OL 9 Packer Template for MAAS

Introduction

The Packer template in this directory creates an OL 9 AMD64 image for use with MAAS.

Prerequisites (to create the image)

  • A machine running Ubuntu 22.04+ with the ability to run KVM virtual machines.
  • qemu-utils, libnbd-bin, nbdkit and fuse2fs
  • Packer, v1.8.0 or newer

Requirements (to deploy the image)

Customizing the Image

The deployment image may be customized by modifying http/ol9.ks. See the OL9 kickstart documentation for more information.

Building the image using a proxy

The Packer template downloads the OL net installer from the Internet. To tell Packer to use a proxy set the HTTP_PROXY environment variable to your proxy server. Alternatively you may redefine iso_url to a local file, set iso_checksum_type to none to disable checksuming, and remove iso_checksum_url.

To use a proxy during the installation define the KS_PROXY variable in the environment, as bellow:

export KS_PROXY=$HTTP_PROXY

Building an image

You can easily build the image using the Makefile:

make

Alternatively you can manually run packer. Your current working directory must be in packer-maas/ol9, where this file is located. Once in packer-maas/ol9 you can generate an image with:

packer init .
PACKER_LOG=1 packer build .

Note: ol9.pkr.hcl is configured to run Packer in headless mode. Only Packer output will be seen. If you wish to see the installation output connect to the VNC port given in the Packer output or change the value of headless to false in ol9.pkr.hcl.

Installation is non-interactive.

Makefile Parameters

TIMEOUT

The timeout to apply when building the image. The default value is set to 1h.

Uploading an image to MAAS

    architecture='amd64/generic' filetype='tgz' \
