capistrano-config

capistrano-config

a capistrano recipe to manage configurations files.

Installation

Add this line to your application's Gemfile:

gem 'capistrano-config'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano-config

Usage

This recipes will try to update application config during Capistrano deploy tasks.

To enable this recipe, add following in your config/deploy.rb.

The configuration file config/config.yml will be generated from template in config/templates by default. (The template will be used is either config/templates/config/config.yml.erb or config/templates/config/config.yml.)

# config/deploy.rb
require "capistrano-config"
set :config_files, ["config/config.yml"]

Examples

Setting up shared configuration

You might not want to generate configuration files on everytime of deployment. There is shared mode to generate configuration files just once during deploy:setup.

This is the configuration example for shared configuration mode.

# config/deploy.rb
set :config_use_shared, true
set :config_files, ["config/config.yml"]

The generated configuration files will be installed in #{shared_path}/config/config.yml during deploy:setup. After the setup of shared configuration, symlink will be created at #{release_path}/config/config.yml during deploy.

If you want to update the shared configuration files, invoke config:setup will do that.

% cap config:setup

Setting up local configuration

With some build system, you might need to update some of local files during deployment. There is local mode to help you.

This is the configuration example for local configuration mode.

# config/deploy.rb
set :config_update_locally, true
set :config_files, ["config/config.yml"]

The local configuration files will be updated during deploy.

Setting up files with special parameters

You can set file parameters for each files with defining :config_files as a Hash. The value of Hash will be passed to safe_put of capistrano-file-transfer-ext.

# config/deploy.rb
set :config_files do
  {
    "config/secret.yml" => { :owner => "user", :group => "user", :mode => "640" }
  }
end

If you want to apply for all configuration files, you can use :config_files_options.

config/deploy.rb

set :config_files, ["config/secret.yml", "config/credentials.yml"]
set :config_files_options, :owner => "user", :group => "user", :mode => "640"

Setting up files with absolute paths

If the configuration file name starts with "/", it will be treated as absolute path.

# config/deploy.rb
set :config_files do
  {
    "/etc/init/foo.cnf" => { :configure_except => :local, :owner => "root", :group => "root", :mode => "644", :run_method => :sudo },
  }
end
