 For routing the traffic I use [traefik](https://traefik.io/). The configuration for traefik looks like this:

 The important bit here is the `certificatesResolvers` part. I'll be using the [dnsChallenge](https://doc.traefik.io/traefik/user-guides/docker-compose/acme-dns/) instead of the [httpChallenge](https://doc.traefik.io/traefik/user-guides/docker-compose/acme-http/) to obtain the certificate from let's encrypt. For this to work, I need to specify the `provider` to be [gcloud](https://go-acme.github.io/lego/dns/gcloud/). I'll also need a service account (see [this doc](https://cloud.google.com/docs/authentication/production#providing_credentials_to_your_application) to create it). I run `traefik` in a docker container, and the `systemd` unit file is below. The required bits for using the `dnsChallenge` with `gcloud` are:

 As an example, I run [grafana](https://grafana.com/) on my home network to view metrics from the various containers / hosts. Let's pretend I use `example.net` as my domain. I want to be able to access `grafana` via <https://dash.example.net>. Here's the `systemd` unit configuration I use for this:

 Now I can access my grafana instance via HTTPS (and <http://dash.example.net> would redirect to HTTPS) while my tailscale interface is up on the machine I'm using (e.g. my desktop or my phone).
