Getting Started with microk8s (Ubuntu)

This is an end-to-end guide on how to test Araali on Canonical’s MicroK8s and use an opensource microservice app (sockshop).

Install MicroK8s

Start with a VM running Ubuntu. For demonstration purposes, Ubuntu 21.10 is used here. Install MicroK8s with the following command to get periodic snap updates of Microk8s to ensure compatibily with newer Ubuntu releases:

sudo snap install microk8s --classic --channel=latest/stable

Join the Group

sudo usermod -a -G microk8s $USER sudo chown -f -R $USER ~/.kube

Exit and log back to the VM

Check if microk8s is up

microk8s status --wait-ready

If the above command does not return any output, it is likely that an error occured. Remove the same command without the --wait-ready flag to know any errors and/or warnings.

Create a link/alias: sudo snap alias microk8s.kubectl kubectl

Now use mkctl like kubectl. If you DONT want the alias then use “microk8s.kubectl” command similar to “kubectl”

Enable the dns and ingress services

microk8s enable dns

microk8s enable ingress

Install Araali and start the assessment

Follow the instructions in the getting started post

Install an Opensource App

Download sock-shop from Github

git clone https://github.com/ashish234/sock-shop.git

Create a namespace: mkctl create ns sock-shop

Deploy the yaml file

mkctl apply -f sock-shop/sock-shop.yaml -n sock-shop

Look into the services and mark the port for NodePort service “front-end”

In this case its running on 30001

Open a browser and type your VM’s IP:30001
