Building Vagrant box images

This document describes how to build vagrant box images for the FreeIPA workshop.

Requirements

Packer template

Apply the following changes to the fedora-28-x86_64.json packer template:

  • Add the scripts/fedora/ipa.sh provisioner and copy (or symlink) ipa.sh from this repository to scripts/fedora. This script installs the FreeIPA packages and creates other files required for the workshop.

Building the virtualbox image

Build the images:

$BIN_PACKER build -only=virtualbox-iso -var disk_size=4000 -var memory=1024 fedora-28-x86_64.json

Packer stores images and other data in /tmp during processing. If you have limited space in /tmp set TMPDIR to point somewhere else with more space.

Building the QEMU/libvirt image

Build the image:

$BIN_PACKER build -only=qemu -var disk_size=4000 -var memory=1024 fedora-28-x86_64.json

The output box is a gzip-compressed tarball. Unfortunately, the VM image it contains is not sparse and will waste a lot of space (and time) when Vagrant unpacks and imports the image. Therefore we unpack, sparsify and repack the box:

mkdir box && cd box && tar -xf ../fedora-28-x86_64-libvirt.box
virt-sparsify --in-place box.img
tar -czf ../fedora-28-x86_64-libvirt.box * && cd .. && rm -rf box

Uploading boxes to HashiCorp Atlas

Vagrant by default looks for boxes in a directory called Atlas. Therefore is is good to make images available there, so that people can easily download them as part of workshop preparation.

  1. Log into https://app.vagrantup.com/.
  2. Create or edit the freeipa-workshop box.
  3. Create a new version of the box (left-hand menu). Each version can include images for multiple providers.
  4. Create new provider for *virtualbox* and upload the corresponding .box file.
  5. Create new provider for *libvirt* and upload the corresponding .box file. libvirt may not appear as an autocomplete option but type it in anyway.
  6. Release the new version (this makes it available for Vagrant to download). Edit the version, then click Release version.
