"container_port" is ignored in "HOST" networking mode

[dcvan24]

For containers in "HOST" mode, Docker does not allow a container port to be mapped to a host port different from the container one. So if a container needs to publish port 8080, its host port must be set to 8080 regardless what value is assigned to the container_port field. The container should be set to "BRIDGE" or "CONTAINER" mode if there are container ports to be mapped to ephemeral host ports.
