使用 "vagrant up" 启动 vagrant 机器后打印消息

Print message after booting vagrant machine with "vagrant up"

我需要在 vagrant up 命令完成时显示一条消息。

我试过定义一个函数:

def hello
    puts 'hello'
end

然后调用它和文件结尾:

hello 

但它总是在输出的开头处打印,而不是在结尾处打印。如何在最后打印消息?

试试 vagrant-triggers plugin:

$ vagrant plugin install vagrant-triggers

然后添加:

config.trigger.after :up do
  puts 'hello'
end

Vagrantfile

Vagrant 不需要插件来在末尾显示消息,只需在所有其他供应商之后添加一个 shell 供应商,然后随心所欲地回显。

config.vm.provision "ansible" do |ansible|
  # ... or other existing provisioners

config.vm.provision "shell", privileged: false, inline: <<-EOF
  echo "Vagrant Box provisioned!"
  echo "Local server address is http://#{$hostname}"
EOF

这样,vagrant up 应该以这样的结尾:

==> default: Running provisioner: shell...
    default: Running: inline script
==> default: Vagrant Box provisioned!
==> default: Local server address is http://vagrant.dev

添加 privileged: false(如 Vagrant Issue 1673 中所述)对于抑制 Ubuntu 的 stdin: is not a tty 错误是必要的。

开始学习后Ruby我找到了理想的解决方案:)

BEGIN 在程序 运行.

之前声明要调用的代码
#!/usr/bin/ruby
puts "This is main Ruby Program"
BEGIN {
    puts "Initializing Ruby Program"
}

它将产生这个:

Initializing Ruby Program
This is main Ruby Program

它在 Vagrantfile 中完美运行。

Vagrant 现在内置支持在 vagrant up 之后显示消息。只需将此添加到您的 Vagrantfile:

config.vm.post_up_message = "This is the start up message!"

然后在您的虚拟机启动后,您会看到这条绿色消息:

==> default: Machine 'default' has a post `vagrant up` message. This is a message
==> default: from the creator of the Vagrantfile, and not from Vagrant itself:
==> default:
==> default:     This is the start up message!

您还可以将 HEREDOC 样式变量与 config.vm.post_up_message 一起使用,如下所示:

$msg = <<MSG
------------------------------------------------------
Local Websphere, accessible at 127.0.0.1

URLS:
 - app under test  - http://localhost:8080/<app url>/
 - ibm console     - http://localhost:9060/ibm/console

------------------------------------------------------
MSG

...
...

Vagrant.configure("2") do |config|
  config.vm.post_up_message = $msg
end

这将导致输出如下:

==> default: Machine 'default' has a post `vagrant up` message. This is a message
==> default: from the creator of the Vagrantfile, and not from Vagrant itself:
==> default:
==> default: ------------------------------------------------------
==> default: Local Websphere, accessible at 127.0.0.1
==> default:
==> default: URLS:
==> default:  - app under test  - http://localhost:8080/<app url>/
==> default:  - ibm console     - http://localhost:9060/ibm/console
==> default:
==> default: ------------------------------------------------------

来自@slm 的 heredoc 解决方案非常可爱,但您也可以将 heredoc 放在 中 Ruby 这样:

config.vm.post_up_message = <<-HEREDOC
  This is line 1
  This is line 2
  THis is line 3
HEREDOC

实际上有几个稍微不同的 Ruby heredoc 样式:https://infinum.co/the-capsized-eight/multiline-strings-ruby-2-3-0-the-squiggly-heredoc
