"Dance like nobody's watching; encrypt like everyone is." If you want to follow this sound advice, you can leverage the famous Let's Encrypt, which lets you obtain free TLS certificates using a protocol called ACME.
We're going to explain how that ACME thing works; then we will see how to use it in practice on a Kubernetes cluster, by leveraging Traefik (as an Ingress controller and load balancer) and cert-manager. In particular, we will show what to add to an Ingress resource to enable TLS in a fully automated way. You sprinkle a tiny bit of YAML, cert-manager and Traefik make the magic happen!
Demos, there will be. (Lots thereof!)

When he's not busy with computers, he collects musical instruments. He can arguably play the theme of Zelda on a dozen of them.
