我无法使用基于 ubuntu 的映像部署 Docker Swarm 服务
I can't deploy a Docker Swarm service using ubuntu based image
我是 Docker/Docker Swarm 的新手，我想在 Swarm 上创建自定义 mosquitto 服务。我创建了一个自定义蚊子图像
lcsf/mosquitto3 来自 ubuntu:latest，然后我添加了一些工具（ping、ipconfig）。我可以 运行 使用 docker run 和 /bin/bash 的单个容器，但我无法使用该映像创建 Swarm 服务。服务未成功创建。下面有一些输出。
Docker文件:
FROM ubuntu:latest
RUN apt-get -y update
RUN apt-get install -y mosquitto mosquitto-clients
EXPOSE 80 443 1883 8083 8883
Docker 服务创建输出：
overall progress: 0 out of 1 tasks
1/1: preparing [========> ]
verify: Detected task failure
这个输出显示在一个循环中，然后我使用 ctrl+c 停止它，服务已创建，但没有 运行，有 0/1 个副本。
Docker service ps mqtt (my custom name) 输出，有3个节点。

您的问题是您的 dockerfile。您正在 运行ning bash 集群服务命令。您需要运行一个不存在的命令
