command is bash, attach is also connected to bash so that the container can be manipulated at will. Closing a connection is easy to think of, is to exit Bash:exit. But, however, this exit can cause a problem when the container stops because the 1th process exit (the Attach command Connection bash) will assume that the task is complete. As above, the container has been stopped (exited). Therefore, I recommend using the EXEC command to manipulate

And after exiting, it does not affect the 1 PID of Bash, so that the container can continue to run.Visible, after I quit the container bash, the container is still running. After I use EXEC to execute the PS command o
I have been engaged in docker recently, and it is also very troublesome to use exec to enter the docker container.
