Trigger to execute on guest and create a database dump before vagrant destroy

[micheldenegri]

Hello, Im curious if i can use your plugin to execute a script that connects to guest machine and create a database dump before vagrant destroy. or is it possible to use those triggers to execute the script directly on the guest machine?

Hey,

Despite the plugin is intended for running script on the host, it could perhaps be used in a quite hacky way to get what you need:

config.trigger.before :destroy do
  info "Dumping the database before destroying the VM..."
  run  "vagrant ssh -c 'your dump command'"
end

Note that:

1. I've used the new syntax introduced today with version 0.3 of the plugin (here some details).
2. Altough I don't see why it shouldn't work, I've never tested a similar scenario.
3. Obviously your dump destination must be a shared folder, it would otherwise be destroyed.

Thanks a lot @emyl it works

For anyone finding this, you can also now use 'run_remote':

config.trigger.before :destroy do
  info "Dumping the database before destroying the VM..."
  run_remote  "command"
end

If you prefer to use a shell script to contain all your teardown/cleanup tasks:

config.trigger.before :destroy do
  info "Dumping the database before destroying the VM..."
  run_remote  "bash /vagrant/cleanup.sh"
end

... where /vagrant/cleanup.sh is a script that will exist on both the host and the guest, because vagrant shares the directory containing the vagrantfile on the host, with /vagrant on the guest by default.

I see its a bit old but really useful, the run_remote command should be highlighted from the main documentation.
