Question

我使用厨师和流浪汉作为供应者。

当我尝试按如下方式安装gem时，应用程序崩溃了：

metadata.rb

gem 'faraday'
gem 'json'

default.rb

require 'faraday'
require 'json'

conn = Faraday.new(:url => 'http://127.0.0.1:8200')

此错误引发：

似乎缺少gcc，但我无法安装它，因为它首先尝试安装gems然后执行配方，所以它在我可以做任何事情之前崩溃。

- 编辑 -

我添加了这些行并且正在运行：

metadata.rb :(从这里删除gem依赖）

depends 'hashicorp-vault', '~> 2.5.0'
depends 'build-essential', '~> 8.0.3'

default.rb：

include_recipe 'hashicorp-vault::default'
chef_gem 'faraday'
chef_gem 'json'
require 'faraday'
require 'json'

Answer 1

Chef-y安装gcc的方法是使用build-essential食谱。

Answer 2

在自定义主厨配置之前添加shell配置程序？

例如，在您的Vagrant文件中：

Vagrant.configure("2") do |config|
    config.vm.provision :shell, inline: 'yum install -y gcc'
    config.vm.provision :chef, inline: '...'
end

Answer 3

食谱完全能够运行任意命令，所以如果你知道如何手动操作，你可以在厨师的帮助下完成。话虽如此，你应该保护任何任意命令，这样它们就不会在每次配方运行时运行，只有在需要它们时才会运行。

execute 'sudo yum groupinstall \'Development Tools\'' unless <your logic for 
detecting gcc goes here>

Chef还有Ohai在开始运行之前收集有关运行的元数据，包括您正在运行的操作系统，因此您可以通过利用它来使您的配方成为多平台。

https://docs.chef.io/dsl_recipe.html

include_recipe 'mycookbook::debian' if node['platform_family'] == 'debian'
include_recipe 'mycookbook::rhel' if node['platform_family'] == 'rhel'

或者，如果您计划拥有多种平台类型，那么为您提供更多灵活性

possible_platforms = ['debian', 'rhel']
if possible_platforms.contains? node['platform_family']
   include_recipe "mycookbook::node['platform_family']"
else
    puts 'This platform isn't valid'
end

安装宝石时厨师崩溃了
