Is it possible to restart a machine when provisioning a machine using Vagrant and pickup where the script left off?

bash vagrant vagrant-provision

I was reading a tutorial in bash where they said to restart the machine, there was no option to restart a service directly, it was a matter of restarting the machine, and then there were more commands after that that still needed to be run when provisioning.

So is there any way to restart a box amid provisioning and then pick up where you left off after that?

As far as I know you can't have a single script/set of commands that would carry on where it left off if it attempts to restart the OS, such as:

  config.vm.provision "shell", inline: <<-SHELL
    echo $(date) > ~/rebootexample
    reboot
    echo $(date) >> ~/rebootexample
  SHELL

In this example the second echo call would not be carried out.

You could split the script/commands up and use a plugin such as vagrant reload.

An example snippet of a Vagrantfile to highlight its possible use:

  # execute code before reload
  config.vm.provision "shell", inline: <<-SHELL
     echo $(date) > ~/rebootexample
  SHELL

  # trigger reload
  config.vm.provision :reload

  # execute code after reload
  config.vm.provision "shell", inline: <<-SHELL
     echo $(date) >> ~/rebootexample
  SHELL
