流动的多机器配置

我正在尝试使用Ansible作为配置器在Vagrant中创建多机器环境.

我的Vagrantfile看起来像下一个:

   Vagrant.configure("2") do |config|

    config.vm.provision "ansible" do |ansible|
       ansible.limit = "all"
       ansible.playbook = "main.yml"
       ansible.inventory_path = "staging"
       ansible.verbose = "-vvvv"
     end

    config.vm.define "machine1" do |machine1| 
        machine1.vm.box = "ubuntu/trusty64"
        machine1.vm.network "private_network", ip:"192.168.77.10"
        machine1.vm.hostname = "machine1"
        machine1.vm.provider :virtualbox do |vb|
           vb.name = "machine1"
        end
    end    

    config.vm.define "machine2" do |machine2| 
        machine2.vm.box = "ubuntu/trusty64"
        machine2.vm.network "private_network", ip:"192.168.77.11"
        machine2.vm.hostname = "machine2"
        machine2.vm.provider :virtualbox do |vb|
            vb.name = "machine2"
        end
    end    

    config.vm.define "machine3" do |machine3| 
        machine3.vm.box = "ubuntu/trusty64"
        machine3.vm.network "private_network", ip:"192.168.77.12"
        machine3.vm.hostname = "machine3"
        machine3.vm.provider :virtualbox do |vb|
           vb.name = "machine3"
        end
    end      
end

库存:

[AppServers]
192.168.77.10
192.168.77.11
192.168.77.12

[WebServers]
192.168.77.11
192.168.77.12

[WebLoadBalancers]
192.168.77.10

[SlaveDbServers]
192.168.77.10
192.168.77.12

[MasterDbServers]
192.168.77.11

[DbLoadBalancers]
192.168.77.11

main.yml:

- hosts: all
  roles:
  - Common
  - ConsulServer
  - ConsulAgent  

- hosts: WebServers
  roles:
  - WebServer

- hosts: WebLoadBalancers
  roles:
  - LoadBalancer

- hosts: MasterDbServers
  roles:
  - DbServer

我想要3台机器.所有这些都必须包含常见的软件(Consul服务器和代理,vim等).还有一些 - 为每台机器拥有.但是,一旦我"vagrant up"只运行第一台机器,配置器运行,失败,因为其他2未创建.是否可以在创建所有机器后运行配置程序？或者我的方法不正确,我应该以其他方式执行此操作？感谢您的时间.

我遇到的第一个问题是ERROR: cannot find role in....我假设你有这些角色并为了简洁而排除它们.我的建议是在测试时有一个简单的Ansible剧本:

---
- hosts: all
  gather_facts: false
  tasks:
  - command: hostname -f

Vagrant.configure("2") do |config|
  N = 3

  VAGRANT_VM_PROVIDER = "virtualbox"
  ANSIBLE_RAW_SSH_ARGS = []

  (1..N-1).each do |machine_id|
    ANSIBLE_RAW_SSH_ARGS << "-o IdentityFile=.vagrant/machines/machine#{machine_id}/#{VAGRANT_VM_PROVIDER}/private_key"
  end

  (1..N).each do |machine_id|
    config.vm.define "machine#{machine_id}" do |machine|
      machine.vm.box = "ubuntu/trusty64"
      machine.vm.hostname = "machine#{machine_id}"
      machine.vm.network "private_network", ip: "192.168.77.#{10+machine_id-1}"

      # Only execute once the Ansible provisioner,
      # when all the machines are up and ready.
      if machine_id == N
        machine.vm.provision :ansible do |ansible|
          # Disable default limit to connect to all the machines
          ansible.limit = "all"
          ansible.playbook = "main.yml"
          ansible.inventory_path = "staging"
          ansible.verbose = "-v"
          ansible.raw_ssh_args = ANSIBLE_RAW_SSH_ARGS
        end
      end
    end
  end
end
