Centos docker-compose 显示退出代码 0 但它仍然没有运行

【问题描述】：

这是一个简单的 docker-compose 文件，它应该创建一个 centos 映像并使用暴露的端口 5000 和专用卷存储来运行。

version: '3'

services:
  mlos:
    image: centos
    ports:
     - 50:5000
    volumes:
     - ml_stor:/root/docker-compose-files/ml/docker-storage   

volumes:
  ml_stor:

但是当我运行docker-compose up 它显示 exit 0。

我也尝试删除暴露的端口 5000 和专用卷。但还是一样。

如果restart: always被添加到docker-compose， 运行几秒钟后它正在重新启动。

这是docker-compose --verbose up 命令的输出：

【问题讨论】：

  • exit 0 表示成功。
  • 但是，当我尝试启动并附加到这个操作系统时，它没有运行。
  • 您在 docker 日志中看到了什么？ docker logs -f &lt;container-name&gt;
  • 什么都没有。一片空白
  • 是的，谢谢@SachithMuhandiram。我很感激。当我将command: date 添加到我的 docker-compose.yml 时，它运行良好。所以后来我直接用它来调用它到一个dockerfile。

标签： docker docker-compose centos


【解决方案1】：

您需要添加一个入口点才能运行。否则docker-compose 将创建您的图像并退出。

例如，如果你有一些脚本，你可以放

CMD ["./myScript.sh"]

在 Dockerfile 的末尾。
