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.
--[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-automuch slower. By default, polling is disabled.
» Machine State Changes
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
rsync-auto will not attempt to resync.
To ensure that the command works properly, you should start
only when the machine is running, and shut it down before any machine
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
command will either not pick up the changes or may begin experiencing
Before making any such changes, it is recommended that you turn off
rsync-auto, then restart it afterwards.
