Swarm 为 Jenkins 代理撰写文件

Question

我正在尝试为

jenkins/slave

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

用于图像的

docker

run

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' 是构建的映像，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收到此错误

知道这里出了什么问题吗？

添加

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

我认为这会解决您的问题。 您的 docker-compose 配置应该如下所示。

  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
