Mod fails to initialize due to slow CURL

[Sirs0ri]

Hi!

Problem Description:

I recently noticed that some of my containers that should be part of my tailnet aren't, and after some investigating I found that the CURL command to download Tailscale times out after 10 minutes, and the installation of tailscale subsequently fails. I hope this is the right place to report this issue, if not I'd appreciate a pointer in the right direction!

Steps to reproduce:

The simplified version: run the curl command and a wget equivalent in a local terminal, and observe how much slower curl is:

$ curl https://pkgs.tailscale.com/stable/tailscale_1.74.1_arm64.tgz -o tailscale.tgz
$ wget https://pkgs.tailscale.com/stable/tailscale_1.74.1_arm64.tgz -O tailscale.tgz

The full repro: Run a basic nginx server through docker compose:

services:
  ts-timeout:
    image: linuxserver/nginx:latest
    environment:
      - DOCKER_MODS=ghcr.io/tailscale-dev/docker-mod:main
      - TAILSCALE_STATE_DIR=/var/lib/tailscale
      - TAILSCALE_HOSTNAME=ts-timeout
      - TAILSCALE_AUTHKEY=tskey-auth-your-key-here
    volumes:
      - ts_timeout:/var/lib/tailscale
    ports:
      - "8083:80" # use any free port here

volumes:
  ts_timeout:

Run the whole thing using docker compose up. You should see something like this:

$ docker compose up ts-timeout

The first request gets the current version and finishes quickly, the second one is the one to download the tarball, and it'll fail after 10 minutes.

Running the install script manually works (but that doesn't help much since I'd have to manually run it every time the container restarts).

I've got the same issue with my Jellyfin container:
