Maybe „Quick Start with k8s"?

Why would you install an old version?

I have installed the traefik for a long time, in 2021 or 2022, I am trying to upgrade but found the traefik have many products. I should read the traefik labs docs, I remember the traefik only have one type of document in previous year.
