Chalie, you offered nothing new in that response. You just repeated what you had done before: starting a container, finding it not listed in the ps, finding it listed in the ps -a as exited. As I said, you can't "connect" to a stopped container. I think you're wanting to find why it stopped, and that's where the docker logs command could help.

Can you please respond with words (not more commands and output), as to what you think of these answers I am offering? If they are "not working" for you, please do clarify.

am geting this error

docker 40ada09e9fe2 logs
docker: '40ada09e9fe2' is not a docker command.
See 'docker --help'

Did you heed that last command? It would show you that yoy were simply mistaken and just need to put the container id at the end of the command, like in showed in my earlier comment, so "docker logs 40ada09e9fe2".

am geting empty

it return nothing

Ok. But let's be clear: I've answered the question you asked. You cannot connect to a stopped container. You seemed initially not to realize it was stopped. 

And I offered the suggestion of using docker logs, in case it might show something to help understand why it had stopped. The fact that the image you're using shows nothing in its logs is an entirely different subject (having as much to do with how the image was made), which expands beyond your original question.

As such, you should consider creating a new question for that, if that's where you want to go with continued diagnosis.
