我正在raspberry pi zero上运行docker,我在启动时使用systemd启动了了望塔和我的容器。我的容器它只是工作,如果我用我的手运行它或在启动时由systemd运行但当我推新图像我的私人repo了望塔检测新版本..停止,删除并尝试运行新版本但此时容器退出与137立即(运行3秒后)。

这是退出容器的日志:

pi@raspberrypi:~ $ sudo docker logs 6f2a4282cdfe

这是inspect命令的结果:

Dockerfiledocker run ...命令中的某处,您需要提供CMDENTRYPOINT参数。您正在构建一个包含您的应用程序和依赖项的容器映像,但是没有定义实际的应用程序入口点,因此没有运行,这就是容器立即退出的原因。
