Tailscale-UDMPro

A Guide to running Tailscale on a UDM(Pro)

Prerequisites

• Install On-Boot scripts

• Update CNI plugins

Configure Network interfaces

The on-boot script attatched to this repo can be used as an example. Due to the host networking stack not being compatible with Tailscale, routes will have to be configured manually. The container is given a local IP address and any Tailscale IP's or subnet routes can be pointed to the container via ip route

The container is giving a local IP by creating a macvtap network tailscale.conflist for the container in /mnt/data/podman/cni. See the example tailscale.conflist file in this repository

Replace the IP values for your environment in tailscale.conflist and 06-tailscale.sh.

Create Tailscale Image

Tailscale provided ARM64 docker images now. You can pull the latest docker image using the following command

docker pull tailscale/tailscale

Create Container

Persistent storage is needed to store the logs & state file. Tailscale will create it's own folder in the path you specify.

I use /mnt/data/docker as the base for all my containers. The example below will store the files in /mnt/data/docker/tailscale

docker run -d --name=tailscaled \
--cap-add=NET_ADMIN \
--cap-add=SYS_MODULE \
-v /mnt/data/docker:/var/lib \
-v /dev/net/tun:/dev/net/tun \
--network=tailscale \
--privileged \
tailscale/tailscale tailscaled

Start Container

To start the container, execute the sh file you have updated with the values for your environment.
