Enabling network manager inside docker

Question

I am preparing a test automation which require me to install network manager so that the code api(which uses python3-networkmanager) could be tested.

In the docker file, I tried installing:

apt-get install dbus \
                network-manager

start receiving error:

networkmanager.systems do not have hostname property.

I looked for solutions, but appears that will require:

This leaves me with an only option for mocking debian networkmanager that can communicate with python3-networkmanager.

Trying to figure out, how I can mock same?

The networking environment in Docker is _very_ different from "normal" Linux. If you're trying to write a tool that interacts with Network Manager, it probably needs to run in a full virtual machine with a normal network interface that expects to be configured. — David Maze, Dec 04 '19 at 11:51

I would like to contribute as I had to spend some time getting it to work.

Inside the dockerfile you have to add:

RUN apt-get update && apt-get install -y network-manager dbus

Also, I added a script to start the network manager:

#!/bin/bash

service dbus start
service NetworkManager start

Then in the Dockerfile you have to call this start script at the end:

COPY start_script.sh /etc/init/
ENTRYPOINT ["/etc/init/start_script.sh"]

Now you can build your container and run it like this:

docker run --net="host" -v /run/dbus/system_bus_socket:/run/dbus/system_bus_socket container

For me, it is enough to work with OrangePi and Docker without a privileged container.
