Liquid Light Deployer

This package is used by Liquid Light to deploy TYPO3 websites via CI - specifically Gitlab.

---

It is best used within Gitlab CI as it can utilise several environment variables.

The basis for this is PHP Deployer, however a lot of functionality comes from deployer-extended-typo3 and it's many meta-packages.

Options

There are several settings defined by default within this package for the most common hosts.

Hosts

Set the hostname of the server in the deploy.php file - the rest of the connection details should be in your .ssh/config file

host('production')
  ->set('hostname', 'client.xxx')
;

Existing Hosts

The following hosts have a config file in the deployer/hosts file with some sensible defaults

• production
• staging
• local

Clearing OPCache

If the server has OPCache installed, it will need to be cleared on each deployment to allow PHP and Apache to see the new symlinks.

To do this, you need to declare an array in public_urls in the deploy file, along with adding the cache:clear_php_http task for the environment.

1. Add ->set('public_urls', ['[URL]']) to the production host in deploy.php
2. Add the cache:clear_php_http task for production instances (example below)

on(select('instance=production'), function ($host) {
	after('cache:clear_php_cli', 'cache:clear_php_http');
});

Pushing the database

Pushing the database to live is prohibited, however there are some cases where this needs to be done.

To allow this, add the following to your local deploy.php file

set('db_allow_push_live', true);

Common settings

VPS

Configuration

Add the following settings if not set (and adjust if necessary). They can be set globally or chained to the host (e.g. ->set('writable_use_sudo', true))

set('writable_use_sudo', true);
set('cleanup_use_sudo', true);
set('writable_mode', 'chgrp');
set('http_group', 'www-data');

Additional tasks

deploy:vps:writable

Add an extra post-deploy task to reset permissions and reboot PHP if needed

after('typo3:cache:flush:pages', 'deploy:vps:writable');

service:php_fpm_reload

Add PHP reloading to set the correct version as documented in deployer-extended

Upgrading

v2 -> v3

As well as removing some functionality, the v3 upgrade requires some changes to the deploy.php file

1. In deploy.php, update the require location & class invocation

<?php

namespace Deployer;

require_once './vendor/autoload.php';
new \LiquidLight\Deployer\Loader();

2. Review each environment and remove the ll_deployer_environment declaration - this doesn't add any tasks or configuration any more
   • Note: If it was set to vps then follow the Common settings -> VPS steps above
