This tutorial shows how to install MicroStack 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
Caution: Any change in IP address of the local host will be detrimental to the deployment. A virtual host will generally have a more stable address.
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.
