Debian OpenStack Installer for home lab
---------------------------------------

1. Install Debian 12 (Bookworm) on a physical machine.

We will use same network interface for host and virtual machines.

/etc/network/interfaces
-------------------------------
...
allow-hotplug eno1
iface eno1 inet static
    address 192.168.0.155
    broadcast 192.168.0.255
    netmask 255.255.255.0
    gateway 192.168.0.1
    dns-nameservers 192.168.0.1
--------------------------------

external

 eno1

  -------> static IP: 192.168.0.155


2. edit "openstack_setup.sh" and set the following setting:

OPENSTACK_HOST_IP="192.168.0.155"
EXTERNAL_BRIDGE_INTERFACE="eno1"

# chmod +x openstack_setup.sh
# ./openstack_setup.sh &> output.txt

check output from another shell
# tail -f output.txt

restart and start exploring openstack on Debian.


3. Check "next_steps" for networking and launching your first instance.
