显然,CMD myexec param1 param2启动了一个外壳,它反过来启动了myexec(实际上这两个进程在容器中可见,在PID 1中有/ bin / sh -c myexec ….更好的方法是直接启动程序我的情况supervisord).

另一方面,CMD [“/usr/bin/python”,“/usr/local / bin / supervisord”,“-c”,“/root/supervisord.conf”,“–nodaemon”我现在能够通过主管启动和停止码头集装箱.

停泊处的相关部分Here’s docs：

The CMD instruction has three forms:

CMD ["executable","param1","param2"] (exec form,this is the preferred form)

CMD ["param1","param2"] (as default parameters to ENTRYPOINT)

CMD command param1 param2 (shell form)
