Action Hooks

Action hooks provide ways to interact with Vagrant at a very low level by injecting middleware in various phases of Vagrant's lifecycle. This is an advanced option, even for plugin development.

~> Warning: Advanced Topic! Developing plugins is an advanced topic that only experienced Vagrant users who are reasonably comfortable with Ruby should approach.

Public Action Hooks

The following action hooks are available in the core of Vagrant. Please note that this list is not exhaustive and additional hooks can be added via plugins.

• environment_plugins_loaded - called after the plugins have been loaded, but before the configurations, provisioners, providers, etc. are loaded.

• environment_load - called after the environment and all configurations are fully loaded.

• environment_unload - called after the environment is done being used. The environment should not be used in this hook.

• machine_action_boot - called after the hypervisor has reported the machine was booted.

• machine_action_config_validate - called after all Vagrantfiles have been loaded, merged, and validated.

• machine_action_destroy - called after the hypervisor has reported the virtual machine is down.

• machine_action_halt - called after the hypervisor has moved the machine into a halted state (usually "stopped" but not "terminated").

• machine_action_package - called after Vagrant has successfully packaged a new box.

• machine_action_provision - called after all provisioners have executed.

• machine_action_read_state - called after Vagrant has loaded state from disk and the hypervisor.

• machine_action_reload - called after a virtual machine is reloaded (varies by hypervisor).

• machine_action_resume - called after a virtual machine is moved from the halted to up state.

• machine_action_run_command - called after a command is executed on the machine.

• machine_action_ssh - called after an SSH connection has been established.

• machine_action_ssh_run - called after an SSH command is executed.

• machine_action_start - called after the machine has been started.

• machine_action_suspend - called after the machine has been suspended.

• machine_action_sync_folders - called after synced folders have been set up.

• machine_action_up - called after the machine has entered the up state.

Private API

You may find additional action hooks if you browse the Vagrant source code, but only the list of action hooks here are guaranteed to persist between Vagrant releases. Please do not rely on the internal API as it is subject to change without notice.
