Great article!

I got struggled a bit then I went to double check and found a typo error on your Dockerfile

COPY — from=node /app/dist/ng-docker-example /usr/share/ngnix/html

should be

COPY --from=node /app/dist /usr/share/nginx/html

Besides that, to run also I needed to change a port from 5801 to 80

docker run -d -p 5801:80 ng-docker-example:latest

but at the same time I was working with my angular project, not yours so I am not sure if there is any difference between it.

Thanks again, it was very nice to make my app working on Docker and thanks to your article it started to work!
