Introduction

We create a Vagrant box for Ubuntu 16.04 LTS, based on the official Ubuntu cloud image. Currently our base box is the same as the cloud image, but

Disk size is increased to 40GB from 10GB.
GuestAdditions updated to version 5.1.18
Basic users and passwords set
Minimal puppet client installed

Get base box and add as vagrant box to the system

vagrant@zg-2: vagrant box add https://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-vagrant.box --name=xenial-server-cloudimg-amd64-vagrant

Create a new virtual machine based on the base box and start it

vagrant@zg-2:~/vms$ mkdir xenial-base
vagrant@zg-2:~/vms$ cd xenial-base
vagrant@zg-2:~/vms/xenial-base$ vi Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.box = "xenial-server-cloudimg-amd64-vagrant"
  config.vm.hostname = "xenial-base.softxs.ch"
  config.vm.provider :virtualbox do |v|
    v.customize ["modifyvm", :id, "--name",   "xenial-base"]
    v.customize ["modifyvm", :id, "--memory", "8192"]
  end
  config.vm.network :private_network, ip: "172.16.1.100", netmask: "255.240.0.0"
end
vagrant@zg-2:~/vms/xenial-base$ vagrant up

Updating VirtualBox Guest Additions

vagrant@zg-2:~/vms/xenial-base$ vagrant ssh
ubuntu@xenial-base:~$ sudo su -
root@xenial-base:~# cd /tmp
root@xenial-base:~# wget http://download.virtualbox.org/virtualbox/5.1.18/VBoxGuestAdditions_5.1.18.iso
root@xenial-base:~# mount -o loop /tmp/VBoxGuestAdditions_5.1.18.iso /mnt
root@xenial-base:~# apt-get remove virtualbox-guest-utils
root@xenial-base:~# apt-get install make gcc perl linux-headers-$(uname -r)
root@xenial-base:~# /mnt/VBoxLinuxAdditions.run
root@xenial-base:~# umount /mnt
root@xenial-base:~# rm /tmp/VBoxGuestAdditions_5.1.18.iso

Set Users and Passords

Set root password and vagrant user

root@xenial-base:~# passwd
root@xenial-base:~# adduser vagrant
# add vagrant to all groups, where ubuntu is a member (with the exeption of the ubuntu group)
root@xenial-base:~# vi /etc/group
:%s/ubuntu$/ubuntu,vagrant/
:x
# add vagrant as sudoer without password
root@xenial-base:~# cat >> /etc/sudoers.d/90-cloud-init-users
vagrant ALL=(ALL) NOPASSWD:ALL
CTRL-D
# Set auth key for vagrant user (copied from user ubuntu)
root@xenial-base:~# mkdir ~vagrant/.ssh
root@xenial-base:~# cp ~ubuntu/.ssh/authorized_keys ~vagrant/.ssh
root@xenial-base:~# chown -R vagrant:vagrant ~vagrant/.ssh
root@xenial-base:~# chmod 755 ~vagrant/.ssh
root@xenial-base:~# chmod 600 ~vagrant/.ssh/authorized_keys
root@xenial-base:~# exit
ubuntu@xenial-base:~$ exit

Resize HDD

vagrant@zg-2:~/vms/xenial-base$ vagrant halt
vagrant@zg-2:~/VirtualBox VMs/xenial-base$ cd ~/VirtualBox\ VMs/xenial-base
vagrant@zg-2:~/VirtualBox VMs/xenial-base$ VBoxManage clonehd ubuntu-xenial-16.04-cloudimg.vmdk clone-disk1.vdi --format vdi
vagrant@zg-2:~/VirtualBox VMs/xenial-base$ VBoxManage showhdinfo clone-disk1.vdi
vagrant@zg-2:~/VirtualBox VMs/xenial-base$ VBoxManage modifyhd clone-disk1.vdi --resize 40960
vagrant@zg-2:~/VirtualBox VMs/xenial-base$ vboxmanage list hdds
vagrant@zg-2:~/VirtualBox VMs/xenial-base$ VBoxManage storageattach xenial-base --storagectl SCSI --medium none --type hdd --port 0
vagrant@zg-2:~/VirtualBox VMs/xenial-base$ vboxmanage closemedium disk ce7c94a3-7b50-4ab8-b7b1-74eb852dd094 --delete
vagrant@zg-2:~/VirtualBox VMs/xenial-base$ VBoxManage storageattach xenial-base --storagectl SCSI --medium clone-disk1.vdi --type hdd --port 0

Minimal puppet client setup

vagrant@xenial-rails:~$ sudo su -
root@xenial-rails:~# apt install puppet-common
root@xenial-rails:~# cd /etc/puppet
root@xenial-rails:~# rm -rf [efmt]*
root@xenial-rails:~# vi puppet.conf
[agent]
  server      = puppet
  report      = true

Repackaging the VM into a new Vagrant box

vagrant@zg-2:~/vms/xenial-base$ vagrant package --output ~/boxes/xenial-base.box
vagrant@zg-2:~/vms/xenial-base$ vagrant box add xenial-base ~/boxes/xenial-base.box
