我正在监督下在Docker中构建一个tomcat容器.如果Dockerfile中的默认命令是
CMD supervisord -c /etc/supervisord.conf
当我调度docker stop命令时,容器成功退出,退出代码为0.
但是如果我有
CMD ["/run"]
在run.sh中
supervisord -c /etc/supervisord.conf
docker stop命令为我提供退出代码-1.在查看日志时,主管似乎没有收到指示退出请求的SIGTERM.

与之前的日志相反,在该日志中,它会收到sigterm并正常退出.

任何帮助表示赞赏.

最佳答案
通过run.sh运行该进程时,信号仅发送到该进程.除非你是

子进程将无法获得信号.
