1、线上边端环境Java服务部署在边端，docker老是重启

先看几个常用的docker指令

1.1 journalctl -u docker --since=2023-09-15【查看docker守护进程日志】

命令用于查看Docker服务的日志。该命令使用journalctl工具来访问系统的日志消息，特别是与Docker相关的日志，从哪一天日志看起，since后面跟着的是具体日期。

1.2 docker events --since=1694707200000【查看docker的事件日志】

docker events命令用于监听Docker守护进程产生的实时事件。从哪一天日志看起，since后面跟着的是unix时间戳。

1.3 docker exec -it xxx-zeienrio bash 【进入docker容器】

docker exec -it <container_id> bash命令用于在正在运行的Docker容器中执行一个新的进程，即表示进度docker 容器，xxx-zeienrio为对应的容器名或者容器ID。

1.4 jstack -l 6【查看Java的堆栈信息】

jstack -l pid 命令主要用于查看Java服务的堆栈信息

1.5 uptime -s【显示系统最后一次启动的时间 】

1.6 last reboot【查看系统上次重启时间 】

1.7 查看docker事件日志

2.0 docker事件错误码分析

2.0.1 错误码：exitCode=137

日志中出现的退出码：exitCode=137表示容器的退出代码为137。在Docker中，退出代码用于指示容器终止时的状态。

具体到exitCode=137，它通常表示容器被发送了一个SIGKILL信号，导致容器被强制终止。这可能是因为容器使用了过多的内存资源，或者超出了可分配给它的限制。

值得注意的是，137是由于信号9（SIGKILL）与128之和而得到的。Docker将信号9映射到容器的退出代码，并添加128作为基础值。

当你遇到exitCode=137时，你可以考虑增加容器的内存限制，或者检查容器内部是否存在内存泄漏或其他资源消耗过量的情况。此外，你还可以查看容器的日志以获取更多关于容器停止的信息。

2.0.2 错误码：exitCode=143

日志中出现的退出码：exitCode=143表示容器的退出代码为143。在Docker中，退出代码用于指示容器终止时的状态。

具体到exitCode=143，它通常表示容器被发送了一个SIGTERM信号，这是一个正常的终止信号。SIGTERM信号是Docker在尝试停止容器时发送的信号。容器收到SIGTERM信号后，有机会进行清理和优雅地关闭。

如果你看到exitCode=143，说明容器已经接收到停止信号并成功地完成了正常的终止操作。

请注意，与其他退出代码一样，143只是一个标识符，具体含义可能因上下文而异。你可以进一步查看容器的日志和事件来了解更多关于容器停止的详细信息。

2.0.3 网络连接失败

从日志可以看出，会出现网络连接失败的情况！

2.1 分析

1、docker events和journalctl -u docker.service的日志都显示了docker 重启了，并且将docker下面的服务也重新启动了。
2、从Java的堆栈信息上面看不出异常，而且从Java服务本身的服务日志，就是docker重启前后的日志也看不出任何异常，没有任何的内存溢出，数据库连接失败等信息，且Java服务本身的业务日志也是正常在打印的，故不是Java服务本身的问题。
3、从docker事件的日志中看到exitCode=137和exitCode=143是在docker重启以后出现的，所以也不是这个问题；exitCode=137和exitCode=143的问题，是因为，Java的堆内存启动参数设置的太小了，只有256M，后面调成了1G。
4、继续排查：开始的时候并没有想到项目上会断电啥的，然后经过同事提醒，去看下系统的重启时间，可以看到系统最后一次启动时间是：2023-09-15 14:57:11，再看下系统的启动时间日志，可以看到Sep 15 22:57 - 09:40 (4+10:42) 系统进行了重启【自动换算时区】，最后结论是系统重启导致的docker重启，docker重启导致的Java服务重启；
