[LAB] microk8s with pod security policies

Introduction

This laboratory is developed to have a first contact with the Pod Security Policies locally using microk8s.

LAB assumptions and requirements

This lab assumes you have basic knowledge about kubernetes, RBAC and basic linux commands and concepts. As a requirement, you must have installed (default installation) microk8s on your linux PC. Then enable the dns microk8s plugin: microk8s.enable dns.

To check that microk8s is running correctly, execute the following command, you should have an output like the one shown below:

$ sudo microk8s.inspect
