如何執行廚師食譜?

  • December 5, 2016

可以使用 Ansible 和 Puppet 安裝軟體,方法是從galaxy 或 puppetforge 下載角色並無主執行。

目標

目的是使用 chef masterless安裝MongoDB 。我只想下載一本食譜並執行它。

試圖

  • knife cookbook site download mongodb3將食譜保存在/home/user/mongodb3-5.3.0.tar.gz
  • 焦油被提取
  • 基於此文件,我嘗試使用 執行食譜chef-client --local -o recipe['mongodb3'],但結果是:

[2016-11-18T10:35:28+01:00] WARN: No config file found or specified on command line, using command line options.

可以使用@TimHaintz 提供的範例執行 Chef 程式碼:

問題

  1. 何時使用knife, chef-apply, chef-client,chef-shellchef-solo?
  2. 從市場上執行食譜的最短方法是什麼?

knife cookbook site download只是給你一個原始的壓縮包,而不是你可以直接與 Chef 一起使用的格式。如果您正在尋找功能齊全的 Chef-solo 工作流程,我會將該knife-solo外掛與 Berkshelf 一起使用。

將要使用的說明書放入Berksfile,然後使用knife solo cook將它們傳送到目標節點並執行chef-solo

@coderanger 建議使用 berkshelf並且在本文件中找到了以下片段:

伯克斯文件

source "https://supermarket.chef.io"

cookbook "terraform"

安裝說明書

user@host ~ $ berks install
Resolving cookbook dependencies...
Fetching cookbook index from https://supermarket.chef.io...
Installing ark (1.1.0)
Installing compat_resource (12.16.2)
Installing seven_zip (2.0.2)
Installing build-essential (7.0.2)
Installing ohai (4.2.2)
Using terraform (0.5.3)
Installing mingw (1.2.4)
Installing windows (2.1.1)

Vendoring seven_zip (2.0.2) to /home/user/berks-cookbooks/seven_zip
Vendoring terraform (0.5.3) to /home/user/berks-cookbooks/terraform
Vendoring windows (2.1.1) to /home/user/berks-cookbooks/windows

以下片段基於此答案

配置文件

cookbook_path [
 '/home/user/berks-cookbooks'
]

配置文件

{
 "run_list": [
   "terraform"
 ]
}

sudo chef-solo -c config.rb -j config.json
