services et
        supprimer l'environnement (comme avec down)
    bs
        Construire les images (comme avec build) puis démarrer les services
        (comme avec start)
    ip [SERVICE]
        Afficher l'adresse IP interne du service
    exec SERVICE COMMAND
        Lancer la commande dans le container spécifié
    systemd-unit
        Générer une unité systemd qui démarre les services. A priori, ce n'est
        nécessaire que si aucune politique de redémarrage n'a été définie.
    ps
        Afficher les containers en cours d'exécution
    ls
        Lister les images actuellement présentes
    rm
        Supprimer une image
    prune
        Supprimer les containers et les images inutilisées

OPTIONS générales
    (ces options sont communes à toutes les commandes)
    -d, --chdir PROJDIR
    -p, --profile PROFILE
    -P, --prod
    -T, --test
    -n, --fake
    -j, --no-cache
    -h, --host HOST

OPTIONS build
    (ces options ne sont valides que pour les commandes build, brd, bs)
    -g, --ug, --no-update-apps
        ne pas mettre à jour les dépôts dépendants. ces dépôts sont définis dans
        le fichier update-apps.conf qui a le format suivant:
            DEFAULT_BRANCH=
            APPS=()             # liste d'applications à mettre à jour
            app_URL=            # url du dépôt
            app_DEST=           # répertoire dans lequel faire le checkout
            app_PROFILE_ORIGIN= # origine spécifique à un profil
            app_PROFILE_BRANCH= # branche spécifique à un profil
            app_ORIGIN=         # ou... origine par défaut de la branche
            app_BRANCH=         # ou... branche par défaut
            app_TYPE=           # type de projet (composer par défaut)
            app_AFTER_UPDATE=() # liste de commandes à lancer après le checkout
    -u, --uu, --update-apps-only
        Ne faire que la mise à jour depuis les dépôts dépendants.
    --uo, --update-apps-origin ORIGIN
        Spécifier l'origine par défaut pour update-apps
    --ub, --update-apps-branch BRANCH
        Spécifier la branche par défaut pour update-apps

VARIABLES de update-apps.conf
    ORIGIN
        vaut 'origin' par défaut
    BRANCH
        vaut 'develop' par défaut
    TYPE
        vaut 'composer' par défaut si le fichier composer.json existe à la
        racine du projet. sinon vaut 'inconnu' par défaut
    AFTER_UPDATE
        Cette variable est une liste de commandes à lancer après la maj du dépôt
        - si le chemin est absolu ou relatif, lancer la commande telle quelle
        - s'il n'y a pas de chemin, alors ce doit être le nom d'une fonction
          existante auquel on enlève le préfixe update_apps_func_
FONCTIONS de update-apps.conf
    sqlmig [DESTDIR [SRCDIR]]

        SRCDIR/config/sqlmig vers DESTDIR/config/mariadb/sqlmig"
