除了_default之外，对于chef_environment的嘲讽会让404分开

Posted 2021-05-04

我试图模仿chef_environment，如果我尝试模拟_default厨师环境，我已经成功了。但是一旦我用不同的环境变量编写上下文块，我就会收到404错误

我有stg和_default厨师环境。但我没有使用_default环境，所以它的default_attributes列表和其他东西都是空的。那么_default工作的原因是什么，而所有其他环境都给出了错误？

下面是我的user_rspec.rb文件： -

 require 'ChefSpec'
 require 'spec_helper'

 describe 'base::users' do
   let(:chef_run) do
     ChefSpec::ServerRunner.new(platform: 'amazon', version: '2017.09') do |node|
       env = Chef::Environment.new
       env.name environment # using a variable here so we can change it in other contexts
       allow(node).to receive(:chef_environment).and_return(env.name)
       allow(Chef::Environment).to receive(:load).and_return(env)
     end.converge(described_recipe)
   end

   context 'When all attributes are default, on an amazon 2017.09 with _default end' do
     let(:environment) { '_default' }

     it 'converges successfully' do
       expect{ chef_run }.to_not raise_error
     end

     it "create devops group" do
         expect(chef_run).to create_users_manage('devops').with(group_id: 3000)
     end

     it "assign sudo permission to devops-trainee on _default env" do
         expect(chef_run).to create_sudo('devops-trainee')
     end

   end

   context 'When all attributes are default, on an amazon 2017.09 with stg env' do
     let(:environment) { 'stg' }

     it "don't assign sudo permission to devops-trainee on stg env" do
         expect(chef_run).not_to create_sudo('devops-trainee')
     end

   end


 end

产量

答案

好吧，我在上面的例子中发现了问题。

我使用ChefSpec :: ServerRunner而不是SoloRunner，上面的东西只适用于solo runner。

对于ServerRunner，您必须执行以下操作。

  let(:chef_run) do
    ChefSpec::ServerRunner.new(platform: 'amazon', version: '2017.09') do |node, server|
      server.create_environment(environment)
      node.chef_environment = environment
    end.converge(described_recipe)
  end
