Tailscale: Publish Dockerfile to enable docker pull tailscale

[cee-dub]

Is your feature request related to a problem? Please describe.

It's fantastic that this repo has a Dockerfile. It is frustrating to have to clone the repo to use it.

Describe the solution you'd like

Publish the image on Docker Hub to make docker pull tailscale:tailscale work.

Describe alternatives you've considered

Self publishing from a fork? Seems like doing it from the source of truth is probably best.

I tried to register the "Docker ID" of "tailscale" on hub.docker.com but apparently it's already taken, but this is a 404: https://hub.docker.com/tailscale

Do I not understand what a "Docker ID" is?

This works differently than I remember doing this last.

The "tailscale" org already exists, and we own it :). We just haven't pushed any repos yet, so the hub's weird about showing anything.

I created an empty tailscale repo, so https://hub.docker.com/r/tailscale/tailscale is visible now - albeit empty.

Great. Want to invite me to push to it? https://hub.docker.com/u/bradfitz

We're going to put this on hold until we have better container support (#504)

In the mean time, (and for simple vanilla-docker use cases only) I wrote a balena service to test out for our edge nodes. It's been working great so far.

I also needed to run this via Docker, as Flatcar (former CoreOS) can pretty much only run container workloads.

I'm publishing (only amd64) Docker image here: https://github.com/function61/tailscale-dockerimage
