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

A more complete example (with rewriting cookie domains/paths) can be found at http://blog.haproxy.com/2014/04/28/howto-write-apache-proxypass-rules-in-haproxy/

We will try something roughly equivalent to the following ProxyPass directives in Apache2:

ServerName www.example.com
...
ProxyPass        /foo/  http://foo.local
ProxyPassReverse /foo/  http://foo.local

In haproxy.cfg we define a backend, say foo, to reverse-proxy to foo.local backend server.
