我有一个 docker 入口点脚本，该脚本应该捕获发送到容器中进程的信号。主要应用程序是 tomcat - 嵌入在 docker-entrypoint.sh 中的 java 进程，该进程被传递给 dumb-init。容器中的流程映射如下所示：

root@mycontainer:/usr/local/tomcat/webapps/datarouter-example# ps -ef
    UID        PID  PPID  C STIME TTY          TIME CMD
    root         1     0  0 05:21 ?        00:00:00 dumb-init -- /docker-entrypoint.sh
    root         6     1  0 05:21 ?        00:00:00 bash /docker-entrypoint.sh
    root        14     6  1 05:21 ?        00:08:57 /jdk-13.0.1/bin/java -Djava.util.logging.config.file=....
