while keeping master README ADMIN_PASSWORD / boot rules and not
publishing admin :81 by default.

 Without those env overrides the binary still defaults to admin `127.0.0.1:8081` and proxy `:8080` / `:18443` inside the container.

+Publishing admin (`-p 81:81`) also needs `-e ADMIN_HOST=0.0.0.0`. Do not publish :81 on untrusted networks.
