vagrant rsync-auto - Command-Line Interface
cli-rsyncauto
The "vagrant rsync-auto" command watches all local directories of any rsync configured synced folders and automatically initiates an rsync transfer when changes are detected.

rsync-auto

Command: vagrant rsync-auto

This command watches all local directories of any rsync synced folders and automatically initiates an rsync transfer when changes are detected. This command does not exit until an interrupt is received.

The change detection is optimized to use platform-specific APIs to listen for filesystem changes, and does not simply poll the directory.

Options

  • --[no-]poll - Force Vagrant to watch for changes using filesystem polling instead of filesystem events. This is required for some filesystems that do not support events. Warning: enabling this will make rsync-auto much slower. By default, polling is disabled.

Machine State Changes

The rsync-auto command does not currently handle machine state changes gracefully. For example, if you start the rsync-auto command, then halt the guest machine, then make changes to some files, then boot it back up, rsync-auto will not attempt to resync.

To ensure that the command works properly, you should start rsync-auto only when the machine is running, and shut it down before any machine state changes.

You can always force a resync with the rsync command.

Vagrantfile Changes

If you change or move your Vagrantfile, the rsync-auto command will have to be restarted. For example, if you add synced folders to the Vagrantfile, or move the directory that contains the Vagrantfile, the rsync-auto command will either not pick up the changes or may begin experiencing strange behavior.

Before making any such changes, it is recommended that you turn off rsync-auto, then restart it afterwards.
