• Simply download the desired image, decompress, and flash to an sd card

  # List latest available release asset names, select one and export as an env var $NAME
  curl -s https://api.github.com/repos/mbmcmullen27/raspberry-pi-images/releases/latest | jq '.assets[].name'
  export NAME=raspios-ssh-enabled.tar.gz
  
  # Download the archive
  curl -s https://api.github.com/repos/mbmcmullen27/raspberry-pi-images/releases/latest \
      | jq -r --arg NAME = "$NAME" '.assets[] | select( .name == $NAME).browser_download_url' \
      | wget -qi -
      
  # Extract image and flash the card
  tar -xvf $NAME
  sudo dd if=docker/src/custom-raspios-arm.img of=/dev/<SD CARD DEVICE NAME> bs=4M status=progress conv=fsync

Running Templates Locally With Packer

• initialize packer build machine with following these instructions

  • needs:
    • qemu-user-static
    • qemu-utils
    • packer-builder-arm
      • installed into ~/.packer.d/plugins

• use fetch-image.sh script to update the packer template with the latest raspios release and build

  # usage 
  ./fetch-image.sh -h
  
  cd pi-imager
  ./fetch-image -u
  ./fetch-image -b

Running Builder With Docker

• See packages for latest image tag
• Provide an install script to be run on the base image with packer

docker run \
    --privileged=true \
    -v /dev:/dev \
    -v $(pwd)/src:/home/builder/src \
    -e script=<image-init-script>
    -it ghcr.io/mbmcmullen27/raspberry-pi-images:<latest image tag>
