erfans/maintenance-bundle

A Symfony bundle to allow maintenance mode for website.

A bundle to add maintenance mode to Symfony projects.

Installation

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:, _(*1)

$ composer require erfans/maintenance-bundle "~2.1"

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation., _(*2)

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the app/AppKernel.php file of your project:, _(*3)

<?php
// app/AppKernel.php

// ...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...

            new Erfans\MaintenanceBundle\ErfansMaintenanceBundle(),
        );

        // ...
    }

    // ...
}

Step 3: Add Routing

Add maintenance default controller route to app/config/routing.yml, _(*4)

erfans_maintenance:
    resource: "@ErfansMaintenanceBundle/Resources/config/routing.yml"

if you want to use your own controller and action for maintenance page or use some external links or just use an html page then you can skip this part., _(*5)

Step 4: Configuration

To check if current request is under maintenance this bundle will check a list of defined "include/exclude" rules in the bundle configuration. This approach will provide maximum flexibility to put a part of your website in the maintenance mode or just exclude some pages from the maintenance., _(*6)

To add a "include" rule set parameter "rule" to "+" and to add an exclude rule set "rule" to "-". Available parameters for each rule are:, _(*7)

rule: # One of "+"; "-", Required
env:  # Requested environment e.g. "test" or ["dev", "prod"]
path: # Regular expression for request path e.g. ^/* to cover all requests
routes: # To compair with requested route e.g. ["home_route"]
host: # Requested host
schemes: # e.g. http or https 
methods: # Requested method e.g. ["get", "post"]
usernames: # Username of the current user            
roles: # Roles of the current user               
ips: # IP of the visitor                

The default rules are:, _(*8)

rules:
    - {rule: '+', path: '^/*'} # include all paths into maintenance mode
    - {rule: '-', path: '^/login$'} # exclude usual path for login from the maintenance
    - {rule: '-', roles: ['ROLE_ADMIN']} # exclude Admin role from the maintenance
    - {rule: '-', env: ['test', 'dev']} # exclude environments "test" and "dev" from the maintenance 

Defining rules may seems too much effort for this simple task, however, it is handy when you want to develop new parts of the website without interfering other parts., _(*9)

Default configuration for "ErfansMaintenanceBundle":, _(*10)

erfans_maintenance:
    enabled:              false

    # After due-date maintenance mode will not invoke anymore. Date format should be 'YYYY-MM-DD' or 'YYYY-MM-DD HH:MM:SS' or 'YYYY-MM-DD HH:MM:SS +/-TT:TT' or timestamp
    due_date:             null # Example: 2016-7-6 or 2016-7-6 10:10 or 2016-7-6 10:10:10 +02:00 or 1467763200

    # It is possible to change corresponding controller by changing the route name.
    maintenance_route:    erfans_maintenance_maintenance

    # Maintenance page can be an external link or only an html page.
    maintenance_url:      ~

    # View parameters will set on default twig template of maintenance bundle. These values will translate before rendering
    view:
        title:                erfans.maintenance.messages.under_construction.title
        description:          erfans.maintenance.messages.under_construction.description

    # To provide maximum flexibility to put part of website on maintenance mode by defining 'include' or 'exclude' rules.
    rules:                # Example: - {rule: '+', path: '^/*'} # to set maintenance mode for whole website
        - {rule: '+', path: '^/*'}           # include all paths into maintenance mode
        - {rule: '-', path: '^/login$'}      # exclude usual path for login from maintenance
        - {rule: '-', roles: ['ROLE_ADMIN']} # exclude Admin role from maintenance
        - {rule: '-', env: ['test', 'dev']}  # exclude environments "test" and "dev" from maintenance

    # By enabling "redirect_on_normal" website will redirect from maintenance page if maintenance mode is disabled.
    redirect_on_normal:
        enabled:              true

        # Application will redirect from maintenance page to this url if maintenance_mode is false. You can only set one of redirect_url or redirect_route
        redirect_url:         /
        redirect_route:       ~
