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]" ]
}

  • 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

说明

以上就是一个简单的学习,测试,实际上我们将两者集成起来,可以方便的进行软件配置管理
