A Capistrano extension for Magento 2 deployments. Takes care of specific Magento 2 requirements and adds tasks specific to the Magento 2 application. Supports zero-down deployments based on differences in deployed config.php
and db status as reported by Magento's setup:db:status
CLI command. When themes and scopes have been dumped to config.php
via bin/magento app:config:dump scopes themes i18n
then zero-side-effect pipeline will be utilized such that no database nor cache backend configuration are available during the build process.
The following describes minimum Magento versions supported by releases of this gem. Please use an earlier version to deploy older releases of Magento not supported by the most recent iterations of this gem.
- Version 0.9.x supports deployment of Magento 2.3.0 and later.
- Version 0.7.x supports deployment of Magento 2.1.1 and later.
$ gem install capistrano-magento2
-
Add the following to your project's
Gemfile
:source 'https://rubygems.org' gem 'capistrano-magento2'
-
Execute the following:
$ bundle install
-
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.
-
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 }
-
Configure Capistrano, per the Capistrano Configuration section below.
-
Configure your server(s), per the Server Configuration section below.
-
Deploy Magento 2 to staging or production by running the following command in the
tools/cap
directory:$ cap staging deploy
or
$ cap production deploy
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.
-
Configuring
config/deploy.rb
Update the
:application
and:repo_url
values inconfig/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'
-
Configuring
config/deploy/*.rb
filesCapistrano 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.
-

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_jobs, '$(nproc)'
set :magento_deploy_themes, ['Magento/backend', 'Magento/blank']
set :magento_deploy_languages, ['en_US', 'en_CA']
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'
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.
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
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.
When doing atomic deployments with php-opcache installed on a server, the cache will reach a full state after which application performance will degrade as a result of the opcache not being able to do it's job. To work nicely with this, there is support included for automatically resetting the php-opcache after a release is published.
To use this, include require 'capistrano/magento2/cachetool'
in your Capfile
and make sure there is an /etc/cachetool.yml
or /var/www/html/.cachetool.yml
(assuming :deploy_to
points at /var/www/html
) file configured with contents like the following:
adapter: fastcgi
fastcgi: /var/run/php-fpm/www-data.sock
temp_dir: /dev/shm/cachetool
extensions: [ opcache ]
With this configuration in place, be sure cachetool (available from here) has already been installed on the server and is available in $PATH
.
Congratulations! You should now begin to see the pre-deployemnt opcache status information when running a deployment followed immediately be the cachetool opcache:reset
command used to keep things humming nicely along.
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.

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
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 |
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.
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'
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.
