Set up your environment

Superset and its backing services all run on Kubernetes. In this step you install MicroK8s, bootstrap a Juju controller on it, and create the model used throughout the tutorial.

Install MicroK8s

MicroK8s is a lightweight Kubernetes distribution that runs on a single host. Install it and grant your user access:

sudo snap install microk8s --channel 1.34-strict/stable
sudo usermod -aG snap_microk8s $USER
newgrp snap_microk8s
sudo microk8s enable dns
sudo microk8s enable hostpath-storage

Wait until all MicroK8s services report as running:

microk8s status --wait-ready

Optionally, alias the Kubernetes CLI so you can call it as kubectl:

sudo snap alias microk8s.kubectl kubectl

Install Juju and bootstrap the controller

Juju is the orchestration engine that drives the charms. Install it and bootstrap a controller into your MicroK8s cloud:

sudo snap install juju --channel 3/stable
juju bootstrap microk8s superset-controller

Juju recognizes a MicroK8s cloud automatically. If it does not appear in juju clouds, register it manually with juju add-k8s microk8s.

Create a model

Create the model that holds the tutorial deployment. Juju creates a Kubernetes namespace with the same name:

juju add-model superset-tutorial

Verify the result:

juju status

Model              Controller           Cloud/Region        Version  SLA          Timestamp
superset-tutorial  superset-controller  microk8s/localhost  3.6.12   unsupported  16:05:03+01:00

Model "admin/superset-tutorial" is empty.

Your environment is ready. Continue to deploy the supporting charms.
