Réaliser un développement sur une application graphique via docker

Bonjour

Mon but est de tenter faire des développements sur tellico.
Cependant, je souhaite garder mon système le plus stable possible.
Je tente donc de faire mon développement en utilisant un container docker.

En guise de test, j'ai créé une première image avec l'application tellico telle quelle est disponible des dépôts.

FROM     ubuntu:bionic

MAINTAINER test_tellico "test@noreply.com"

ENV DEBIAN_FRONTEND noninteractive

# Depots, mises a jour et installs

RUN (apt-get update && apt-get upgrade -y -q && apt-get dist-upgrade -y -q && apt-get -y -q autoclean && apt-get -y -q autoremove)


RUN apt-get install kubuntu-desktop -y

RUN apt-get install  tellico  -y

Pour utiliser le serveur X de la machine hôte, la création du conteneur se fait a l'aide de la commande suivante.

docker run -ti --net=host -e DISPLAY -v /tmp/.X11-unix tellico /bin/bash

Après déclaration du server X du PC hôte du conteneur:

xauth add nom_de_lhote/unix:0  MIT-MAGIC-COOKIE-1  eb1cb752gdad6a0815aa9d88502e483

Le lancement d'une application graphique (xclok) se réalise correctement.

Mais le lancement de tellico échoue :

Dans les conteneurs docker, ni systemctl, ni le service dbus ne sont installés.
C'est a partir de ce point que je ne comprends plus.
Les applications peuvent normalement se lancer en mode standalone (c'est à dire sans connecter a un bus de message)

Professionnellement, j'ai un autre PC sous Windows 10 avec l'autorisation d'utiliser WSL (Windows Subsystem Linux)
Dans une image WSL basé sur ubuntu (lancé via Mobaxtem qui gère un serveur X), l'installation et le lancement de tellico s'effectue correctement.
Dans ce cas non plus, ni systemctl , ni dbus d'installé.
Donc tellico se lance bien en mode standalone.

Je ne comprends donc pas l’erreur obtenu dans le conteneur docker.

Est-ce que quelqu'un a une idée  ?
