How can I "mount" a file into a directory in a docker container using docker-py?

I need to get a single file from my host machine into a per-existing directory in a docker container using docker-py. The directory shall not be overridden means mount is no option. Moving the directory to allow a shared volume between the host and the container is no option as well.

A single file on the host /tmp/hostfile.txt can be mounted into a container /tmp/containerfile.txt e.g. via pseudo code:

import docker

client = docker.from_env()
stdout = client.containers.run(
    image='ubuntu',
    name='ubuntu',
    volumes={
        '/tmp/container.txt': {
            'bind': '/tmp/hostfile.txt',
            'mode': 'ro',
        }
    },
    network='host',
    command='ls /tmp',
)

(The string stdout contains the file.txt.)
