Tailscale image - podman build fails

[cmonty14]

Hi,
I'm trying to deploy Tailscale docker image on Ubuntu 22.04 using podman.
The instructions are simple and clear:

1. docker pull tailscale/tailscale:stable
2. docker build -t tailscale/tailscale .
3. docker run -d --name=tailscaled -v /var/lib:/var/lib -v /dev/net/tun:/dev/net/tun --network=host --cap-add=NET_ADMIN --cap-add=NET_RAW tailscale/tailscale

Here the first issue occurs:
Error: stat /home/thomas/Dockerfile: no such file or directory

However I can run docker run -d --name=tailscaled -v /var/lib:/var/lib -v /dev/net/tun:/dev/net/tun --network=host --cap-add=NET_ADMIN --cap-add=NET_RAW tailscale/tailscale and the container is available with podman ps -a.

CONTAINER ID  IMAGE                                 COMMAND               CREATED         STATUS                     PORTS       NAMES
3d73bf91169f  docker.io/tailscale/tailscale:latest  /usr/local/bin/co...  24 minutes ago  Exited (1) 23 minutes ago              tailscaled

Can you please advise what's wrong here?
Is `docker build¸ required?

If you pull the image then probably no reason to build.

Error: stat /home/thomas/Dockerfile: no such file or directory
means you don't have a Dockerfile or Containerfile to build with, so do not need to build.

Also are you using alias docker=podman or actually using podman.

Does the podman run command work, then you are all set.

I'm using alias docker=podman.
