我在docker容器中有一个入口点脚本,看起来像下面这样：
@H_403_1@#!/bin/bash
echo starting up
function shut_down() {
echo shutting down
pid=$(ps -e | grep myapp | awk '{print $1}')
kill -SIGTERM $pid
exit
}
trap "shut_down" SIGKILL SIGTERM SIGHUP SIGINT EXIT
/opt/myapp
我不知道如何通过运行停放码头停在容器上来捕获发送的信号.当交互运行时,ctrl c将按预期触发它,但是docker stop命令只是等待10秒超时,并且退出而不用进入shut_down函数
我怎么可以捕获由巴基斯坦码头停止发送的信号进行一些清理？
看看
this,可以鼓舞人心:-)
