A Vagrant plugin to automate bindfs mount in the VM. This allow you to change owner, group and permissions on files and, for example, work around NFS share permissions issues.
Some Background: Why
People often recommend switching to vagrant's VMWare-fusion provider. This reportedly has better performance, but shares with symlinks won't work. You also have to buy both the plugin and VMware Fusion.
The final recommendation, at least on Linux/OSX hosts, is to use nfs.
However, an NFS mount has the same numeric permissions in the guest as in the host.
If you're on OSX, for instance, a folder owned by the default OSX user will appear to be owned by
501:20 in the guest.
This is where
vagrant-bindfs comes in!
- mount your share over NFS into a temporary location in the guest
- re-mount the share to the actual destination with
vagrant-bindfs, setting the correct permissions
map_gid NFS options can be used to set the identity used to read/write files on the host side.
Vagrant-bindfs is distributed as a Ruby gem.
You can install it as any other Vagrant plugin with
vagrant plugin install vagrant-bindfs.
config.bindfs.bind_folder to configure folders that will be binded on VM startup.
The format is:
config.bindfs.bind_folder "/path/to/source", "/path/to/destination", options
By default, all folders are binded after folders syncing between host and guest machines.
You can pass a special
:hook) option to the bind_folder method to choose when a folder should be binded.
Supported values are :
:provision, to bind a folder after provisioning occured.
Vagrant.configure("2") do |config| [...] # Your VM configuration ## Basic usage config.bindfs.bind_folder "source/dir", "mount/point" ## Advanced options config.bindfs.bind_folder "source/dir", "mount/point", perms: "u=rw:g=r:o=r", create_as_user: true ## Complete example for a NFS shared folder # Static IP is required to use NFS shared folder, # this is only required for Virtualbox provider config.vm.network "private_network", ip: "192.168.50.4" # Declare shared folder with Vagrant syntax config.vm.synced_folder "host/source/dir", "/vagrant-nfs", type: :nfs # Use vagrant-bindfs to re-mount folder config.bindfs.bind_folder "/vagrant-nfs", "guest/mount/point" ## Share the default `vagrant` folder via NFS with your own options config.vm.synced_folder ".", "/vagrant", type: :nfs config.bindfs.bind_folder "/vagrant", "/vagrant" # Bind a folder after provisioning config.bindfs.bind_folder "/vagrant-after-provision", "another/guest/mount/point", after: :provision end
bind_folder config accept any option you can pass to bindfs.
vagrant-bindfs is compatible with bindfs from version 1.9 to 1.13.0.
Check lib/vagrant-bindfs/command.rb for a complete list of supported options and default values.
Both long arguments and shorthand are supported. If you set both, shorthand will prevail. Long arguments can be written indifferently with underscore ('force_user') or dash ('force-user') and as strings (:'force-user') or symbols (:force_user).
You can overwrite default options via
See bindfs man page for details.
vagrant-bindfs detects installed version of bindfs, translate option names when needed and ignore an option if it is not supported. As we may have missed something, it will warn you when a binding command fail.
On Debian (this includes Ubuntu), SUSE and CentOS (5-6) guest systems, vagrant-bindfs will try to install bindfs automatically if it is not installed. On other system, you'll get warned.
If you find this plugin useful, we could use a few enhancements! In particular, capabilities files for installing vagrant-bindfs on systems other than Debian or SUSE would be useful. We could also use some specs…
How to Test Changes
If you've made changes to this plugin, you can easily test it locally in vagrant. From the root of the repo, do:
bundle exec vagrant up
This will spin up a default Debian VM and try to bindfs-mount some shares in it.
Feel free to modify the included
Vagrantfile to add additional test cases.
