capistrano-shared-file

A Capistrano recipe to upload, download and symlink configuration files like config/database.yml to or from your remote servers.

One of the most common use cases for this gem is when used together with Figaro, where the config/application.yml file is git-ignored but you still want to have a convenient way to push it to your servers on every deploy.

Heavily inspired by teohm's capistrano-shared_file gem.

Install

gem install capistrano-shared-file

For Bundler, add this to your Gemfile:

gem 'capistrano-shared-file'

Usage

You can start using it by simply adding the line below at the bottom of your deploy.rb:

require 'capistrano-shared-file'

Generally you won't need to modify any of the default variables defined in the gem. For a more customized setup, please refer to the next section.

Variables

The following is the list of capistrano variables that are defined in this gem and that can be customized to fit your specific needs.

shared_files

Specifies the list of files that you want to symlink to the current_release directory. By default:

set :shared_files, %w(config/database.yml)

For example, when using Figaro you will probably want to add the application.yml file to this list.

set :shared_files, %w(config/database.yml config/application.yml)

shared_file_dir

Specify the directory in which you want to upload all shared files. By default:

set :shared_file_dir, 'files'

For example, given the following variables are set in your deploy.rb:

set :deploy_to,       '/home/damselem/my_amazing_project
set :shared_file_dir, 'files'
set :shared_files,    %w(config/application.yml)

The shared file in the remote will be at:

/home/damselem/my_amazing_project/shared/files/config/application.yml

shared_file_backup

Enbales backups of your shared files when uploading and downloading shared files. By default:

set :shared_file_backup, false

For more details on the implications of setting this variable to true, refer to the next Upload and Download sections.

Tasks

Upload

To upload all the files defined in the shared_files capistrano variable to a remote server, you can execute:

bundle exec cap shared_file:upload

With backup (it creates a backup of the remote shared files on your machine before uploading the new versions to the remote machine):

bundle exec cap shared_file:upload -S shared_file_backup=true

Download

To download all the files defined in the shared_files capistrano variable from a remote server, you can execute:

bundle exec cap shared_file:download

With backup (it creates a backup of the local shared files on your machine before downloading the new versions from the remote machine):

bundle exec cap shared_file:download -S shared_file_backup=true

Symlink

To symlink the uploaded configuration files to the current release path, you can execute:

bundle exec cap shared_file:symlink

You normally shouldn't have to execute it manually since it's already executed automatically on every deploy.

capistrano/ext/multistage

This gem has been tested to work with capistrano/ext/multistage. For example:

bundle exec cap <STAGE> shared_file:upload
bundle exec cap <STAGE> shared_file:download
