推荐答案

如果你需要严格的厨师进程中的env var set，可以使用 ENV ['foo'] ='bar '，因为它是一个红宝石进程。

If you need an env var set strictly within the Chef process, you can use ENV['foo'] = 'bar' since it's a ruby process.

如果你需要为执行提供者设置一个，Chef发布环境哈希：

If you need to set one for an execute provider, Chef exposes an environment hash:

execute 'Bootstrap the database' do 
  cwd "#{app_dir}/current"
  command "#{env_cmd} rake db:drop db:create db:schema:load RAILS_ENV=#{rails_env}"
  environment 'HOME' => "/home/#{app_user}"
  user app_user
  action :run
  not_if %[psql -U postgres -c "\\l" | grep #{db_name}]
end

如果您要设置持久环境变量，那么你可能想要厨师编辑 /etc/profile.d/chef.sh ， / etc / environment ，用户个人资料等。

If you're looking to set a persistent environment variable then you may want to have Chef edit /etc/profile.d/chef.sh, /etc/environment, a users' profile, etc.
