To speed up volumne mounting between Docker and your Mac:
- Install vagrant-bindfs
vagrant plugin install vagrant-bindfs
- Update your Vagrantfile:
config.vm.synced_folder "/Path/On/Mac", "/vagrant-nfs", type: :nfs
# Use vagrant-bindfs to re-mount folder
config.bindfs.bind_folder "/vagrant-nfs", "/Path/In/VM"
At time of writing, this solution is still faster than using Docker For Mac.
