Two minor suggestions for the Dockerfile section #420
Description
Thank you for writing this clear, step-by-step tutorial. I just have a couple of really minor things to suggest:
This username should be the same one you created when you registered on Docker hub. If you haven't done that yet, please go ahead and create an account.
Please add to this that you also need to be signed in to your account (docker login -u <yourusername>).
This is the first time Docker Hub is mentioned but maybe it deserves a section on its own prior to this with a brief explanation as to why it's going to be used.
Head over to the URL with port 8888, where your app should be live.
Often what happens to me is that the app does not appear simply because the browser cache needs to be hard refreshed. That may save some frustration.
That's all.
