提供多个虚拟机与他们自己的木偶环境

Question

我试图从一个单一的Vagrantfile提供两个虚拟机。我的目标是能够启动Web服务器和数据库服务器，应用一些常用配置，然后根据系统是否托管数据或网站来应用更具体的配置。很明显，如果我在做两个静态虚拟机，这不是问题，但最终系统数量可能是动态的，所以我想首先解决这个问题。下面是Vagrantfile的要点：

Vagrant.config(2) do |config| 
    config.vm.provision :shell, inline: 'apt-get install -y -q puppet' 
    config.vm.box = 'ubuntu/xenial64' 

    config.vm.provision :puppet do |default_puppet| 
     puppet.manifests_path = 'puppet/manifests' 
     puppet.module_path = 'puppet/modules' 
    end 

    config.vm.define 'web' do |web| 
     config.vm.provision :puppet do |web_puppet| 
      web_puppet.environment_path = 'puppet/environments' 
      web_puppet.environment = 'web' 
     end 
    end 

    config.vm.define 'db' do |db| 
     config.vm.provision :puppet do |db_puppet| 
      db_puppet.environment_path = 'puppet/environments' 
      db_puppet.environment = 'db' 
     end 
    end 
end 

我有以下目录结构：

. 
├── Vagrantfile 
└── puppet 
   ├── environments 
   │   ├── db 
   │   │   └── manifests 
   │   │    └── default.pp 
   │   └── web 
   │    └── manifests 
   │     └── default.pp 
   ├── hiera.yaml 
   ├── manifests 
   │   └── default.pp 
   └── modules 
    ├── ntp 
    └── stdlib 

我manifests/default.pp很简单：

# Set up some default stuff that both servers should have 
class { '::ntp': 
    servers => [ 
     '0.ubuntu.pool.ntp.org', 
     '1.ubuntu.pool.ntp.org', 
     '2.ubuntu.pool.ntp.org', 
     '3.ubuntu.pool.ntp.org', 
    ] 
} 

file { '/home/ubuntu/file0.txt': 
    ensure => file, 
    content => 'should be available on all systems' 
} 

而且/environments/{db,web}/manifests/default.pp文件也相当简单，基本上就是这样：

# set up something specifically for the database server 
file { '/home/ubuntu/file1.txt': 
    ensure => file, 
    content => 'this file should only be on the db server.' 
} 

文件名和内容已更改，因此在查看一切正常工作的目录时，这一点显而易见。

这几乎可以工作 - 当我更新manifests/default.pp时，更改将应用​​于两者;当我更新environments/web/manifests/default.ppweb服务器获取这些更改。但是，当我准备了db环境，它得到两种环境：

==> web: Running provisioner: puppet... 
==> web: Running Puppet with default.pp... 
==> web: Info: Loading facts 
==> web: Notice: Compiled catalog for web.vm in environment production in 0.64 seconds 
==> web: Info: Applying configuration version '1481059856' 
==> web: Notice: /Stage[main]/Main/File[/home/ubuntu/file0.txt]/ensure: defined content as '{md5}ba94d90e4b2e228b54c75d9110e3179c' 
==> web: Notice: Finished catalog run in 0.07 seconds 
==> web: Running provisioner: puppet... 
==> web: Running Puppet with environment web... 
==> web: Notice: Compiled catalog for web.vm in environment web in 0.12 seconds 
==> web: Notice: Finished catalog run in 0.01 seconds 

==> db: Running provisioner: puppet... 
==> db: Running Puppet with default.pp... 
==> db: Info: Loading facts 
==> db: Notice: Compiled catalog for db.vm in environment production in 0.64 seconds 
==> db: Info: Applying configuration version '1481059866' 
==> db: Notice: /Stage[main]/Main/File[/home/ubuntu/file0.txt]/ensure: defined content as '{md5}ba94d90e4b2e228b54c75d9110e3179c' 
==> db: Notice: Finished catalog run in 0.07 seconds 

** shouldn't be doing this ** 
==> db: Running provisioner: puppet... 
==> db: Running Puppet with environment web... 
==> db: Notice: Compiled catalog for db.vm in environment web in 0.11 seconds 
==> db: Notice: Finished catalog run in 0.01 seconds 

** this is fine though ** 
==> db: Running provisioner: puppet... 
==> db: Running Puppet with environment db... 
==> db: Notice: Compiled catalog for db.vm in environment db in 0.12 seconds 
==> db: Notice: Finished catalog run in 0.01 seconds 

这发生在我运行vagrant provision。现在，我还发现，如果我运行vagrant provision db，则只应用db环境......但我不应该能够在多台机器上设置每台计算机的环境吗？有没有另一种方法来做我想做的事情？

然后我意识到我在同一个config命名空间中为两个定义的机器工作。这是我的调整Vagrantfile：

Vagrant.config(2) do |config| 
    config.vm.provision :shell, inline: 'apt-get install -y -q puppet' 
    config.vm.box = 'ubuntu/xenial64' 

    config.vm.provision :puppet do |default_puppet| 
     puppet.manifests_path = 'puppet/manifests' 
     puppet.module_path = 'puppet/modules' 
    end 

    config.vm.define 'web' do |web| 
     # now it's web.vm.provision, not config.vm.provision 
     web.vm.provision :puppet do |web_puppet| 
      web_puppet.environment_path = 'puppet/environments' 
      web_puppet.environment = 'web' 
     end 
    end 

    config.vm.define 'db' do |db| 
     # now it's db.vm.provision, not config.vm.provision 
     db.vm.provision :puppet do |db_puppet| 
      db_puppet.environment_path = 'puppet/environments' 
      db_puppet.environment = 'db' 
     end 
    end 
end
