Getting started

Overview

This tutorial shows how to deploy a test Charmed OpenStack cloud. It’s major elements are:

• Ubuntu 20.04 LTS (Focal) for the cloud nodes

• OpenStack Yoga

• Ceph Quincy

OpenStack services will include Compute, Network, Block Storage, Object Storage, Identity, Image, and Dashboard.

Requirements

Hardware

You will need a MAAS cluster with four nodes:

• 1 x Juju controller node: 4GiB RAM, 2 CPUs, 1 NIC, 1 x 40GiB storage

• 3 x cloud nodes: 16GiB RAM, 4 CPUs, 2 NICs, 2 x 80GiB storage

Note

The smaller controller node can be targeted via Juju constraints at controller-creation time.

A single network interface is sufficient on the cloud nodes if an Open vSwitch bridge is set up in MAAS. See the MAAS page in the Deploy Guide for details.

Software

The software versions used in this tutorial are:

• MAAS 2.9.2

• Juju 2.9.29

Other prerequisites

• You should have Juju installed and be comfortable with its basic usage.

• Create directory ~/tutorial. All the files created in this tutorial will be placed there.

• The MAAS server must have Focal amd64 images available.

• You should be briefly acquainted with these concepts:

  • bundles

  • constraints

  • network spaces

Procedure

The procedure consists of the following steps:

• Collect local settings
• Configure the overlay bundle
• Prepare Juju
• Deploy OpenStack
• Configure OpenStack
• Verify the cloud
• Access the dashboard
