Q:

docker ps shows empty list

I built a docker image from a docker file. Build said it succeeded. But when I try to show docker containers through docker ps (also tried docker ps -a), it shows an empty list. What is weird is that I'm still able to somehow push my docker image to dockerhub by calling docker push "container name".
I wonder what's going on? I'm on Windows 7, and just installed the newest version of dockertoolbox.

A:

docker ps shows (running) containers. docker images shows images.
A successfully build docker image should appear in the list which docker images generates. But only a running container (which is an instance of an image) will appear in the list from docker ps (use docker ps -a to also see stopped containers). To start a container from your image, use docker run.

A:

For me, docker ps -a and docker images both returned an empty list even tho I had many docker containers running. I tried rebooting system with no luck. A quick sudo systemctl restart docker fixed this "bug".
