Besides the comments on your question that already pointed out a few things about Docker best practices you could anyway start a backgroundprocess from within your start.shscript and keep that start.shscript itself in foregroundusing the nohupcommand and the ampersand (&). I did not try it with mongodbut something like the following in your start.shscript could work:
除了对您的问题的评论已经指出了有关 Docker 最佳实践的一些事情之外，您无论如何都可以从脚本中启动后台进程，start.sh并使用命令和与符号 ( )将该start.sh脚本本身保持在前台。我没有尝试过，但您脚本中的以下内容可以工作：nohup&mongodstart.sh
#!/bin/sh
...
nohup sh -c mongod --dbpath /test &
...
