This Ibexa DXP v3.x+ bundle provides a simple way to switch the whole site or selected SiteAccess to maintenance mode.

In this mode the site (or particular SiteAccess) will not be available for the end-users. Selected template is displayed instead.

• Install the bundle:

composer require kmadejski/ezplatform-maintenance-mode

• If you do not use Symfony Flex, you have to enable the bundle manually in your config/bundles.php file:

    ...
    EzSystems\EzPlatformMaintenanceModeBundle\EzSystemsEzPlatformMaintenanceModeBundle::class => ['all' => true]

• Clear application cache:

php bin/console cache:clear --env=prod

Bundles configuratiton is SiteAccess-aware, therefore all options are configurable in ezplatform.yml under default SiteAccess configuration key (if you want to switch the whole site into maintenance mode) or under selected SiteAccess:

ezplatform:
    system:
        default:
            maintenance_mode:
                enabled: true

By default 503 HTTP response code is returned and a default template @EzSystemsEzPlatformMaintenanceMode/maintenance.html.twig is rendered. No IP addresses are allowed to visit the page. To modify this behaviour you can add an additional configuration as following example presents:

ezplatformgs:
    system:
        default:
            maintenance_mode:
                enabled: true
                allowed_ips: ['::1', '10.0.0.1', '192.168.0.0/16']
                response_code: 404
                template: '@Acme/custom_maintenance.html.twig'
