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的蚊子图像
来自ubuntu:latest的lcsf/mosquitto3，然后我添加了一些工具(ping，ipconfig)。我可以使用docker run和/bin/bash运行单个容器，但无法使用该图像创建Swarm服务。服务创建失败。以下是一些输出。
Dockerfile:FROM ubuntu:latestRUN apt-get -y updateRUN apt-get install -y mosquitto mosquitto-clientsEXPOSE 80 443 1883 8083 8883
Docker服务创建输出:overall progress: 0 out of 1 tasks1/1: preparing [========> ]verify: Detected task failure
该输出以循环形式显示，然后我使用ctrl + c停止它，使用0/1副本创建了服务，但未运行。
Docker服务ps mqtt(我的自定义名称)输出，有3个节点。ID NAME IMAGE NODE

就是这样，我希望有人能帮助我。在此先感谢您，对不起我的英语和堆栈溢出技能。

最佳答案
您的问题是您的dockerfile。您正在群集服务上运行bash命令。您需要运行一个不存在的命令
FROM ubuntu:latest
RUN apt-get -y update
RUN apt-get install -y mosquitto mosquitto-clients
EXPOSE 80 443 1883 8083 8883
CMD ["tail", "-f", "/dev/null"]
这是一个无限的tail命令，它将确保您的容器不会退出。在部署到群时，在镜像中运行不查找用户输入的命令。
