Docker run normally but docker ps show nothing

Question

docker run not working on my machine (Ubuntu 16.04).

Answer 1

It's likely docker run did work, but since you did not specify any command to run, the container stopped working just after starting. With docker ps -a you should see some exited ubuntu containers.

If you run the container as daemon (-d) and tell it to wait for interactive input (-it) it should stay running. Hence docker run -d -it ubuntu should do what you want.

Answer 2

I did not understand the question correctly. What you want to do is bash connection maybe parameter to execute is incorrect

sudo docker run -t -i /bin/bash ubuntu

Go for it
