Capistrano::Magento2

A Capistrano extension for Magento 2 deployments. Takes care of specific Magento 2 requirements and adds tasks specific to the Magento 2 application.

Installation

Standalone Installation

$ gem install capistrano-magento2

Using Bundler

1. Add the following to your project's Gemfile:

   source 'https://rubygems.org'
   gem 'capistrano-magento2'

2. Execute the following:

    $ bundle install
   

Usage

1. Install Capistrano in your Magento project:

   $ cd <project_root>
   $ mkdir -p tools/cap
   $ cd ./tools/cap
   $ cap install

Note: By default, Capistrano creates "staging" and "production" stages. If you want to define custom staging areas, you can do so using the "STAGES" option (e.g. cap install STAGES=stage,prod). Built-in notifications (see below) confirm deploy action on both "production" and "prod" area names by default.

2. Update your project's Capfile to look like the following:

   # Load DSL and set up stages
   require 'capistrano/setup'
   
   # Load Magento deployment tasks
   require 'capistrano/magento2/deploy'
   require 'capistrano/magento2/pending'
   
   # Load Git plugin
   require "capistrano/scm/git"
   install_plugin Capistrano::SCM::Git
   
   # Load custom tasks from `lib/capistrano/tasks` if you have any defined
   Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

3. Configure Capistrano, per the Capistrano Configuration section below.

4. Configure your server(s), per the Server Configuration section below.

5. Deploy Magento 2 to staging or production by running the following command in the tools/cap directory:

   $ cap staging deploy

   or

   $ cap production deploy

Default Configuration

Capistrano Configuration

Before you can use Capistrano to deploy, you must configure the config/deploy.rb and config/deploy/*.rb files. This section will cover the basic details for configuring these files. Refer to the Capistrano documentation and README for more details.

1. Configuring config/deploy.rb

   Update the :application and :repo_url values in config/deploy.rb:

   # Something unique such as the website or company name
   set :application, 'example'
   # The repository that hosts the Magento 2 application (Magento should live in the root of the repo)
   set :repo_url, '[email protected]:acme/example-com.git'

2. Configuring config/deploy/*.rb files

   Capistrano allows you to use server-based or role-based syntax. You can read through the comments in the file to learn more about each option. If you have a single application server then the server-based syntax is the simplest configuration option.

   • Single application server

     If your stage and production environments consist of a single application server, your configuration files should look something like this:

     config/deploy/production.rb

     server 'www.example.com', user: 'www-data', roles: %w{app db web}
     
     set :deploy_to, '/var/www/html'
     set :branch, proc { `git rev-parse --abbrev-ref master`.chomp }

     config/deploy/staging.rb

     server 'stage.example.com', user: 'www-data', roles: %w{app db web}
     
     set :deploy_to, '/var/www/html'
     set :branch, proc { `git rev-parse --abbrev-ref develop`.chomp }

   • Multiple application servers

     Refer to the "role-based syntax" comments in the config/deploy/*.rb files or to the Capistrano documentation for details on how to configure multiple application servers.

Magento Deploy Settings

setting	default	what it does
:magento_deploy_setup_role	:all	Role from which primary host is chosen to run things like setup:upgrade on
:magento_deploy_cache_shared	true	If true, cache operations are restricted to the primary node in setup role
:magento_deploy_languages	['en_US']	Array of languages passed to static content deploy routine
:magento_deploy_themes	[]	Array of themes passed to static content deploy (Magento 2.1.1 and later)
:magento_deploy_jobs	4	Number of threads to use for static content deploy (Magento 2.1.1 and later)
:magento_deploy_composer	true	Enables composer install behaviour in the built-in deploy routine
:magento_deploy_production	true	Enables production specific DI compilation and static content generation
:magento_deploy_maintenance	true	Enables use of maintenance mode while magento:setup:upgrade runs
:magento_deploy_confirm	[]	Used to require confirmation of deployment to a set of capistrano stages
:magento_deploy_chmod_d	2770	Default permissions applied to all directories in the release path
:magento_deploy_chmod_f	0660	Default permissions applied to all non-executable files in the release path
:magento_deploy_chmod_x	['bin/magento']	Default list of files in release path to set executable bit on

Example Usage

Add a line similar to the following in config/deploy.rb to set a custom value on one of the above settings:

set :magento_deploy_languages, ['en_US', 'en_CA']

set :magento_deploy_composer, false

Capistrano Built-Ins

For the sake of simplicity in new project setups :linked_dirs and :linked_files are pre-configured per the following.

set :linked_files, [
  'app/etc/env.php',
  'var/.setup_cronjob_status',
  'var/.update_cronjob_status'
]

set :linked_dirs, [
  'pub/media',
  'pub/sitemaps',
  'var/backups', 
  'var/composer_home', 
  'var/importexport', 
  'var/import_history', 
  'var/log',
  'var/session', 
  'var/tmp'
]

