不使用打包在盒子中的 Vagrantfile(通过打包器)

Question

我用了packer创建一个 vagrant我正在运行和包装的车间的盒子 vagrantfile通过 Vagrant 后处理器中的 vagrantfile_template 指令在框中输入，如下所示:

...
"post-processors": [{
  "type": "vagrant",
  "vagrantfile_template": "vagrantfile_templates/workshop",
  "compression_level": "{{user `compression_level`}}",
  "output": "fedora-22-x86_64.box"
}],
...

生成的 .box 的内容是:

% tar -tf workshop.box
Vagrantfile
box.ovf
metadata.json
packer-fedora-22-x86_64-disk1.vmdk

框中Vagrantfile 的内容似乎没问题，并且包含打包程序配置中指定的vagrantfile_template 的内容。请注意，此 Vagrantfile 定义了两个名为 client 和 server 的 VM:

% tar -O -xf freeipa-workshop.box Vagrantfile

# The contents below were provided by the Packer Vagrant post-processor

Vagrant.configure("2") do |config|
  config.vm.base_mac = "0800278AF3E8"
end


# The contents below (if any) are custom contents provided by the
# Packer template during image build.
# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|

  config.vm.box = "workshop"
  config.vm.synced_folder ".", "/vagrant", disabled: true

  config.vm.define "server" do |server|
    server.vm.network "private_network", ip: "192.168.33.10"
    server.vm.hostname = "server.ipademo.local"
  end

  config.vm.define "client" do |client|
    client.vm.network "private_network", ip: "192.168.33.20"
    client.vm.hostname = "client.ipademo.local"
  end

end

我将盒子添加到名为 workshop 的 vagrant 中:

% vagrant box add --name workshop workshop.box 
==> box: Adding box 'workshop' (v0) for provider: 
    box: Downloading: file:///.../workshop.box
==> box: Successfully added box 'workshop' (v0) for 'virtualbox'!
% vagrant box list
workshop                  (virtualbox, 0)

问题描述

当我执行 vagrant init workshop 然后执行 vagrant up 时，框中包含的 Vagrantfile 未应用:

% vagrant init workshop
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.
% cat Vagrantfile 
# -*- mode: ruby -*-
# vi: set ft=ruby :

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.
Vagrant.configure(2) do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at
  # https://docs.vagrantup.com.

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://atlas.hashicorp.com/search.
  config.vm.box = "workshop"

  ... and so on (the rest of the default Vagrantfile)

% vagrant up --provider virtualbox
Bringing machine 'default' up with 'virtualbox' provider...
...

哇哦!为什么会出现 default？ According to the Vagrantfile docs应使用随盒子打包的 Vagrantfile，并且应将当前目录中的其他 Vagrantfile 合并到其中。但事实并非如此。

Vagrant 1.7.2 是正在使用的版本。

我希望研讨会参与者能够启动包装盒中包含的 Vagrantfile 中定义的 VM，而无需带外提供 Vagrantfile(以便最小化依赖)。我错过了什么重要的事情吗？

Answer 1

众所周知，Vagrant 以预先确定的顺序加载和合并多个 Vagrantfiles here (在同一部分中，他们还指出多个 Vagrant.configure block 也是可以的)。

当 Vagrant 无法获取使用 vagrantfile_template 捆绑在 .box 中的 config.vm.communicator = "winrm" 配置时，我遇到了同样的问题>。

但是，通过使用 vagrant --debug，我注意到 Vagrant 似乎已经缓存了来自同一盒子的先前构建的捆绑 Vagrantfile:

INFO loader: Set :"26224240_win7sp1_x64_virtualbox" = ["#<Pathname:/home/thomas/.vagrant.d/boxes/win7sp1_x64/0/virtualbox/Vagrantfile>"]

有人会认为 vagrant destroy 会删除 vagrant.d 中的关联文件，但事实并非如此，所以我能够通过手动删除 来解决问题>~/.vagrant.d/boxes/win7sp1_x64.

我通过查看确实在使用 WinRM 确认它现在正在按预期工作:

==> default: Waiting for machine to boot. This may take a few minutes...
    default: WinRM address: 127.0.0.1:55985
    default: WinRM username: vagrant
    default: WinRM execution_time_limit: PT2H
    default: WinRM transport: negotiate
==> default: Machine booted and ready!

即使初始化目录下的Vagrantfile没有那个配置:

Vagrant.configure("2") do |config|
    config.vm.box = "win7sp1_x64"
    config.vm.box_url = "/media/data/VagrantBaseBoxes/win7sp1_x64/win7sp1_x64-virtualbox.box"
end

长话短说:

确保 vagrant.d 中不存在可能会覆盖 'packer-ed 框中配置的“旧”Vagrantfile(请参阅“加载顺序和合并”在上面的链接中)。
