Can I modify the ownership for a shared folder in vagrant?

问题

I use vagrant and chef to develop my own blog in a virtual machine. To have easy access to the wordpress folder I created a shared folder.

Basically the wordpress folder is on my host and gets mounted as shared folder in /var/www/wordpress in the VM. The configuration is similar to:

config.vm.share_folder "foo", "/guest/path", "/host/path"

My problem is that the ownership in my VM is always vagrant:vagrant even if I change it on my host. Ownership changes in the VM get ignored.

I cannot use chown to set the ownership of the upload directory to www-data:www-data.

It is possible to use chmod and change the access restrictions to 777, but this is a really ugly hack.

Here is what I actually want. Is this possible?:

Development: Access to the shared folder from my host.
Access Restriction: On the VM all files and folders should have proper and secure ownership and access restrictions.

As @StephenKing suggests you can change the options of the whole directory.

The relevant function is not documented but the source tells us:

# File 'lib/vagrant/config/vm.rb', line 53

def share_folder(name, guestpath, hostpath, opts=nil)
  @shared_folders[name] = {
    :guestpath => guestpath.to_s,
    :hostpath => hostpath.to_s,
    :create => false,
    :owner => nil,
    :group => nil,
    :nfs   => false,
    :transient => false,
    :extra => nil
  }.merge(opts || {})
end

Basically you can set group, owner and acl for the whole folder which is way better than setting everything to world writable on the host. I have not found any method to change the ownership of a nested directory.

Here is a quickfix:

config.vm.share_folder "v-wordpress", "/var/www/wordpress", "/host/path", :owner => "www-data", :group => "www-data"

in 1.2+

config.vm.synced_folder "src/", "/srv/website",
  owner: "root", group: "root"

You can allow changing the ownership inside the guest:

config.vm.share_folder "foo", "/guest/path", "/host/path", {:extra => 'dmode=777,fmode=777'}

Following up on @StephenKing and @aycokoster awesome tips, I had a use-case for mounting another directory read-only.

I added

config.vm.share_folder "foo", "/guest/path", "/host/path", :extra => 'ro'

and

# discard exit status because chown `id -u vagrant`:`id -g vagrant` /host/path is okay

vagrant up || true

As the other answers have pointed out you should probably set the correct owner and group using the owner and group configuration options.

However, sometimes that won't work (for example when the target user is only created later on during provision). In these cases, you can remount the share:

sudo mount -t vboxsf -o uid=`id -u www-data`,gid=`id -g www-data` /path/to/share /path/to/share
