Introduction

ZFDeploy is a command line tool to deploy Zend Framework 2 applications.

This tool produces a file package ready to be deployed. The tool supports the following format: ZIP, TAR, TGZ (.TAR.GZ), .ZPK (the deployment file format of Zend Server 6).

Requirements

Please see the composer.json file.

Installation

ZFDeploy may be installed in two ways: as a standalone, updatable phar file, or via Composer.

Standalone PHAR installation

The standalone phar file is available at:

You can retrieve it using any of the following commands.

Via curl:

$ curl -o zfdeploy.phar https://packages.zendframework.com/zf-deploy/zfdeploy.phar

Via wget:

$ wget https://packages.zendframework.com/zf-deploy/zfdeploy.phar

Or using your installed PHP binary:

$ php -r "file_put_contents('zfdeploy.phar', file_get_contents('https://packages.zendframework.com/zf-deploy/zfdeploy.phar'));"

Once you have the file, make it executable; in Unix-like systems:

$ chmod 755 zfdeploy.phar

You can update the phar file periodically to the latest version using the self-update command:

$ zfdeploy.phar self-update

Composer installation

Run the following composer command:

$ composer require "zfcampus/zf-deploy:~1.0-dev"

Alternately, manually add the following to your composer.json, in the require section:

"require": {
    "zfcampus/zf-deploy": "~1.0-dev"
}

And then run composer update to ensure the module is installed.

If installed via composer, the script lives in vendor/bin/zfdeploy.php of your application.

Usage

Note

If you clone this project standalone, the script is located in bin/zfdeploy.php. If you install this repository as a Composer dependency of your project, the script is located in vendor/bin/zfdeploy.php. If you install using the phar file, you will either need to put it on your path or provide the full path to the phar file; the script name then is zfdeploy.phar.

Depending on your environment, you may need to execute the phar file or php script using your php executable:

$ php bin/zfdeploy.php
$ php vendor/bin/zfdeploy.php
$ php zfdeploy.phar

In most Unix-like systems, if you have /usr/bin/env available, both the script and phar file should be self-executable.

For our examples, we will reference the script as zfdeploy, regardless of how you installed it or how you determine you will need to execute it.

The command line tool can be executed using the following command:

$ zfdeploy build <package>

where <package> is the filename of the output package to produce. When run with no other arguments, it assumes the current directory should be packaged; if you want to specify a different directory for packaging, use the --target flag:

$ zfdeploy build <package> --target path/to/application

You can specify the file format directly in the <package> using the proper extension (e.g. application.zip will create a ZIP file).

zfdeploy includes the following commands:

$ zfdeploy
ZFDeploy, version 0.3.0-dev

Available commands:

 build          Build a deployment package
 help           Get help for individual commands
 self-update    Updates zfdeploy.phar to the latest version
 version        Display the version of the script

The full syntax of the build command includes:

Usage:
 build <package> [--target=] [--modules=] [--vendor|-v]:vendor [--composer=] [--gitignore=] [--deploymentxml=] [--zpkdata=] [--version=]

Arguments:
 <package>      Name of the package file to create; suffix must be .zip, .tar, .tar.gz, .tgz, or .zpk
 --target       The target directory of the application to package; defaults to current working directory
 --modules      Comma-separated list of modules to include in build
 --vendor|-v    Whether or not to include the vendor directory (disabled by default)
 --composer     Whether or not to execute composer; "on" or "off" ("on" by default)
 --gitignore    Whether or not to parse the .gitignore file to determine what files/folders to exclude; "on" or "off" ("on" by default)
 --configs      Path to directory containing application config files to include in the package
 --deploymentxmlPath to a custom deployment.xml to use when building a ZPK package
 --zpkdata      Path to a directory containing ZPK package assets (deployment.xml, logo, scripts, etc.)
 --version      Specific application version to use for a ZPK package

This deployment tool takes care of the local configuration files, related to the specific environment, using the .gitignore file. If your applications use the .gitignore file to exclude local configuration files, for instance the local.php file in the /config/autoload folder, ZFdeploy will not include these files in the deployment package. You can disable the usage of the .gitignore file using the --gitignore off option.

NOTE: if you disable the .gitignore usage

If you disable the .gitignore using the --gitignore off option, all the files of the ZF2 application will be included in the package. That means local configuration files, including sensitive information like database credentials, are deployed in production!!! Please consider this behaviour before switching off the gitignore option.

Another important part of the deployment of a ZF2 application is the usage of composer.

ZFDeploy executes the following composer command during the creation of the deployment package:

$ php composer.phar install --no-dev --prefer-dist --optimize-autoloader

The --no-dev flag ensures that development packages are not installed in the production environment. The --prefer-dist option tell composer to install from dist if possible. This can speed up installs substantially on build servers and other use cases where you typically do not run updates of the vendors The --optimize-autoloader flag makes Composer's autoloader more performant by building a "class map".

For more information about Composer, you can read the Documentation page of the project.

Note: production configuration

Zend Framework 2 applications often include {,*.}local.php files in config\autoload/, which are used to provide environment specific configuration. (In Apigility, this may include database configuration, Authentication configuration, etc.). These files are omitted from version control via .gitignore directives -- and, by default, from packaging.

The settings you want for production will often differ from those in your development environment, and you may push them to production in a variety of ways -- via Chef, Puppet, Ansible, etc. Another option is to use the --configs flag when building your package. You can pass a directory containing production configuration files, and these will then be included in your deployment package.

Getting help

The help command can list both the available commands, as well as provide the syntax for each command:

  • zfdeploy help will list all commands available.
  • zfdeploy help <command> will show usage for the named command.
