deployer-extended-wordpress

What does it do?

This package provides deploy task for deploying WordPress with deployer (deployer.org) and additionally a tasks to synchronize database and media files.

The deployment is simplified in order to have ability to auto-upgrade WordPress and upgrade plugins manually by admin panel (or automatically with tools like InfiniteWP). This is a half way between no deployment at all and deployment fully driven by composer. If you want to manage WordPress and plugins fully with composer then check https://roots.io/ and sourcebroker/deployer-extended-wordpress-composer.

Should I use "deployer-extended-wordpress" or "deployer-extended-wordpress-composer"?

In sourcebroker/deployer-extended-wordpress the WordPress and third party plugins are installed manually. What you have in GIT is basically only your theme/plugins/muplugins. The good thing is that in such case you can update WordPress and plugins automatically. This can be considered as preferable for low budget WordPress websites.

In sourcebroker/deployer-extended-wordpress-composer the WordPress and third party plugins are installed using composer. This way you gain more control over what is installed but at the same time to install new WordPress or new plugin version you need first to modify composer.json or do composer update (depending how big upgrade you do). Then you need to commit composer.json / composer.lock and do deploy which will install new version of WordPress and plugins. This is additional work that can not be easily automated. One of additional advantages of this solution is that you can easily cleanup infected WordPress/plugins files as with each deployment all php files are fresh (part from your GIT and part from composer repositories).

Dependencies

This package depends on following packages:

• sourcebroker/deployer-extended

  Package which provides some deployer tasks that can be used for any framework or CMS.
• sourcebroker/deployer-extended-database

  Package which provides some php framework independent deployer tasks to synchronize database.
• sourcebroker/deployer-extended-media

  Package which provides some php framework independent deployer tasks to synchronize media.
• wp-cli/search-replace-command

  Package to change domains after database synchronization. Part of wp-cli/wp-cli utility.

Installation

1. Install package with composer:

   composer require sourcebroker/deployer-extended-wordpress
   

2. If you are using deployer as composer package then just put following line in your deploy.php:

   new \SourceBroker\DeployerExtendedWordpress\Loader();
   

3. If you are using deployer as phar then put following lines in your deploy.php:

   require __DIR__ . '/vendor/autoload.php';
   new \SourceBroker\DeployerExtendedWordpress\Loader();
   

4. Remove task "deploy" from your deploy.php. Otherwise you will overwrite deploy task defined in deployer/deploy/task/deploy.php

5. Example deploy.php file:

   <?php
   
   namespace Deployer;
   
   require __DIR__.'/vendor/autoload.php';
   
   new \SourceBroker\DeployerExtendedWordpress\Loader();
   
   set('repository', 'git@my-git:my-project.git');
   
   host('live')
       ->hostname('example.com')->port(22)
       ->user('deploy')
       ->set('shared_files', array_merge(get('shared_files'), ['config/.env.live.local']))
       ->set('public_urls', ['https://www.example.com/'])
       ->set('deploy_path', '/var/www/example.com/live');
   
   host('beta', '111.111.111.111')
       ->hostname('example.com')->port(22)
       ->user('deploy')
       ->set('shared_files', array_merge(get('shared_files'), ['config/.env.beta.local']))
       ->set('public_urls', ['https://beta.example.com/'])
       ->set('deploy_path', '/var/www/example.com/beta');
   
   host('local')
       ->set('public_urls', ['https://example-com.dev/'])
       ->set('deploy_path', getcwd());
   

Mind the declaration of host('local'); Its needed for database tasks to declare domain replacements, and path to store database dumps.

Project's folders structure

This deployment has following assumptions:

1. WordPress source code is not in GIT in order to have ability to easily upgrade them from admin panel.

2. wp-content/plugins should be most out of GIT to in order to have ability to easily upgrade them from admin panel. You can have however some plugins in GIT if you like.

3. wp-content/mu-plugins can be partially out of GIT but you can also have plugins there which are in GIT.

4. config/environments and use of wp-config and .env idea is back ported from bedrock and extended with idea of symfony/dotenv

5. Taking the above points into consideration the only files in GIT will be:

   /config/environments/development.php
   /config/environments/staging.php
   /config/application.php
   /config/.env
   /config/.env.beta
   /config/.env.dev
   /config/.env.live
   /config/.env.dev.local.dist
   /config/.htaccess
   /wp-content/plugins/my-plugin-in-git
   /wp-content/mu-plugins/my-mu-plugin.php
   /wp-content/themes/my-theme/
   .gitignore
   deploy.php
   composer.lock
   composer.json
   wp-config.php
   

Mind .env.beta, .env.dev, .env.live - those files stores data which is specific per instance but can be stored in git. For example database name, database user, database host, SMTP settings (without password). The passwords should be stored in file which is out of git on each of the instance host .env.beta.local, .env.dev.local, .env.live.local or if you do not mind so much about security you can store them also in git.

