How to deploy on Sunbeam

Duration : Up to 60 minutes depending on internet download speed.

This guide goes through the steps for setting up Sunbeam and deploying Charmed PostgreSQL.

Prerequisites

  • A physical or virtual machine running Ubuntu 22.04+
    • If you’d like to follow this guide in an isolated test environment, you can launch a Multipass instance.
  • Hardware requirements depend on planned deployment size.
    • Recommended: 8 CPU cores, 32GB RAM, 100GB of storage
    • Minimum: See the requirements listed in the Sunbeam documentation

Steps


Install and bootstrap Sunbeam

Follow the official OpenStack guide: Single-node deployment.

Pay attention to the Caution and Note sections - the /etc/hosts will require a manual fqdn fix.

Enable OpenStack Images Auto-sync

Follow the official Images Sync guide to enable auto-sync and wait for the image 22.04 to be downloaded.

Set up Juju inside an OpenStack bastion

Follow the MicroStack guide Manage workloads with Juju from the beginning, and stop after the section “Create a Juju controller”.

To summarize, the relevant sections are:

  • Set up the bastion
  • Install and configure the Juju client
  • Create a Juju controller

Deploy Charmed PostgreSQL

Add a model if you don’t have one already, and deploy a PostgreSQL cluster. Use the -n flag to specify number of units.

juju add-model postgresql
juju deploy postgresql --base ubuntu@22.04 -n 3

Sample output of juju status --watch 1s:

Model       Controller     Cloud/Region       Version  SLA          Timestamp
postgresql  my-controller  sunbeam/RegionOne  3.5.4    unsupported  19:42:44Z

(Optional) Access the OpenStack dashboard

Follow the official guide: Accessing the OpenStack dashboard.

When using a Multipass VM, you may need to manually route OpenStack IPs. For example:

sudo ip route add 10.10.10.0/24 via 10.76.203.210 

where 10.76.203.210 is the IP of the Multipass VM and 10.10.10.0 is the network returned by sunbeam dashboard-url.

The image below is an example of the OpenStack dashboard view (bastion + juju controller + 3 postgresql nodes):
