Configuration management tool embedding mruby, which is alternative implementation of Itamae

mitamae

Itamae implementation that is runnable without Ruby, which is a lightweight configuration management tool inspired by Chef. With mitamae's standalone binary, you can write a configuration recipe in Ruby and apply it without Ruby.

Status

All features are implemented and tested.

Synopsis

Like original Itamae, you can manage configuration by Ruby DSL. But mitamae does not require MRI to run.

# cat recipe.rb
include_recipe 'included'

directory '/tmp/etc'

file '/tmp/etc/hello' do
  content 'This is mitamae'
end

template '/tmp/etc/config.yml' do
  source 'config.yml.erb'
end

# cat included.rb
define :vim, options: '--with-lua --with-luajit' do
  package 'vim' do
    version params[:name]
    options params[:options]
  end
end

vim '7.4.1910-1'

service 'mysqld' do
  action [:start, :enable]
end

How to write recipes

See Itamae's reference.

Plugins are implemented differently. See PLUGINS.md for details.

Supported features

itamae ssh is omitted by design because it's slow. If you want to provision a server, download mitamae binary, transfer recipes and execute it over ssh. For that reason, mitamae is more suitable for development environment bootstrap.

In recipes, you can use the features listed below.

• Common Attributes
  • user
  • cwd
  • only_if
  • not_if
  • notifies
  • subscribes
  • verify
• Resources
  • execute resource
  • package resource

  • group resource
  • remote_directory resource
  • http_request resource
  • local_ruby_block resource
• Definitions
• Including Recipes
• Node Attributes

Supported platforms

Currently following platforms are supported but others can be easily supported by porting specinfra modules.

• Alpine Linux
• Amazon Linux
• Arch Linux
• CentOS
• Debian
• Gentoo
• Ubuntu
• macOS
• ...etc
