Here's how to install the PoC on your machine. 1/ Make sure all your keys are in /root/.ssh/authorized_keys of your host The file will be copied in the PXE server image, and in the Debian live image to boot all VMs. 2/ Install the repo and package Run this script, or do what it does manually: #!/bin/sh set -e openstack_release=rocky debian_release=stretch echo "deb http://${debian_release}-${openstack_release}.debian.net/debian ${debian_release}-${openstack_release}-backports main deb-src http://${debian_release}-${openstack_release}.debian.net/debian ${debian_release}-${openstack_release}-backports main deb http://${debian_release}-${openstack_release}.debian.net/debian ${debian_release}-${openstack_release}-backports-nochange main deb-src http://${debian_release}-${openstack_release}.debian.net/debian ${debian_release}-${openstack_release}-backports-nochange main " >/etc/apt/sources.list.d/openstack.list apt-get update apt-get install -y --allow-unauthenticated openstack-backports-archive-keyring apt-get update apt-get install -y apt-get install openstack-cluster-installer-poc After install, you normally have all of the dummy network and bridge up and running to host all of the VMs. If you need to change the network settings, undo the network setup: # /etc/init.d/oci-poc-virtual-network stop Edit the settings: # $EDITOR /etc/oci-poc/oci-poc.conf and re-apply the settings: # /etc/init.d/oci-poc-virtual-network start You will at least need to edit PRIMARY_DNS, SECONDA_DNS, GUESTS_DOMAIN_NAME, DEBIAN_MIRROR_HOST. Everything else can stay untouched. Eventually, you may also change NUMBER_OF_GUESTS. 3/ Run the install script # oci-poc-setup Running this script will: * Create a PXE server node .qcow2 image in /var/lib/openstack-cluster-installer/poc/templates * Create an empty 10GB HDD .qcows2 image at the same location * Start /etc/init.d/oci-poc-vms. Note that at this point, this script may fail, but that's kind of ok. If it happens, break it, kill it, kill all the VMs and remove the PID files in /var/run/oci-poc. 4/ Launch the VMs Simply run the init script: # /etc/init.d/oci-poc-vms manual-start This will: * Copy qcow2 files from /var/lib/openstack-cluster-installer/poc/templates to /var/lib/openstack-cluster-installer/poc/runtime. * Start the PXE server VM and wait until it replies to ssh. * Configure openstack-cluster-installer's db access (ie: create the db, configure the oci's config file to access to it, initialize the db). * Starts all slave nodes. If everything goes well, you'll be able to browse the web interface: http:///oci/ and it will show nodes booted on the live system.
