docker - 为 Jenkins slave 编写 Swarm 文件

问题描述

我正在尝试创建一个撰写文件jenkins/slave以在我的单节点群中运行。
我使用的图像是jenkins/slave

docker run与图像一起使用的命令是docker run -i --rm --name agent1 --init -v agent1-workdir:/home/jenkins/agent jenkins/agent java -jar /usr/share/jenkins/agent.jar -workDir /home/jenkins/agent
，我的撰写文件如下所示：（
'local_registry:5000/jenkins_ansible_slave' 是构建的图像，我已将其推送到本地注册表）

  slave1:
    image: 'local_registry:5000/jenkins_ansible_slave'
    ports:
      - "22:22"
    init: true
    volumes:
      - "/home/user/agent:/home/jenkins/agent"
    command: "java -jar /usr/share/jenkins/agent.jar -workDir /home/jenkins/agent"
    networks:
      - net

slave1服务未启动，当我检查服务日志时出现此错误

知道这里有什么问题吗？

谢谢，

解决方案

添加

stdin_open: true # docker run -i
tty: true        # docker run -t

我认为这将解决您的问题。你的 docker-compose 配置应该是这样的。

  slave1:
    image: 'local_registry:5000/jenkins_ansible_slave'
    ports:
      - "22:22"
    init: true
    volumes:
      - "/home/user/agent:/home/jenkins/agent"
    command: "java -jar /usr/share/jenkins/agent.jar -workDir /home/jenkins/agent"
    networks:
      - net
    stdin_open: true # docker run -i
    tty: true        # docker run -t
