Tailscale Desktop not assigning unique static IPs per device

[jeffkni]

Setup

• Docker Desktop with Tailscale extension v0.0.13
• Start containers with docker-compose - no networking specified; each container has a name in docker-compose
• Each container shows a unique name in docker desktop as expected ✅

Expected

• Tailscale also gives each container a unique ip -> magic dns name

Actual

• Tailscale gives them all the same 100. IP address:

  

• Enabling MagicDNS shows they're all assigned to the same docker-desktop dns name (host networking is not enabled):

That is how the Docker Desktop extension works: there is one tailscaled, running in a Linux instance inside Docker Desktop. It forwards individual ports to each container.

It is not running a proxy tailscaled for each container. Even in the demo video linked to, all of the containers are on the same IP address with the same URL but different port numbers.

To have each container to have its own IP address and appear on the tailnet as an individual node, one could run tailscale inside each Docker container.

Thanks for the clarification @DentonGentry

I think this is resolved.
