+[direnv](https://direnv.net/) will make it so anytime you `cd` to your repo's directory it export the required environment variables (e.g. `KUBECONFIG`). To set this up make sure you [hook it into your shell](https://direnv.net/docs/hook.html) and after that is done, run `direnv allow` while in your repos directory.

 ### 🌐 DNS
 
 📍 The [external-dns](https://github.com/kubernetes-sigs/external-dns) application created in the `kube-system` namespace will handle creating public DNS records. By default, `echo-server` is the only public domain exposed on your Cloudflare domain. In order to make additional applications public you must set an ingress annotation like in the `HelmRelease` for `echo-server`. You do not need to use Terraform to create additional DNS records unless you need a record outside the purposes of your Kubernetes cluster (e.g. setting up MX records).
