Usage

Install Packer (1.7+), Vagrant (2.2.16+) and VirtualBox (6.1+).

If you are on a Debian/Ubuntu host, you should also install and configure the NFS server. E.g.:

# install the nfs server.
sudo apt-get install -y nfs-kernel-server

# enable password-less configuration of the nfs server exports.
sudo bash -c 'cat >/etc/sudoers.d/vagrant-synced-folders' <<'EOF'
Cmnd_Alias VAGRANT_EXPORTS_CHOWN = /bin/chown 0\:0 /tmp/*
Cmnd_Alias VAGRANT_EXPORTS_MV = /bin/mv -f /tmp/* /etc/exports
Cmnd_Alias VAGRANT_NFSD_CHECK = /etc/init.d/nfs-kernel-server status
Cmnd_Alias VAGRANT_NFSD_START = /etc/init.d/nfs-kernel-server start
Cmnd_Alias VAGRANT_NFSD_APPLY = /usr/sbin/exportfs -ar
%sudo ALL=(root) NOPASSWD: VAGRANT_EXPORTS_CHOWN, VAGRANT_EXPORTS_MV, VAGRANT_NFSD_CHECK, VAGRANT_NFSD_START, VAGRANT_NFSD_APPLY
EOF

For more information see the Vagrant NFS documentation.
