Single-node quickstart

This tutorial shows how to install MicroStack (based on project Sunbeam) in the simplest way possible. It will deploy an OpenStack 2023.1 (Antelope) cloud.

The cloud will only allow access to its VMs from the local host. To enable access from any host on your network, follow the Single-node guided tutorial instead.

Requirements

You will need a single machine whose requirements are:

• physical or virtual machine running Ubuntu 22.04 LTS
• a multi-core amd64 processor ideally with 4+ cores
• a minimum of 16 GiB of free memory
• 50 GiB of SSD storage available on the root disk

Deploy the cloud

Install the openstack snap

Begin by installing the openstack snap:

sudo snap install openstack --channel 2023.1

Prepare the machine

Sunbeam can generate a script to ensure that the machine has all of the required dependencies installed and is configured correctly for use in MicroStack - you can review this script using:

sunbeam prepare-node-script

or the script can be directly executed in this way:

sunbeam prepare-node-script | bash -x && newgrp snap_daemon

The script will ensure some software requirements are satisfied on the host. In particular, it will:

• install openssh-server if it is not found
• configure passwordless sudo for all commands for the current user (NOPASSWD:ALL)

Bootstrap the cloud

Deploy the OpenStack cloud using the cluster bootstrap command and accept software defaults:

sunbeam cluster bootstrap --accept-defaults

Configure the cloud and obtain credentials

Now configure the deployed cloud using the configure command:

sunbeam configure --accept-defaults --openrc demo-openrc

The above command provides normal user credentials (file demo-openrc). Admin credentials can be obtained in this way (file admin-openrc):

sunbeam openrc > admin-openrc

Launch a VM

Verify the cloud by launching a VM called ‘test’ based on the ‘ubuntu’ image (Ubuntu 22.04 LTS). The launch command is used:

sunbeam launch ubuntu --name test

Sample output:

Launching an OpenStack instance ...
Access instance with `ssh -i /home/ubuntu/.config/openstack/sunbeam ubuntu@10.20.20.200`

Connect to the VM over SSH using the provided command. Note that the VM will not be ready instantaneously; waiting time is mostly determined by the cloud’s available resources.
