Charmed PostgreSQL Tutorial > 1. Set up the environment
Set up the environment
In this page, we will set up a development environment with the required components for deploying Charmed PostgreSQL K8s.
Before we start, make sure your machine meets the minimum system requirements.
Summary
Set up Multipass
Multipass is a quick and easy way to launch virtual machines running Ubuntu. It uses the cloud-init standard to install and configure all the necessary parts automatically.
Install Multipass from Snap:
sudo snap install multipass
Launch a new VM using the charm-dev cloud-init config:
multipass launch --cpus 4 --memory 8G --disk 50G --name my-vm charm-dev
Note: All ‘multipass launch’ parameters are described here.
The Multipass list of commands is short and self-explanatory. For example, to show all running VMs, just run the command multipass list.
As soon as a new VM has started, access it using
multipass shell my-vm
Note: If at any point you’d like to leave a Multipass VM, enter Ctrl+D or type exit.
All necessary components have been pre-installed inside the 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.
Set up Juju
Let’s bootstrap Juju to use the local MicroK8s controller. We will call it “overlord”, but you can give it any name you’d like.
juju bootstrap microk8s overlord
A controller can work with different models. Set up a specific model for Charmed PostgreSQL K8s named ‘tutorial’:
juju add-model tutorial
You can now view the model you created above by running the command juju status. You should see something similar to the following example output:
Model Controller Cloud/Region Version SLA Timestamp
tutorial overlord microk8s/localhost 3.1.7 unsupported 11:56:38+01:00
Model "admin/tutorial" is empty.
