TenantBundle

Allows separate Symfony environments per tenant, _(*1)

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:, _(*2)

$ composer require vivait/tenant-bundle

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation., _(*3)

Step 2: Enable the Bundle

Then, enable the bundle by adding the following line in the app/AppKernel.php file of your project:, _(*4)

<?php
// app/AppKernel.php

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

            new Vivait\TenantBundle\VivaitTenantBundle(),
        );

        // ...
    }

    // ...
}

Step 3: Altering your kernel to be tenanted

Because a kernel environment is immutable, we need to decipher the tenant before booting the kernel. We have created a tenanted kernel for your AppKernel to extend, which acts as a middleware to Symfony's Kernel. When using this middleware, you will need to implement a couple of methods., _(*5)

The first abstract method, getAllTenants is used to return an array of Tenant objects. A number of providers are provided, although this could also implement custom logic, if needed., _(*6)

The second abstract method, getCurrentTenantKey is used to locate the current tenant, so the kernel can alter the environment based on this. A number of locators are provided, although this could also implement custom logic, if needed., _(*7)

Below is an example of the implementation of both of these, and if you're unsure what any of this means, is an advised starting point:, _(*8)

<?php
// app/AppKernel.php

use Symfony\Component\Config\Loader\LoaderInterface;
use Symfony\Component\HttpFoundation\Request;
use Vivait\TenantBundle\Kernel\TenantKernel;
use Vivait\TenantBundle\Locator\HostnameLocator;
use Vivait\TenantBundle\Provider\ConfigProvider;
use Vivait\TenantBundle\Provider\TenantProvider;

// ...
class AppKernel extends TenantKernel
{
    // ...

    /**
     * Provides an array of all Tenants
     *
     * @return Tenant[]
     */
    protected function getAllTenants()
    {
       $configProvider = new ConfigProvider( __DIR__ . '/config/' );
       return $configProvider->loadTenants();
    }

    /**
     * Provides the current tenant's key
     * @param Request $request
     * @return string The current tenant's key
     */
    protected function getCurrentTenantKey( Request $request )
    {
        return HostnameLocator::getTenantFromRequest( $request );
    }
}

Step 4: Creating environments for each tenant

An environment will be automatically created for each tenant by Symfony. However, if you choose to use the default AppKernel::registerContainerConfiguration method, as provided by Symfony, then you will need to create a new config file for each tenant environment. Each tenant environment is prefixed with 'tenant_', so if you have a tenant called 'mytenant', then you'd need to create 'app/config/config_tenant_mytenant.yml'. You can configure this behaviour by changing your AppKernel::registerContainerConfiguration method, but you will also need to customise the patterns used in ConfigProvider to match the change in config structure., _(*9)

You could also use an alternative provider to provide a list of tenants, for example there is a YamlProvider that retrieves a list of tenants from a YAML file., _(*10)

Running commands against tenants

Since each tenant now runs under a separate environment, when updating your application you'll need to run commands such as cache clear or doctrine migrations against each tenant's environment. A special binary has been provided to make this easier and is used by simply prefixing your usual command with the tenant binary:, _(*11)

bin/tenant php app/console cache:clear

This will automatically run the cache clear command against all tenants., _(*12)

Parallel commands & daemons

If you want to run a command in parallel, for example a daemon command, then you can specify this using the -P option:, _(*13)

bin/tenant -P 10 php app/console my:daemon:command

In the example above, this will run the cache clear command for up to 10 tenants in parallel. If you specify -P as 0 then the binary will automatically set the number of processes to match the number of tenants., _(*14)

Specifying specific tenants

You can specify specific tenants to run commands against using the -t option:, _(*15)

bin/tenant -t mytenant,anothertenant php app/console cache:clear

Other options

You can get a full list of options using -h:, _(*16)

bin/tenant -h
