Running Tailscale docker image vs. binding port to Tailscale IP (lemmy.ml)

So Tailscale has this whole series about hosting services on one's Tailnet using Docker. Their approach is to run Tailscale in Docker and have the services' containers share its namespace by setting network_mode: service:<tailscale_service_name>.

I am trying to understand why this is better than just binding the service's port to the Tailscale IP of the host device, given that option is not even mentioned in any of their blog posts.

The only advantage I can think of is that you get to have different Tailscale rules/configurations for different services. In my case, this is not an advantage because I will run Tailscale on the host anyway and I won't have different configurations for each service.

Can anyone help me understand?

I only have experience trying to run two Tailscale containers on the same machine and hit so many roadblocks that running it containerized just wasn’t worth it.

Containerizing is probably only worth it if you have an explicit need for it.
