How could I bind docker container to specific external interface

Here’s something from the docker docs

https://docs.docker.com/v17.09/engine/userguide/networking/default_network/binding/

If you want to be more restrictive and only allow container services
to be contacted through a specific external interface on the host
machine, you have two choices. When you invoke docker run you can use
either -p IP:host_port:container_port or -p IP::port to specify the
external interface for one particular binding.
Or if you always want Docker port forwards to bind to one specific IP address, you can edit your system-wide Docker server
settings and add the option --ip=IP_ADDRESS. Remember to restart your
Docker server after editing this setting.
