This is part of the Charmed MySQL K8s Tutorial. Please refer to this page for more information and the overview of the content.

Minimum requirements

Before we start, make sure your machine meets the following requirements.

Multipass environment

Multipass is a quick and easy way to launch virtual machines running Ubuntu. It uses “cloud-init” standard to install and configure all the necessary parts automatically.

Let’s install Multipass from Snap and launch a new VM using “charm-dev” cloud-init config:

sudo snap install multipass && \
multipass launch --cpus 4 --memory 8G --disk 30G --name my-vm charm-dev

Note: all ‘multipass launch’ params are described here.

Multipass list of commands is short and self-explanatory, e.g. show all running VMs:

multipass list

As soon as new VM started, enter inside using:

multipass shell my-vm

Note: if at any point you’d like to leave Multipass VM, enter Ctrl+d or type exit.

All the parts have been pre-installed inside VM already, like MicroK8s and Juju (the files ‘/var/log/cloud-init.log’ and ‘/var/log/cloud-init-output.log’ contain all low-level installation details). The Juju controller can work with different models; models host applications such as Charmed MySQL K8s. Set up a specific model for Charmed MySQL K8s named ‘tutorial’:

juju add-model tutorial

You can now view the model you created above by entering the command juju status into the command line. You should see the following:

Model     Controller  Cloud/Region        Version  SLA          Timestamp
tutorial  overlord    microk8s/localhost  2.9.38   unsupported  22:30:11+01:00
Model "admin/tutorial" is empty.
