<p>I apologize for my inexperience, but I need to ask a question and I believe this is the right place. I set up a HA k3s cluster with 1 master and 2 replicas, but I've been told that I must put a load balancer in front of this infrastructure to avoid service disruption in case of failovers. I would like to use a high-availability configuration for the load balancer too, as I would like to avoid single points of failure. Does anybody know about open-source tools providing a high available load balancer? Thank you in advance.</p>

<p>If you are on bare metal, one open source tool that implements the Load Balancer feature in kubernetes and AFAIK supports k3s is <code>metallb</code>.
Take a look at the <a href="https://metallb.universe.tf/" rel="nofollow noreferrer">official documentation</a> to get started.</p>
