  This series of tutorials deals with networking standalone containers which bind
  directly to the Docker host's network, with no network isolation. For other
  networking topics, see the
  overview
  Goal
  The goal of this tutorial is to start a
  nginx
  container which binds directly
  to port 80 on the Docker host. From a networking point of view, this is the
  same level of isolation as if the
  nginx
  process were running directly on the
  Docker host and not in a container. However, in all other ways, such as storage,
  process namespace, and user namespace, the
  nginx
  process is isolated from the
  host.
  Prerequisites
  This procedure requires port 80 to be available on the Docker host. To make
  Nginx listen on a different port, see the
  documentation for the
  nginx
  image
  host
  networking driver only works on Linux hosts, and as an opt-in
  feature in Docker Desktop version 4.34 and later. To enable this feature in
  Docker Desktop, navigate to the
  Resources
  tab in
  Settings
  , and then
  under
  Network
  select
  Enable host networking
  Procedure
  Create and start the container as a detached process. The
  --rm
  option means to remove the container once it exits/stops. The
  flag means to start the container detached (in the background).
  docker run --rm -d --network host --name my_nginx nginx
  Access Nginx by browsing to
  http://localhost:80/
  Examine your network stack using the following commands:
  Examine all network interfaces and verify that a new one was not created.
  ip addr show
  Verify which process is bound to port 80, using the
  netstat
  command. You
  need to use
  sudo
  because the process is owned by the Docker daemon user
  and you otherwise won't be able to see its name or PID.
  sudo netstat -tulpn
  grep :80
  Stop the container. It will be removed automatically as it was started using the
  --rm
  option.
  docker container stop my_nginx
