This helped fix a helm upgrade from 9.14.1 to 10.3.2 corrresponding to traefik 2.4.2 to 2.5.1

Traefik 2.4 to 2.5 includes CRD updates and are mentioned in the migration notes

In case of updates check https://github.com/traefik/traefik/tree/v2.5/docs/content/reference/dynamic-configuration

This file contained references to required CRDs

Ubuntu 20.04 + Autoinstall + VirtualBox

Intro

This guide will explain how to set up a [VirtualBox][] VM running [Ubuntu 20.04][] and, using the new [autoinstall][] tool and cloud-init, install OpenSSH server, add a group and a user, who can then connect to the machine via SSH. This was done on a 2016 MacBook Pro running macOS 10.15 "Catalina" and VirtualBox 6.1.6 (with the VirtualBox Guest Additions installed).

You will also need a group name, a username, a password hash and an SSH key pair.

How Autoinstall Works
