Условная переадресация портов в файле vagrant

Question

Я пытаюсь создать настройку multi vm с использованием бродяг, где только перенаправленный порт сервера должен быть перенаправлен на указанный порт хост-машины. Не нужно открывать порты клиента. Но когда я пытаюсь сделать это с помощью прилагаемого Vagrantfile, он по какой-то причине оценивает мое условие для фильтрации клиентов, и для клиентов тоже. Может кто-нибудь указать, что я могу делать неправильно здесь?

Vagrantfile:

# -*- mode: ruby -*- 

# vi: set ft=ruby : 

VAGRANTFILE_API_VERSION = '2' 
BASEBOX = 'centos-6.7' 
BOX_MEMORY = '256' 

# Declare the cluster config in a hash 
HOST_CONFIG = { 
    'some_server' => '192.168.205.10', 
    'some_client' => '192.168.205.11' 
} 

# Create the vms 
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| 
    config.vm.box = BASEBOX 

    HOST_CONFIG.each do |hostname, hostip| 
    config.vm.network "forwarded_port", guest: 80, host: 8080 if hostname == "some_server" 
    config.vm.define hostname do |hname| 
     hname.vm.provider 'virtualbox' do |v| 
     v.name = hostname 
     v.customize [ 'modifyvm', :id, '--cpus', '1' ] 
     v.customize [ 'modifyvm', :id, '--memory', BOX_MEMORY ] 
     end 

     hname.vm.network 'private_network', ip: hostip 
     hname.vm.provision :hosts do |provisioner| 
     provisioner.autoconfigure = true 
     provisioner.sync_hosts = true 
     end 

     hname.vm.provision 'ansible' do |ansible| 
     ansible.playbook = 'bootstrap.yml' 
     end 
    end 
    end 
end 

Выход:

Vagrant cannot forward the specified ports on this VM, since they 
would collide with some other application that is already listening 
on these ports. The forwarded port to 8080 is already in use 
on the host machine. 

To fix this, modify your current project's Vagrantfile to use another 
port. Example, where '1234' would be replaced by a unique host port: 

    config.vm.network :forwarded_port, guest: 80, host: 1234 

Sometimes, Vagrant will attempt to auto-correct this for you. In this 
case, Vagrant was unable to. This is usually because the guest machine 
is in a state which doesn't allow modifying port forwarding.

Теперь вы эффективно установить значение vm.network для всех машин, если один из них назван some_server.

Вы должны поместить установку vm.network внутри vm.define -loop:

HOST_CONFIG.each do |hostname, hostip| 
    config.vm.define hostname do |hname| 
     hname.vm.network "forwarded_port", guest: 80, host: 8080 if hostname == "some_server" 
     hname.vm.provider 'virtualbox' do |v| 
     v.name = hostname 
     v.customize [ 'modifyvm', :id, '--cpus', '1' ] 
     v.customize [ 'modifyvm', :id, '--memory', BOX_MEMORY ] 
     end
