Hello to everybody

I have the follow problem, I installed on my raspberry pi docker.

docker --version

Docker version 19.03.12, build 48a6621

pi@raspberrypi:~ $ docker version

I test that all it works fine with hello word image.
I run it and that’s the result:

pi@raspberrypi:~ $ docker run hello-world
Unable to find image ‘hello-world:latest’ locally
latest: Pulling from library/hello-world
4ee5c797bcd7: Pull complete

Status: Downloaded newer image for hello-world:latest

The same situation with tobi312/rpi-nginx, it’s downloaded but not in run, I can see stopped with

docker ps -a

Does somebody have any idea?

Thanks a lot

Best Regards

Alessandro
