The [tailscale documentation](https://tailscale.com/kb/1054/dns/) has two suggestions for this:
-- use their magicDNS feature / split DNS
-- setup a subdomain on a public domain
+- use their magicDNS feature / split DNS
+- setup a subdomain on a public domain
Since I already have a public domain that I use for my home network, I decided to go with the second option (I'm also uncertain how to achieve my goal using magicDNS without running tailscale inside the container).

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:
-- the environment variable `GCP_SERVICE_ACCOUNT_FILE`: it contains the credentials so that `traefik` can update the DNS record for the challenge
-- the environment variable `GCP_PROJECT`: the name of the GCP project
-- mounting the service account file inside the container (I store it on the host under `/data/containers/traefik/config/sa.json`)

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:
