Requirements

Virtual Box and Vagrant needs to be installed and configured first!

I am gonna be using the Ubuntu base image “Ubuntu 18.04, Bionic Beaver”

Create a new folder were you can store your OS image and Vagrant file.

mkdir VagrantUbuntuBox
cd VagrantUbuntuBox

Download the iso

curl http://archive.ubuntu.com/ubuntu/dists/bionic/main/installer-amd64/current/images/netboot/mini.iso -o Ubuntu-mini.iso

Virtual Box

Create a new vm

VM Settings

Disable audio and USB.

Set network to NAT and add port forwarding for SSH.

Select your iso image.

Start the vm and confirm the default settings during the installation.

user = vagrant

pw = vagrant

Use entire disk

Install automatic updates

Don’t forget to remove the iso, after finishing the installation.

Now you should be able to log in with user vagrant

Although vagrant is a superuser you don’t want to type sudo < command > all the time.

To prevent that:

sudo su -
visudo -f /etc/sudoers.d/vagrant

and add

vagrant ALL=(ALL) NOPASSWD:ALL

Adding insecure Keypair from https://raw.githubusercontent.com/hashicorp/vagrant/master/keys/vagrant.pub

mkdir /home/vagrant/.ssh
chmod 0700 /home/vagrant/.ssh
cd /home/vagrant/.ssh
wget https://raw.githubusercontent.com/hashicorp/vagrant/master/keys/vagrant.pub
mv vagrant.pub authorized_keys
chmod 0600 authorized_keys
cd ../
chown -R vagrant .ssh/

SSH CONFIG

open

vi /etc/ssh/sshd_config

and add to the end of the file

AuthorizedKeysFile %h/.ssh/authorized_keys

Restart the ssh service

service ssh restart

Install the following additional packages

apt-get install -y gcc build-essential git linux-headers-$(uname -r) dkms

Install Virtual Box Guest Additions

Insert Guest Additions CD image from Devices menu

mount /dev/cdrom /mnt
cd /mount
./VBoxLinuxAdditions.run

Zero out the disk to fix fragmentation issues and to compress the disk easier

dd if=/dev/zero of=/EMPTY bs=1M
rm -f /EMPTY

Create your box

Run

vagrant init ubuntu64 -m
vagrant up

You now should be able to access your box via ssh

vagrant ssh
