Exit Codes
Common exit codes associated with docker containers are:
Exit Code 0: Absence of an attached foreground process 前台程序进程结束
Exit Code 1: Indicates failure due to application error 应用报错
Exit Code 137: Indicates failure as container received SIGKILL (Manual intervention or ‘oom-killer’ [OUT-OF-MEMORY]) 被手动干预杀死进程，或者违反系统限制被杀
Exit Code 139: Indicates failure as container received SIGSEGV
Exit Code 143: Indicates failure as container received SIGTERM
举例，
01 （Exit Codes 0）
docker run hello-world 进程结束，exit code为0
02 （Exit Codes 1）
程序自身崩溃报错，或者人工把dockerfile中的启动命令写错，都会报exit code 1
03（Exit Codes 137）
程序收到了SIGKILL (signal kill)信号,被手动干预杀死进程，或者违反系统限制被杀 都会报错 exit code 137
04 （Exit Codes 139）
程序 segmentation fault，程序试图访问不被允许访问的内存地址，可能是程序代码或者是基础镜像的错误，可能报错 exit code 139
05 （Exit Codes 143）
容器收到了 SIGTERM 指令，也就是停止的指令，例如docker stop
