Quick tip: Preventing `Vagrant Destroy`

I’m using Vagrant to test out some scripts, and I really need to stop myself from destroying my caching proxy that I’m running in the test.

To do that, I’ve got this Vagrantfile:

Vagrant.configure("2") do |config|
  config.vm.define "caching-proxy" do |this|
    this.trigger.before :destroy do |trigger|
      trigger.info = "This machine is currently prevented from being destroyed. Please remove the trigger to be able to destroy it.
      trigger.abort = 1
    end
    this.vm.box = "ubuntu/jammy64"
    # etc
  end
  config.vm.define "normalnode" do |this|
    this.vm.box = "ubuntu/jammy64"
  end
end

Now when I try to run vagrant destroy caching-proxy I get:

==> caching-proxy: Running action triggers before destroy ...
==> caching-proxy: Running trigger...
==> caching-proxy: This machine is currently prevented from being destroyed. Please remove the trigger to destroy it.
==> caching-proxy: Vagrant has been configured to abort. Terminating now...

Running vagrant destroy normalnode I get:

    normalnode: Are you sure you want to destroy the 'normalnode' VM? [y/N] y
==> normalnode: Forcing shutdown of VM...
==> normalnode: Destroying VM and associated drives...

Perfect.
