devstack on Ubuntu 22.04LTS

About

Devstack is a lightweight one-machine (VM) version of Openstack, especially suitable for developers who have a need to dive into Openstack without committing to the large overhead of a full system.

Create a Ubuntu 22.04LTS VM on your computer. (I've only tested this with Intel processors).

Assign at least 4 vCPU cores, 8 GB Ram and a 60GB disk.

git clone https://opendev.org/openstack/devstack
cd devstack/tools
sudo ./create-stack-user.sh
cd ../..

Sanity checks and Installation

sudo su - stack
cd /opt/stack/devstack
./stack.sh
. ./openrc

Some test commands to see that everything is as it should be

openstack network list  # should show public and private networks
openstack image list

Download Ubuntu 22.04 Cloud Image (QCOW2 format)

[download] https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img

Customize root user password so we can log in through console later (lets set a simple default)

sudo apt install guestfs-tools
sudo virt-customize -a jammy-server-cloudimg-amd64.img --root-password password:ubuntu2024

Create a Openstack Deployable Image like this

Create a custom Flavor for the image

Create Node 1 and Node 2 servers

openstack server create --image $(openstack image list | awk '/ Ubuntu-22.04LTS / {print $2}') --flavor clite --nic net-id=$(openstack network list | awk '/ private / {print $2}') node1
openstack server create --image $(openstack image list | awk '/ Ubuntu-22.04LTS / {print $2}') --flavor clite --nic net-id=$(openstack network list | awk '/ private / {print $2}') node2
openstack server list # Take note of the IP addresses, so we can SSH in later

# add secgroup rules to allow ssh etc..
openstack security group rule create default --protocol icmp
openstack security group rule create default --protocol tcp --dst-port 22:22
openstack security group rule create default --protocol tcp --dst-port 80:80

SSH into the servers, and install i.e. Nginx.
