Simple qemu and ansible powered set of scripts to build and configure raspios images.

Scripts collection to modify the raspios image:

• mounts the image to perform some initial modifications
• boots on it using qemu
• runs ansible playbooks through qemu
• converts the qemu image back to .img format
• writes the image to the device/sdcard (using dd)

• ansible
• qemu

• ansible-role-security: source for the ssh and auto-updates tasks
• qemu-rpi-kernel: raspi kernel modified to boot on qemu (used for the online customization)
• raspberry linux kernel
• raspios

Full build: download latest media, apply changed, and flash to SD Card

Download latest media and requirement qemu kernel

Mount the .img and perform offline customizations to the OS:

• Enable ssh on boot
• Rename pi user to $IMAGE_USER
• Add public key located at $SSH_PUBKEY to $IMAGE_USER's authorized keys

Convert .img file to qemu image

Boots the image on qemu

Runs $ANSIBLE_PLAYS playbook list on the qemu booted image

Converts back qemu image to .img

Flashes $IMAGE_NAME to $TARGET_DEVICE

Deletes all temporary and intermediate files

pimaker configuration is performed through the environment variables in config.env:

• IMAGE_NAME: name for the target .img file to create
• IMAGE_USER: name of the main user to replace the stock pi user
• IMAGE_SIZE: size of the target device. If $TARGET_DEVICE is defined then the size will be discovered automatically
• SSH_PUBKEY: path to the ssh public key to add to $IMAGE_USER's authorized_keys file
• QEMU_SSH_PORT: local port to map to qemu's port 22 (used for ansible to connect to the image and run playbooks
• TARGET_DEVICE: path to the device on the host OS. If defined, will be used to find $IMAGE_SIZE and pimaker will flash the created img to this device using dd
