集成omnibus-ctl 开发一个专业的软件包管理工具

前边有转发过来自chef 团队的一篇omnibus-ctl 介绍文章，以下尝试进行项目试用

就是简单的集成，没有多少复杂的操作

环境准备

• ruby
  ruby 使用2.6.3 使用 rbenv 安装，可以参考rbenv mac&&linux 安装简单说明
• bundle
  bundler 的安装可以直接使用gem，其他途径存在版本的问题，安装方法

gem install bundler

• 可选配置gem source

gem source -r https://rubygems.org/

gem source -a https://gems.ruby-china.com/

• 安装omnibus

  脚手架模式

gem install omnibus

简单项目集成omnibus-ctl

项目是一个简单的模拟gitlab 的软件包，没有多少操作

• 初始化项目

omnibus new gitlab

• 项目结构

• 说明
  以上config/software/gitlab-ctl.rb ，files/gitlab-ctl-commands 是添加的文件
• 代码说明
  Gemfile 因为需要集成omnibus-ctl 所以需要引用gem 包,我修改了source 为国内的

source 'https://gems.ruby-china.com/'

# Install omnibus

gem 'omnibus', '~> 6.0'

# gem 'omnibus-ctl', '~> 0.6.0'

gem 'omnibus-software', git: 'https://github.com/chef/omnibus-software.git'

# Use Chef's software definitions. It is recommended that you write your own

# software definitions, but you can clone/fork Chef's to get you started.

# gem 'omnibus-software', github: 'chef/omnibus-software'

​

# This development group is installed by default when you run `bundle install`,

# but if you are using Omnibus in a CI-based infrastructure, you do not need

# the Test Kitchen-based build lab. You can skip these unnecessary dependencies

# by running `bundle install --without development` to speed up build times.

group :development do

  # Use Berkshelf for resolving cookbook dependencies

  gem 'berkshelf'

​

  # Use Test Kitchen with Vagrant for converging the build environment

  gem 'test-kitchen'

  gem 'kitchen-vagrant'

end

build do

  block do

    open("#{install_dir}/embedded/bin/gitlab-ctl", "w") do |file|

      file.print <<-EOH

#!/bin/bash

​

# Ruby environment if gitlab-ctl is called from a Ruby script.

  unset $ruby_env_var

done

​

       EOH

    end

  end

​

  command "chmod 755 #{install_dir}/embedded/bin/gitlab-ctl"

​

  # additional omnibus-ctl commands

  sync "#{project_dir}/", "#{install_dir}/embedded/service/omnibus-ctl/"

end

files/gitlab-ctl-commands 自定义命令：

add_command 'config', 'reconfig for gitlab server', 1 do |cmd_name|

      puts 'run config'

      reconfigure

  end

运行&&测试

• 初始化依赖

bundle install --binstubs

• 构建

sudo bin/omnibus build gitlab

• 使用gitlab-ctl
  因为打包制作的比较简单，配置path 路径我们就可以直接使用gitlab-ctl 了

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

使用命令：

gitlab-ctl

I don't know that command.

/opt/gitlab/embedded/bin/omnibus-ctl: command (subcommand)

config

  reconfig for gitlab server

General Commands:

  cleanse

    Delete *all* my data, and start from scratch.

  help

    Print this help message.

  reconfigure

    Reconfigure the application.

  show-config

    Show the configuration that would be generated by reconfigure.

  uninstall

    Kill all processes and uninstall the process supervisor (data will be preserved).

Service Management Commands:

  graceful-kill

    Attempt a graceful stop, then SIGKILL the entire process group.

  hup

    Send the services a HUP.

  int

    Send the services an INT.

  kill

    Send the services a KILL.

  once

    Start the services if they are down. Do not restart them if they stop.

  restart

    Stop the services if they are running, then start them again.

  service-list

    List all the services (enabled services appear with a *.)

  start

    Start services if they are down, and restart them if they stop.

  status

    Show the status of all the services.

  stop

    Stop the services, and do not restart them.

  tail

    Watch the service logs of all enabled services.

  term

    Send the services a TERM.

 

• 说明
  可以看出我们这样就搞出来了一个和gitlab安装包类似的ctl 了，实际上gitlab 安装包也是集成的omnibus-ctl,只是里面功能更复杂而已。
  通过项目omnibus-gitlab 我们可以了解到更多关于omnibus-ctl 的用法
