Vagrant : reusing a puppet_server block for multiple VMs

Question

我有一个 Vagrantfile，其中定义了两个虚拟机。我想使用 puppet 大师来配置那些。当我只有一个虚拟机时，我可以使用

config.vm.provision "puppet_server" do |puppet|
 puppet.puppet_server           = "puppet.srv"
 puppet.puppet_node             =  config.vm.hostname
 puppet.client_cert_path        = "../puppet/ssl/ca/signed/#{config.vm.hostname}.pem"
 puppet.client_private_key_path = "#{config.vm.hostname}.key"
 puppet.options                 = "--test"
end

我想为两个虚拟机重用此 block ，但不能，因为每个虚拟机的 client_cert_path 和 client_private_key_path 需要不同。

当我尝试使用这些设置执行 Vagrantfile 时，我得到

There are errors in the configuration of this machine. Please fix the following errors and try again:

puppet server provisioner:

• The specified client cert path could not be found
• The specified client private key path could not be found
• "puppet_node" is required when a client cert or key is specified

这让我相信 config.vm.hostname 未定义

如何在不重复代码块的情况下实现此目的？

Answer 1

我在 Vagrant.configure block 之后添加了一个 Helper 类:

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
# regular configuration here
end

class Helper
  def self.provision_puppet(vm)
    vm.provision "puppet_server" do |puppet|
      puppet.puppet_server            = "puppet.test"
      puppet.puppet_node              =  vm.hostname
      puppet.client_cert_path         = "../puppet/ssl/ca/signed/#{vm.hostname}.pem"
      puppet.client_private_key_path  = "ssl/#{vm.hostname}.key"
      puppet.options                  = "--test"
    end
  end
end

然后为每个虚拟机调用Helper.provision_vm

config.vm.define "vpn", autostart: false do |vpn|
  # various configurations
  Helper.provision_puppet vpn.vm
end
