Vagrant Shell Provision 脚本运行两次

Question

我正在尝试从同一个 Vagrant Base Box 启动 3 个虚拟机。但是，仅创建了 2 个 VM。这是因为在配置第二个 VM 期间，shell 配置程序脚本执行了两次。结果，该过程终止，并出现下面详述的错误。

这是我的 Vagrantfile：

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

#The box name and the URL to Retrieve the Vagrant Box from
  config.vm.box = "eFx-Dev"
  config.vm.box_url = "http://web/provisioning/vagrant-boxes/centos7-basev0.1.box"
  config.ssh.insert_key = false


#Creating the first Dev Machine
#With network address being assigned via DHCP
#and bootstraped via a shell script.
#This script can be unique for each machine.
#But at the moment they are bootstarpped the same.
#The spects of the machine.
#Can be adjusted based on requirements.
  config.vm.define "eFxDev1" do |eFxDev1|
        eFxDev1.vm.hostname = "eFxDev1"
        eFxDev1.vm.box = "eFx-Dev"
        config.vm.network "public_network", type: "dhcp"
        config.vm.provision "shell", path: "vmscripts/bootstrap.sh"
        config.vm.provider "virtualbox" do |vb|
                vb.name = "eFx-Dev1"
                vb.memory = "10124"
                vb.customize ["modifyvm", :id, "--cpus", 4]
  end
end

  config.vm.define "eFxDev2" do |eFxDev2|
        eFxDev2.vm.hostname = "eFxDev2"
        eFxDev2.vm.box = "eFx-Dev"
        config.vm.network "public_network", type: "dhcp"
        config.vm.provision "shell", path: "vmscripts/bootstrap.sh"
        config.vm.provider "virtualbox" do |vb|
                vb.name = "eFx-Dev2"
                vb.memory = "10124"
                vb.customize ["modifyvm", :id, "--cpus", 4]
  end
end

  config.vm.define "eFxDev3" do |eFxDev3|
        eFxDev3.vm.hostname = "eFxDev3"
        eFxDev3.vm.box = "eFx-Dev"
        config.vm.network "public_network", type: "dhcp"
        config.vm.provision "shell", path: "vmscripts/bootstrap.sh"
        config.vm.provider "virtualbox" do |vb|
                vb.name = "eFx-Dev3"
                vb.memory = "10124"
                vb.customize ["modifyvm", :id, "--cpus", 4]
  end
 end
end

第一个 VM 是通过运行一次供应器外壳来部署的。VM 启动，Vagrant 继续创建第二个 VM：

==> eFxDev1: Importing base box 'eFx-Dev'...
==> eFxDev1: Matching MAC address for NAT networking...
...
==> eFxDev1: Running provisioner: shell...
    eFxDev1: Running: /tmp/vagrant-shell20170201-60595-wpa6qn.sh
==> eFxDev1: + yum install dos2unix -y --disableplugin=fastestmirror
==> eFxDev1: + sudo groupadd Efx
==> eFxDev1: groupadd: group 'Efx' already exists
...

第二个 VM 已部署，但由于某种原因运行配置程序脚本两次并失败：

==> eFxDev2: Importing base box 'eFx-Dev'...
==> eFxDev2: Matching MAC address for NAT networking...
...
==> eFxDev2: Running provisioner: shell...
    eFxDev2: Running: /tmp/vagrant-shell20170201-60595-1fwit5t.sh
==> eFxDev2: + yum install dos2unix -y --disableplugin=fastestmirror
==> eFxDev2: + sudo groupadd Efx
==> eFxDev2: groupadd: group 'Efx' already exists
...
==> eFxDev2: Running provisioner: shell...
    eFxDev2: Running: /tmp/vagrant-shell20170201-60595-1mu7y6h.sh
==> eFxDev2: + yum install dos2unix -y --disableplugin=fastestmirror
==> eFxDev2: Nothing to do
==> eFxDev2: + sudo groupadd Efx
==> eFxDev2: groupadd: group 'Efx' already exists
The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what

因此，该过程失败，第三个 VM 未配置。为什么供应脚本运行两次？

Answer 1

这是因为您正在混合config和特定的机器变量。

应用于的任何方法都config.vm将适用于您的所有机器（即使您将其放在特定的机器块中），因此最好将所有config.vm属性放在任何特定的机器块之外，您可以将脚本重写为

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

#The box name and the URL to Retrieve the Vagrant Box from
config.vm.box = "eFx-Dev"
config.vm.box_url = "http://web/provisioning/vagrant-boxes/centos7-basev0.1.box"
config.ssh.insert_key = false
config.vm.network "public_network", type: "dhcp"


#Creating the first Dev Machine
#With network address being assigned via DHCP
#and bootstraped via a shell script.
#This script can be unique for each machine.
#But at the moment they are bootstarpped the same.
#The spects of the machine.
#Can be adjusted based on requirements.
config.vm.define "eFxDev1" do |eFxDev1|
  eFxDev1.vm.hostname = "eFxDev1"
  eFxDev1.vm.provision "shell", path: "vmscripts/bootstrap.sh"
  eFxDev1.vm.provider "virtualbox" do |vb|
          vb.name = "eFx-Dev1"
          vb.memory = "10124"
          vb.customize ["modifyvm", :id, "--cpus", 4]
  end
end

config.vm.define "eFxDev2" do |eFxDev2|
  eFxDev2.vm.hostname = "eFxDev2"
  eFxDev2.vm.box = "eFx-Dev"
  eFxDev2.vm.provision "shell", path: "vmscripts/bootstrap.sh"
  eFxDev2.vm.provider "virtualbox" do |vb|
          vb.name = "eFx-Dev2"
          vb.memory = "10124"
          vb.customize ["modifyvm", :id, "--cpus", 4]
  end
end

config.vm.define "eFxDev3" do |eFxDev3|
  eFxDev3.vm.hostname = "eFxDev3"
  eFxDev3.vm.box = "eFx-Dev"
  eFxDev3.vm.provision "shell", path: "vmscripts/bootstrap.sh"
  eFxDev3.vm.provider "virtualbox" do |vb|
          vb.name = "eFx-Dev3"
          vb.memory = "10124"
          vb.customize ["modifyvm", :id, "--cpus", 4]
  end
 end
end
