TLS certificates are the basis of identity, and thus trust, in everything Linkerd does—but what exactly are they, and what do you need to know to keep everything running smoothly? In this workshop, we’ll take a close look at what TLS certificates are, why they’re important, how Linkerd uses them, and everything you need to know to keep Linkerd running smoothly and securely.
We’ll cover manual management and how to use cert-manager to help out. Join us for an engaging and detailed look at this critical aspect of Linkerd!
This is a hands-on workshop, so it's important that you arrive prepared with a Kubernetes cluster (pretty much any kind will do!) and the Linkerd CLIs installed on your machine! We'll use Buoyant Enterprise for Linkerd version 2.18, but Linkerd edge releases starting with edge-25.4.4 will work just fine, too. Check out the BEL Getting Started Guide for specific instructions on how to set that up. (As always, if you don’t want to do the hands-on portion, you are welcome to just listen in. But it won’t be as fun!)
