What does it do?

Library with some additional tasks for deployer (deployer.org).

Setting's documentation

composer_version

Install specific composer version. Use tags. Valid tags are here https://github.com/composer/composer/tags . Default value is null.

composer_channel

Install latest version from channel. Set this variable to '1' or '2' (or 'stable', 'snapshot', 'preview'). Read more on composer docs. Default value is stable which will install latest version of composer. If you need stability set it better to '1' or '2'.

composer_channel_autoupdate

If set then on each deploy the composer is checked for latest version according to composer_channel settings. Default value is true.

web_path

Path to public when not in root of project. Must be like "pub/" so without starting slash and with ending slash.

Task's documentation

deploy

deploy:check_branch

Check if the branch you want to deploy is different from the branch currently deployed on host. If you have information that the branch on the host is different than the branch you want to deploy then you can take decision to overwrite it or not.

deploy:check_branch_local

Check if the branch you are currently checked out on your local is the same branch you want to deploy. The deploy.php files on both branches can be different and that can influence the deploy process.

deploy:check_composer_install

Check if there is composer.lock file on current instance and if its there then make dry run for "composer install". If "composer install" returns information that some packages needs to be updated or installed then it means that probably developer pulled composer.lock changes from repo but forget to make "composer install". In that case deployment is stopped to allow developer to update packages, make some test and make deployment then.

deploy:check_composer_validate

Check if composer.lock file is up to date with current state of composer.json. In not then deployment is stopped.

deploy:check_lock

Checks for existence of file deploy.lock in root of current instance. If the file deploy.lock is there then deployment is stopped.

You can use it for whatever reason you have. Imagine that you develop css/js locally with "grunt watch". After you have working code you may forget to build final js/css with "grunt build" and you will deploy css/js that will be not used on production which reads compiled css/js.

To prevent this situation you can make "grunt watch" to generate file "deploy.lock" (with text "Run 'grunt build'." inside) to inform you that you missed some step before deploying application.

file

file:backup

Creates backup of files. Single task may perform multiple archivization using defined filters. Old ones are deleted after executing this task. Default limit is 5.

Configuration description

• file_backup_packages

  required: yes

  default value: none

  type: array

  
  

  Packages definition
• file_backup_keep

  required: no

  default value: 5

  type: int

  
  

  Limit of backups per package

Sample configuration:

set('file_backup_packages', [
    'config' => [
        '-path "./etc/*"',
    ],
    'translations' => [
        '-path "./l10n/*"',
        '-path "./modules/*/l10n/*"',
    ],
    'small_images' => [
        [ '-path "./media/uploads/*"', '-size -25k' ],
        [ '-path "./media/theme/*"', '-size -25k' ],
    ],
]);

set('file_backup_keep', 10);

Config variable file_backup_packages stores information about backup packages and files filtering options. Each package defines filters which will be used in find command. First level element are groups which will be concatenated using logical alternative operator operator OR. If group is array type then group elements will be concatenated using logical conjunction operator.

Package config: It is simplest definition. For this package all files from directory "./etc/" will be backuped.

Package translations: For this one all files from directory "./l10n/" will be backuped. It will also include files from all "l10n/" from "modules" subdirectory. For example "modules/cookies/l10n"

Package small_images: This one will contain all small (smaller than 25kB) files from "media/uploads" and "media/theme".

As you can see file_backup_keep is set to 10 which means only newest 10 backups per package will be stored.

file:copy_dirs_ignore_existing

Copy directories from previous release except for those directories which already exists in new release.

file:copy_files_ignore_existing

Copy files from previous release except for those files which already exists in new release.

file:upload_build

Upload files not defined in clear_paths, shared_files, shared_dirs. Can be used as good default for uploading build from CI.

cache

cache:clear_php_cli

This task clears the file status cache, opcache and eaccelerator cache for CLI context.

cache:clear_php_http

This task clears the file status cache, opcache and eaccelerator cache for HTTP context. It does following:

1. Creates file "cache_clear_[random].php" in "{{deploy_path}}/current" folder.
2. Fetch this file with selected method - curl / wget / file_get_contents - by default its wget.
3. The file is not removed after clearing cache for reason. It allows to prevent problems with realpath_cache. For more info read http://blog.jpauli.tech/2014-06-30-realpath-cache-html/

You must set public_urls configuration variable so the script knows the domain it should fetch the php script. Here is example:

server('prelive', 'example.com', 22)
  ->user('deploy')
  ->stage('prelive')
  ->set('deploy_path', '/home/web/html/www.example.com.prelive')
  ->set('public_urls', ['https://prelive.example.com']);

Task configuration variables:

• cache:clear_php_http:phpcontent

  required: no

  type: string

  default value:

  <?php
    clearstatcache(true);
    if(function_exists('opcache_reset')) opcache_reset();
    if(function_exists('eaccelerator_clear')) eaccelerator_clear();
  

  
  

  Php content that will be put into dynamically created file that should clear the caches.

  
  
• public_urls

  required: yes

  default value: none

  type: array

  
  

  Domain used to prepare url to fetch clear cache php file. Its expected to be array so you can put there more than one domain and use it for different purposes but here for this task the first domain will be taken.

  
  
• fetch_method

  required: no

  default value: wget

  type: string

  
  

  Can be one of following value:

  - curl,

  - file_get_contents

  
  
• cache:clear_php_http:timeout

  required: no

  default value: 15

  type: integer

  
  

  Set the timeout in seconds for fetching php clear cache script.
