Hi, I'm the author of the blog post being promoted here.
The `clouflared tunnel route dns` command creates thee DNS record mapping the tunnel to the domain. The tunnels config maps the hostname to the local service, and you can have multiple of those for each service. So for the example above, you would create a DNS record for each domain pointing to the same one tunnel, and that tunnel will route based on the ingress rules.
