vagrant - 是否可以在 vagrant halt/suspend 之前添加 Action Hook

Question

我想在挂起或停止操作生效之前触发我的 VM 上的操作。

我看到可以使用的操作 Hook ，但它们都是在操作完成后才使用的https://www.vagrantup.com/docs/plugins/action-hooks.html .有什么线索吗？

我相信这些钩子(Hook)中的大部分都是用于插件开发的——你正在看的是 vagrant trigger plugin所以如果你想在暂停或停止之前完成操作:

Vagrant.configure("2") do |config|
  # Your existing Vagrant configuration
  ...

  # run some script before the guest is halted
  config.trigger.before :halt do
    info "Dumping the database before destroying the VM..."
    run_remote  "bash /vagrant/cleanup.sh"
  end

  # run some script before the guest is suspended
  config.trigger.before :suspend do
    info "Dumping the database before destroying the VM..."
    run_remote  "bash /vagrant/cleanup.sh"
  end

  # clean up files on the host after the guest is destroyed
  config.trigger.after :destroy do
    run "rm -Rf tmp/*"
  end

  # start apache on the guest after the guest starts
  config.trigger.after :up do
    run_remote "service apache2 start"
  end

end
