测试厨师角色和环境 [英] Testing Chef roles and environments

问题描述

我是Chef的新手，并且一直使用测试厨房来测试我的菜谱的有效性，效果很好。现在，我要确保在最初运行Chef之前，特定于环境的属性在生产节点上是正确的。这些将在角色中定义。

I'm new to Chef and have been using Test Kitchen to test the validity of my cookbooks, which works great. Now I'm trying to ensure that environment-specific attributes are correct on production nodes prior to running Chef initially. These would be defined in a role.

例如，我有一些食谱可以使用带有开发人员设置的Vagrant框来收敛，从而验证食谱。我希望能够测试生产节点的角色。我想我希望这些测试成为描述我的环境的真实来源。看看Test Kitchen的文档，这似乎超出了范围。

For example, I may have recipes that converge using a Vagrant box with dev settings, which validates the cookbook. I want to be able to test that a production node's role. I think I want these tests as the source of truth describing my environment. Looking at Test Kitchen's documentation, this seems beyond its scope.

我的假设正确吗？在第一次在生产节点上运行Chef之前，是否有更好的方法来测试菜谱以确保它具有正确的设置？

Is my assumption correct? Is there a better approach to test a cookbook before the first time Chef is run on a production node to ensure it has the correct settings?

推荐答案

我很高兴地发现Chef_zero在其厨师存储库中使用了 test / integration目录。

I pleasantly discovered that chef_zero uses the "test/integration" directory as it's chef repository.

注意：

• 供应商是Chef_zero


• 运行列表配置为使用角色

file "/opt/helloworld.txt" do
  content "#{node['demo']['greeting']}"
end

属性/默认值。 rb

attributes/default.rb

default['demo']['greeting'] = "hello world"

注意：

• 没有默认值

require 'spec_helper'

describe file('/opt/helloworld.txt') do

  it { should be_file }
  its(:content) { should match /this came from my role/ }

end

注意：

• 集成测试正在寻找由角色设置的内容属性

{
  "name": "demo",
  "default_attributes": {
    "demo": {
      "greeting": "this came from my role"
    }
  },
  "run_list": [
    "recipe[demo]"

}
