Configuration

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
