At N1 Analytics we use Kubernetes for running experiments, continuous integration testing and deployment. In this post I document setting up a Kubernetes cluster to automatically provision TLS certificates from Let's Encrypt using Jetstack's Certificate Manager, the helm package manager and the nginx-ingress controller.
I wrote this after migrating our cluster from traefik to use cert manager and nginx-ingress. The end state will be one where we can create Kubernetes ingress with a TLS certificate with only a set of annotations in the respective helm template.
I'm going to assume some background knowlege for this post, if you haven't heard of [Let's Encrypt](https://letsencrypt.org/abou
