Update `image-generation` doc

[zarcen]

Summary

image-generation.

In this PR #70, I see there are new image built with ubuntu 22.04 and newer k8s versions. However, the content still points out to a very stale branch in this repo: https://github.com/spectrocloud/cluster-api-provider-maas/blob/main/image-generation/Dockerfile#L10C29-L10C90

Is it possible to share what is the current packer configs to generate those ubuntu 22.04 images?

[0xAlcibiades]

Seconding this.

[JonnyBGod]

Any chance we could get an updated version of the image build process?

[vasartori]

The image generation is based in this repo: https://github.com/kubernetes-sigs/image-builder

Generate a qemu image

make build-qemu-ubuntu-2204

When the image is created, run this commands:

  TMP_DIR=$(mktemp -d /tmp/packer-maas-XXXX)
  echo 'Binding packer qcow2 image output to nbd ...'
  modprobe nbd
  qemu-nbd -d /dev/nbd4
  qemu-nbd -c /dev/nbd4 -n ./output/ubuntu-${OUTPUT_OS_VERSION}-kube-v${K8S_VERSION}/ubuntu-${OUTPUT_OS_VERSION}-kube-v${K8S_VERSION}
  echo 'Waiting for partitions to be created...'
  tries=0
  while [ ! -e /dev/nbd4p1 -a $tries -lt 60 ]; do                                                                                                             
      sleep 1
      tries=$((tries+1))                                                                                                                                  
  done
  echo "mounting image..."
  mount /dev/nbd4p1 $TMP_DIR
  echo 'Tarring up image...'
  tar -Sczpf u-${OUTPUT_OS_VERSION}-0-k-${IMAGE_K8S_VERSION}-0.tar.gz --selinux -C $TMP_DIR  .                                                                                            
  echo 'Unmounting image...'
  umount $TMP_DIR                                                                                                                                         
  qemu-nbd -d /dev/nbd4
  rmdir $TMP_DIR

Of course, you need to change the variables names in this code snippet.

[vasartori]

A thing I forgot:

If you are generating a EFI image, you need to mount the secound partition at TMP_DIR

  mount /dev/nbd4p2 $TMP_DIR

Otherwise, you will generate a image with uefi partition

[JonnyBGod]

I am trying the following configs:

#!/usr/bin/bash

set -euox pipefail

if [ "$#" -eq 0 ]; then
    echo "No kubernetes version supplied, exiting"
fi


for arg; do
  printf 'Begin image generation for k8s version "%s"\n' "$arg"
  export K8S_VERSION=$arg

  export K8S_DEB_VERSION="${K8S_VERSION}-1.1"

  if [[ "${K8S_VERSION}" =~ ^[0-9]\.[0-9]{0,3}\.[0-9]{0,3}$ ]]; then
      echo "Valid k8s version"
  else
      echo "Invalid k8s version"
      exit 1
  fi

  export K8S_SERIES=`echo "${K8S_VERSION}" | awk 'BEGIN {FS="."; OFS="."} {print $1,$2}'`
  export IMAGE_K8S_VERSION=`echo "${K8S_VERSION}" | awk 'BEGIN {FS="."; OFS=""} {print $1,$2,$3}'`
  export OUTPUT_OS_VERSION="2204"

  cat ./packer/qemu/qemu-ubuntu-${OUTPUT_OS_VERSION}.json | jq ". + {\"kubernetes_deb_version\": \"${K8S_DEB_VERSION}\", \"kubernetes_semver\": \"v${K8S_VERSION}\", \"kubernetes_series\": \"v${K8S_SERIES}\"}" > ./packer/qemu/qemu-ubuntu-$OUTPUT_OS_VERSION.json.tmp
  mv ./packer/qemu/qemu-ubuntu-${OUTPUT_OS_VERSION}.json.tmp ./packer/qemu/qemu-ubuntu-${OUTPUT_OS_VERSION}.json

  cat ./packer/qemu/qemu-ubuntu-${OUTPUT_OS_VERSION}.json

  make deps-qemu
  export PACKER_LOG=1
  PATH=$PATH make build-qemu-ubuntu-${OUTPUT_OS_VERSION}

  TMP_DIR=$(mktemp -d /tmp/packer-maas-XXXX)
  echo 'Binding packer qcow2 image output to nbd ...'
  modprobe nbd
  qemu-nbd -d /dev/nbd4
  qemu-nbd -c /dev/nbd4 -n ./output/ubuntu-${OUTPUT_OS_VERSION}-kube-v${K8S_VERSION}/ubuntu-${OUTPUT_OS_VERSION}-kube-v${K8S_VERSION}
  echo 'Waiting for partitions to be created...'
  tries=0
  while [ ! -e /dev/nbd4p1 -a $tries -lt 60 ]; do
      sleep 1
      tries=$((tries+1))
  done
  echo "mounting image..."
  mount /dev/nbd4p1 $TMP_DIR
  echo 'Tarring up image...'
  tar -Sczpf ./output/u-${OUTPUT_OS_VERSION}-0-k-${IMAGE_K8S_VERSION}-0.tar.gz --selinux -C $TMP_DIR  .
  echo 'Unmounting image...'
  umount $TMP_DIR
  qemu-nbd -d /dev/nbd4
  rmdir $TMP_DIR

  echo "cleaning image outputs directory"

  rm -rf ./output/ubuntu-${OUTPUT_OS_VERSION}-kube-v${K8S_VERSION}/
done

also tried the EFI variant and:

#!/bin/sh

sudo apt install -y qemu-kvm
sudo chmod 666 /dev/kvm

UBUNTU_VERSION="2204"
K8S_VERSION="1.29.2"
IMAGE_K8S_VERSION=`echo "${K8S_VERSION}" | awk 'BEGIN {FS="."; OFS=""} {print $1,$2,$3}'`

docker pull jonnybgod/maas-builder:latest
