Je suis un débutant dans Docker/Docker Swarm et je veux créer un service mosquitto personnalisé sur Swarm. J'ai créé une image personnalisée de mosquitto lcsf/mosquitto3
d'ubuntu:latest, puis j'ai ajouté quelques outils (ping, ipconfig). Je peux faire fonctionner un seul conteneur avec docker run
y /bin/bash
mais je n'arrive pas à créer un service Swarm avec cette image. Le service n'est pas créé avec succès. Il y a quelques résultats ci-dessous.
Dockerfile :
FROM ubuntu:latest RUN apt-get -y update RUN apt-get install -y mosquitto mosquitto-clients EXPOSE 80 443 1883 8083 8883
Docker service create output :
overall progress: 0 out of 1 tasks 1/1: preparing [========> ] verify: Detected task failure
Cette sortie est affichée en boucle, puis je l'arrête en utilisant ctrl+c, le service est créé, mais ne s'exécute pas, avec 0/1 répliques.
Docker service ps mqtt (mon nom personnalisé) output, il y a 3 noeuds.

Voilà, j'espère que quelqu'un pourra m'aider. Merci d'avance et désolé pour mon anglais et mes compétences en Stack Overflow.
