集成omnibus-ctl+ chef 制作一个可配置的软件包

前边有写过使用omnibus-ctl 制作软件包的，但是当时没有集成chef，只有一个空壳子，实际上omnibus-ctl 已经内置
了对于chef 的操作（但是我们还需要在添加一个依赖），以下简单说明两者如何进行集成

demo 是一个类似gitlab-ctl 的操作，但是只有一个简单的cookbook，实际上可以自己进行扩展

项目准备

• 项目初始化

omnibus new gitlab

• 项目结构

  添加了关于cookbook 操作之后的

• 简单说明
  以上就是一个普通的使用omnibus 创建的包项目，同时添加了omnibus-ctl 对于cookbbok 操作的配置以及集成omnibus-ctl

• cookbook
  编写了一个简单的cookbook，可以在执行reconfigure 的时候自动生成需要的文件
  files/gitlab-cookbooks 目录，实际上就是一个简单的chef cookbook 项目，核心是
  使用chef-client local 模式的配置solo.rb 以及dns.json(实际是用模版生成的)
  solo.rb:

CURRENT_PATH = File.expand_path(File.dirname(__FILE__))

TIME = Time.now.to_i

LOG_PATH = '/var/log/gitlab/reconfigure'.freeze

Dir.exist?(LOG_PATH) || FileUtils.mkdir_p(LOG_PATH)

file_cache_path "#{CURRENT_PATH}/cache"

cookbook_path CURRENT_PATH

cache_path "#{CURRENT_PATH}/cache"

verbose_logging false

# Log to the reconfigure log

log_location "#{LOG_PATH}/#{TIME}.log"

log_level :info

dns.json:

{

    "run_list": [ "recipe[dalong::default]" ]

}

完毕！

 

 

• 配置path
  因为是测试，就没有配置使用软连接配置gitlab-ctl,临时方法

export PATH=$PATH:/opt/gitlab/embedded/bin/

• 运行reconfigure

gitlab-ctl reconfigure

效果

gitlab-ctl reconfigure
