I finish a work about "docker" and it give me the url, but i can't open it. What should I do to see the website?

enter image description here

enter image description here As you can see, it finished and show "Running on http://0.0.0.0:5000/". But when I copy this url to my firefox, it shows failed. Is I used url in a wrong way or something else I did wrong？ So, what could I do to see the website? Any words from anyone could help. Thanks a lot.