If you would like to customize the linked files or directories for your project, you can copy either one or both of the above arrays into the config/deploy.rb or config/deploy/*.rb files and tweak them to fit your project's needs. Alternatively, you can add a single linked dir (or file) using append like this:

append :linked_dirs, 'path/to/link'

Composer Auth Credentials

Magento 2's composer repository requires auth credentials to install. These can be set on target servers in a global composer auth.json file, the project's composer.json or by setting them in your deployment configuration using the following two settings:

set :magento_auth_public_key, '<your_public_key_here>'
set :magento_auth_private_key, '<your_prviate_key_here>'

To obtain these credentials, reference the official documentation on DevDocs: Get your authentication keys

Caution: When using these settings, the values will be logged to the log/capistrano.log file by SSHKit. They will not, however, be included in the general command output by default.

Magento 2 Deploy Routine

A pre-built deploy routine is available out-of-the-box. This can be overriden on a per-project basis by including only the Magento 2 specific tasks and defining your own deploy.rake file under lib/capistrano/tasks in your projects Capistrano install location.

To see what process the built-in routine runs, take a look at the included rake file here: https://github.com/davidalger/capistrano-magento2/blob/master/lib/capistrano/tasks/deploy.rake

Server Configuration

Web Server Root Path

Before deploying with Capistrano, you must update each of your web servers to point to the current directory inside of the configured :deploy_to directory. For example: /var/www/html/current/pub Refer to the Capistrano Structure to learn more about Capistrano's folder structure.

Magento Specific Tasks

All Magento 2 tasks used by the built-in deploy.rake file as well as some additional commands are implemented and exposed to the end-user for use directly via the cap tool. You can also see this list by running cap -T from your shell.

Pending Changes Support

When the line require 'capistrano/magento2/pending' is included in your Capfile per the recommended configuration above, this gem will report changes pending deployment in an abbreviated git log style format. Here is an example:

00:00 deploy:pending:log
      01 git fetch origin
    ✔ 01 dalger@localhost 1.241s
    ✔ 01 dalger@localhost 1.259s
      Changes pending deployment on web1 (tags/2.1.2 -> 2.1):
      f511288 Thu Feb 23 12:19:20 2017 -0600 David Alger (HEAD -> 2.1, tag: 2.1.4, origin/2.1) Magento 2.1.4
      7fb219c Thu Feb 23 12:17:11 2017 -0600 David Alger (tag: 2.1.3) Magento 2.1.3
      570c9b3 Thu Feb 23 12:12:43 2017 -0600 David Alger Updated capistrano configuration
      No changes to deploy on web2 (from and to are the same: 2.1 -> 2.1)

When there are no changes due for deployment to any host, a warning requiring confirmation will be emitted by default:

No changes to deploy on web1 (from and to are the same: 2.1 -> 2.1)
No changes to deploy on web2 (from and to are the same: 2.1 -> 2.1)
Are you sure you want to continue? [y/n]

This confirmational warning can be disabled by including the following in your project's configuration:

set :magento_deploy_pending_warn, false

Pending Changes Configuration

| setting | what it does | -------------------------------- | ------- | --- | :magento_deploy_pending_role | Role to check for pending changes on; defaults to :all | :magento_deploy_pending_warn | Set this to false to disable confirmational warning on zero-change deployments | :magento_deploy_pending_format | Can be used to set a custom change log format; refer to defaults.rb for example

Pending Changes Tasks

cap command	what it does
deploy:pending	Displays a summary of commits pending deployment

Note: For more details including screenshots of what this functionality does, reference this post.

Terminal Notifier on OS X

This gem includes an optional configuration file include which adds notification support via the terminal-notifier gem. To configure notifications, simply add the following line to your Capfile:

require 'capistrano/magento2/notifier'

Notice: The terminal-notifier gem is currently macOS specific and thus can not be used on generic *nix environments. Because this gem has been known to cause ruby stability issues on certain non-macOS environments, it is not specified as a hard requirement in this gem's gemspec. When using this functionality, it is expected the gem either be already present on your working environment or be added to your project's Gemfile:

gem 'terminal-notifier'

Development

After checking out the repo, run bundle install to install dependencies. Make the necessary changes, then run bundle exec rake install to install a modified version of the gem on your local system.

To release a new version, update the version number in capistrano/magento2/version.rb, merge all changes to master, and then run bundle exec rake release. This will create a git tag for the version (the tag will apply to the current HEAD), push git commits and tags, and push the .gem file to rubygems.org.

Note: Releasing a new version of the gem is only possible for those with maintainer access to the gem on rubygems.org.
