SMB

Synced folder type: smb

Vagrant can use SMB as a mechanism to create a bi-directional synced folder between the host machine and the Vagrant machine.

SMB is built-in to Windows machines and provides a higher performance alternative to some other mechanisms such as VirtualBox shared folders.

Prerequisites

To use the SMB synced folder type,the machine running Vagrant must be a Windows machine. In addition to this,the command prompt executing Vagrant must have administrative privileges. Vagrant requires these privileges in order to create new network folder shares.

The destination machine must be able to mount SMB filesystems. On Linux the package to do this is usually called smbfs or cifs. Vagrant knows how to automatically install this for some operating systems.

Options

The SMB synced folder type has a variety of options it accepts:

• smb_host(string) - The host IP where the SMB mount is located. If this isn't specified,Vagrant will attempt to determine this automatically.

• smb_password(string) - The password used for authentication to mount the SMB mount. This is the password for the username specified by smb_username. If this is not specified,Vagrant will prompt you for it. It is highly recommended that you do not set this,since it would expose your password directly in your Vagrantfile.

• smb_username(string) - The username used for authentication to mount the SMB mount. This is the username to access the mount,not the username of the account where the folder is being mounted to. This is usually your Windows username. If this isn't specified,Vagrant will prompt you for it.

Example

The following is an example of using SMB to sync a folder:

Vagrant.configure("2") do |config|
  config.vm.synced_folder ".","/vagrant",type: "smb"
end

Limitations

Because SMB is a relatively new synced folder type in Vagrant,it still has some rough edges. Hopefully,future versions of Vagrant will address these.

The primary limitation of SMB synced folders at the moment is that they are never pruned or cleaned up. Once the folder share is defined,Vagrant never removes it. To clean up SMB synced folder shares,periodically run net share in a command prompt,find the shares you don't want,then run net share? NAME /delete for each,where NAME is the name of the share.