You need also to add shared local env file per instance. You can do it like this. Look at line 4:

host('live')
 ->hostname('example.com')->port(22)
 ->user('deploy')
 ->set('shared_files', array_merge(get('shared_files'), ['config/.env.live.local']))
 ->set('public_urls', ['https://www.example.com/'])
 ->set('deploy_path', '/var/www/example.com/live');

The only required, out of git file on instance is /config/.env.local where you set info what instance it is. The content of /config/.env.local should be only WP_INSTANCE='live' etc depending on which instance it is.

Look at sourcebroker/wordpress-starter for example how you can use in your WordPress.

The shared dirs defined in deployer/set.php are:

set('shared_dirs', [
        'wp-content/uploads',
        'wp-content/languages',
        'wp-content/upgrade',
    ]
);

The shared files defined in ``deployer/set.php``are:

set('shared_files', [
    '.htaccess',
    'config/.env.local',
]);

Composer

You can set proper version of composer with composer_channel (values: 1, 2, stable, prelive, snapshot) or with composer_version which takes exact tags as arguments (https://github.com/composer/composer/tags). For stability and security its advised that you set composer_channel with value 1 or 2 so it will be automatically updated but will not install any new major version in future so your deploy will remain fairly stable.

set('composer_channel', 2);

Synchronizing database

Database synchronization is done with sourcebroker/deployer-extended-database. Example of command for synchronizing database from live to local instance:

dep db:pull live

Domain replacement

The "post_command" task "db:import:post_command:wp_domains" will change domains declared in "public_urls". Domain replacement is done with cli command "search-replace" from wp-cli/wp-cli.

Please mind to have the same amount of "public_urls" for each of instances because replacement on domains is done for every pair of corresponding urls.

Look at following example to give you idea:

host('live', '111.111.111.111')
    ->hostname('example.com')->port(22)
    ->user('deploy')
    ->set('shared_files', array_merge(get('shared_files'), ['config/.env.live.local']))
    ->set('public_urls', ['https://www.example.com', 'https://sub.example.com'])
    ->set('deploy_path', '/var/www/example.com.live');

host('beta', '111.111.111.111')
    ->hostname('example.com')->port(22)
    ->user('deploy')
    ->set('shared_files', array_merge(get('shared_files'), ['config/.env.live.local']))
    ->set('public_urls', ['https://beta.example.com', 'https://beta-sub.example.com'])
    ->set('deploy_path', '/var/www/example.com.beta');

host('local')
    ->set('public_urls', ['https://example-com.dev', 'https://sub-example-com.dev'])
    ->set('deploy_path', getcwd());

The if you will do:

dep db:pull live

the following commands will be done automatically after database import:

wp search-replace https://www.example.com https://example-com.dev
wp search-replace https://sub.example.com https://sub-example-com.dev

Configuration

Mind that "deploy.php" file must be the same on all instance before you can start to do database synchronization.

Synchronizing media & WordPress / plugins code

Media synchronization is done with package sourcebroker/deployer-extended-media. The command for synchronizing media & php files which are out of git is:

dep media:pull live

Because we do not use composer to get WordPress and plugins therefore we will treat here code of WordPress and plugins as kind of media to synchronize. This is a bit o misuse of sourcebroker/deployer-extended-media but if we think of media as part of project which is out of git that needs to be synchronized between instances then our WordPress and plugins php code which is also out of git is bunch of files that needs to be synchronized between instances.

Therefore our config to synchronize files media & WordPress / plugins code looks like this:

set('media',
    [
        'filter' => [
            '+ /wp-content/',
            '- /wp-content/mu-plugins/*',
            '- /wp-content/themes/*',
            '+ /wp-content/**',
            '+ /wp-admin/',
            '+ /wp-admin/**',
            '+ /wp-includes/',
            '+ /wp-includes/**',
            '+ .htaccess',
            '+ wp-activate.php',
            '+ wp-blog-header.php',
            '+ wp-comments-post.php',
            '+ wp-config-sample.php',
            '+ wp-config.php',
            '+ wp-cron.php',
            '+ wp-links-opml.php',
            '+ wp-load.php',
            '+ wp-login.php',
            '+ wp-mail.php',
            '+ wp-settings.php',
            '+ wp-signup.php',
            '+ wp-trackback.php',
            '+ xmlrpc.php',
            '+ index.php',
            '- *'
        ]
    ]);
