Just thought I'd put together some detail on deploying Tailscale using Docker and Portainer. These bits-and-pieces are available elsewhere, but not together, so hopefully this will save someone a bit of time if you'd like to add Tailscale to an existing Docker install:

Here's my annotated recommended docker-compose, to use with Portainer-Stacks. Note that I'm not using a pre-made Auth Key. I started that way, but realized it was very easy to simply check the Portainer log for the tailscaled container once the stack is running. In that log you'll see the standard Auth link that you can use to authorize the container. This way you don't need to create a key in advance, or create a reusable key that introduces a security risk:

version: '3.9'
services:
  tailscale:
    image: tailscale/tailscale
    container_name: tailscaled

Linux Performance Tweaks

1. Install ipset to manage ipstables lists

apt install ipset

2. Install iptables-persistent to preserve iptables rules on reboot

1. switch nginx image to openresty/openresty

2. add the following to server/location (/etc/nginx/conf.d/default.conf)

   set $req_header "";
   set $resp_header "";
   header_filter_by_lua_block{ 
      local h = ngx.req.get_headers();
      for k, v in pairs(h) do
         ngx.var.req_header = ngx.var.req_header .. k.."="..v.." ";
