Xenial64 images

Simple Base images for a true minimal Ubuntu 16.04 64Bits (version: 0.1.1)

This is the source files for:

• iknite/xenial64 in atlas in both libvirt and virtualbox (for now)
• iknite/xenial64 in docker hub

Rationale

All the base images that I found always comes with something more than just the barebones.

This one didn't. It does not contain man pages, build-essential meta packages and nothing else than openssh-server.

Also make the common dpkg tweaks found in docker like faster installs, auto cache clean after installs and keep the index of the downloads.

Requirements

• packer-io
• debootstrap

Usage

• make to run both builders (debootstrap+ssh & packer).
• make vagrant to locally install the boxes.
• make docker to locally install the container.

Manual Usage

Docker

There's no other way to launch it than sudo src/mkimage-docker.sh

Packer

Before run the command please make sure no VT-x consumer are in the build machine. Otherwise virtualbox tries to trick you to kernel disable it.

Running packer build -parallel=false src/packer.json will succesfuly build.

Optional variables and their defaults:

  iso_checksum      = 23e97cd5d4145d4105fbf29878534049
  iso_checksum_type = md5
  iso_url           = http://releases.ubuntu.com/16.04/ubuntu-16.04-server-amd64.iso
  ssh_password      = vagrant
  ssh_username      = vagrant
  vm_name           = xenial64

Builders:

qemu
virtualbox-iso

Provisioners:

• file: Copies src/provision/apt.conf.d to /tmp
• shell: update.sh moves /tmp/docker-* to /etc/apt/apt.conf-d/, dist-upgrade the machine and reboot
• shell: install-vagrant.sh ensures vagrant can run in this machine
• shell: install-virtualbox.sh installs the basics for virtualbox.
