    --increment=<nb>                  set a nb of images you whant to generate, this auto increment hostname and mac addresse

    --enable-qemu-aarch64             set arch to arm64
    --enable-qemu-arm                 set arch to armhf

    --enable-debug                    show debug msg and config file during the process

    --version                         print a current version of ./cluster.sh

 cmd:
    build                             build packer image <all|raspios|ubuntu>
    show ip                           list all raspberry pi ip + mac addresses of your local network
