ruby - 共享文件夹前的 Vagrant 预配置

Question

在实际创建共享之前，我需要在我的 Vagrantfile 中设置一个用户。我想启动 Vagrant 实例，配置用户，然后设置共享。设置共享后，我想运行更多配置。

我该如何实现？

谢谢!

示例 YAML 配置文件:

centos64:
    ip: "192.168.33.110"
    properties:
        memory: 8192
        cpus: 2
    forwards:
        - host: 8080
          guest: 8080
        - host: 9115
          guest: 9115
    shares:
        repos:
            owner: zenoss
            group: zenoss
            host: "~/repos/zenoss/"
            guest: "/home/zenoss/repos"
    providers:
        virtualbox: "http://puppet-vagrant-boxes.puppetlabs.com/centos-64-x64-vbox4210-nocm.box"
        vmware_fusion: "https://dl.dropbox.com/u/5721940/vagrant-boxes/vagrant-centos-6.4-x86_64-vmware_fusion.box"
    provisions:
        # sets up users and passwords
        - provision: shell
          path: setup_users.sh
          privileged: true
        # installs packages for OS
        - provision: shell
          path: install_packages.sh
          privileged: true
        # update rc files
        - provision: shell
          path: update_rcs.sh
          privileged: true

Vagrantfile 示例:

require 'yaml'

settings = YAML.load_file "vagrant_config.yml"

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  settings.each do |name, cfg|
    config.vm.define name do |agent|
      agent.vm.box = name
      cfg[:forwards].each do |port|
        agent.vm.network "forwarded_port", guest: port['guest'], host: port['host']
      end
      if cfg.has_key?(:shares)
        cfg[:shares].each do |sname, share|
          share[:host] = File.expand_path(share[:host])
          group = "vagrant"
          owner = "vagrant"
          host = share[:host]
          guest = share[:guest]
          if share.has_key?(:group)
            group = share[:group]
          end
          if share.has_key?(:owner)
            owner = share[:owner]
          end
          if
          box.vm.synced_folder host, guest, owner: owner, group: group
        end
      end
      agent.vm.provider :vmware_fusion do |v, override|
        v.box = name + "_fusion"
        v.box_url = cfg[:providers][:vmware_fusion]
        cfg[:properties].each do |prop, val|
          if prop == "cpus"
            prop = "numvcpus"
          elsif prop == "memory"
            prop = "memsize"
          end
          v.vmx[prop] = val
        end
        v.vmx['fixed-address'] = cfg['ip']
      end
      agent.vm.provider :virtualbox do |v, override|
        override.vm.box = name + "_vb"
        override.vm.box_url = cfg['providers']['virtualbox']
        override.vm.network :private_network, ip: cfg['ip']
        cfg[:properties].each do |prop, val|
          if prop == "numvcpus"
            prop = "cpus"
          elsif prop == "memsize"
            prop = "memory"
          end
          v.customize ["modifyvm", :id, "--#{prop}", "#{val}"]
        end
      end
      cfg[:provisions].each do |prov|
        agent.vm.provision prov[:provision] do |p|
          # setup keys that do not directly map
          if prov.has_key?('recipes')
            prov[:recipes].each do |r|
              p.add_recipe r
            end
            prov.delete(:recipes)
          end
          # setup 1:1 mapping keys
          prov.each do |key, val|
            if key != 'provision'
              p.instance_variable_set("@#{key}", val)
            end
          end
        end
      end
    end
  end
end

我通过设置一个 packer.io 构建并在那里添加配置来解决这个问题。
